How To Connect A Hammer Drill Directly Without A Button

How to connect a button to Arduino How to connect a button to Arduino. Connection types, diagrams, practice

3 Incorrect button connection

To connect a normally open clock button to the Arduino, you can do the simplest way: connect one free conductor of the button to power or ground, the other to the digital pin of the Arduino. But generally speaking, this is wrong. The fact is that at moments when the button is not closed, electromagnetic interference will appear on the digital output of Arduino, and because of this, false positives are possible.

Wrong button connection to Arduino

To avoid pickup, the digital pin is usually connected through a large enough resistor (10 kΩ), either to ground or to power. In the first case, it is called pull-up resistor circuit, in the second pull-down resistor circuit. Let’s take a look at each of them.

Instructions for connecting a button to Arduino

  • Arduino UNO or other compatible board;
  • Clock button;
  • 10 kΩ resistor (here is an excellent set of resistors with basic ratings from 10 Ω to 10 MΩ);
  • Breadboard;
  • Connecting wires (I recommend this set);
  • Personal computer with Arduino IDE development environment.

How to connect a button to Arduino

Seems like it could be easier than connecting a button? Nevertheless, there are pitfalls here. Let’s figure it out.

Replacing a button in an electric drill

Quite often, the electric drill stops working due to the breakdown of its button (it does not turn on, the number of revolutions is not regulated), we disassemble the drill, we try to do something, and when we understand that the button turns out to be many wires from it, and which one was unknown where?
You buy a new button, and how do you connect it? To do this, you need a diagram of its connection:

Button connection where the capacitor has three terminals

Reverse button connection

In order for the engine to start working in the opposite direction, you need to swap the connection of the wires to the brushes (in the button with a reverse, this is done using the switch lever).

I want to draw your attention when buying a button, it must correspond not only to the size, but also to the power of your drill. Let’s calculate: we have a 650W drill, P = UI, I = 650/220 = 2.95A, it turns out we need a button on U =

220V, I = not less than 2.95A, then the BUE-3 button is suitable for us

We connect the Printer to the Laptop via Wi-Fi

Let’s figure out how to connect a Printer to a Laptop via WiFi without a Router. We have previously covered a similar topic of connecting an MFP printer to a laptop via a router, but now we will figure out more locally how to install a WiFi printer to a laptop without a router. Consider possible problems, why a laptop may not see your printer when connected via Wi-Fi and similar errors. First, let’s look at various options for connecting a wireless printer to a laptop without using a router.

WiFi hotspot connection

First, let’s consider the option of how you can connect a wireless WiFi Printer without a router using the direct network connection setting (peer-to-peer wireless network). For this setup, you will need to complete the following points (I recommend the first two only as a last resort if your laptop does not see the printer’s wireless network, for advanced users):

  1. First, we reset the settings to factory settings (see user manual);
  2. After that, we perform the basic configuration, according to your user manual;
  3. Make sure the wireless network is working (the color WiFi indicator on the panel should be blinking / on);
  4. Next, from the PC, we search for the wireless Wi-Fi network of our printer, as a rule, this is the name of its model, for example HP;
  5. We establish a connection, a laptop to a printer (as a rule, a password is not required);
  6. Install software for (Driver, see CD-ROM from the printer).

After completing all the steps, your model will automatically appear in the list of available devices, and you can print. There are disadvantages of connecting through an access point, and they are obvious:

  • The connection is not secure;
  • Lack of multi-connection networks from a laptop;
  • Manual connection every time.

How to turn on the smartphone if it is off, the power button does not work

The current situation, of course, is not encouraging, but there is still hope. However, success is not guaranteed, since it will depend on the brand and model of a particular device.

First of all (and this option no.) we try to connect the smartphone to a standard charger. This is in case it does not turn on due to battery discharge. Some models may automatically turn on at this stage (although, unfortunately, the probability of such a quick solution to the problem is extremely low). We connect to the charger and hold down the volume control button for a while, suddenly the boot menu appears on the smartphone screen.

Option number 2. If the battery is not completely discharged (at least 5%, or better, more, the charge indicator is displayed even if the smartphone is turned off), disconnect the device from the mains charger and connect it to a computer or laptop via a USB cable. Our Motorola Moto G then turned on instantly without any buttons.

If yours has not turned on, then there is still option number 3. To be fair, let’s call it a chance. Since it can work only if, before turning off the smartphone, you activated the USB debugging mode on it, and now you can try to turn on the device through the command line of the computer. In general, if the conditions are met, then install ADB on the computer and open a window with a command line. After that, we connect the smartphone via USB, write in the command line adb reboot and press Enter.

Broken or not working power button how to turn on the smartphone

For example, the power button of a smartphone does not work. Crashed, broke, etc. And now the question arises, how to turn on the smartphone without this very button?

Old and new, expensive and cheap, on Android or iOS, fashionable and not so all smartphones and tablets can break.

Not in the sense of failing and freezing, namely, failing, as a rule, as a result of sudden mechanical and other adverse effects. Sometimes to smithereens, but more often with less tragic consequences, one of which is just a mechanical failure, due to which the power button does not work.

It’s a shame, annoying. It turns out that the device did not seem to have suffered much, but the sense from it suddenly became much less.

In fact, if you were lucky, say, to drop your smartphone (or tablet) so delicately that it was the power button that got most of all, then further this adventure, as practice shows, can develop for you along two plot lines: the smartphone remained on, but you cannot unlock it, or it has turned off completely, and now it is not clear how to turn it on, since the power button does not work.

Actually, the conditions of the tasks are formulated. Now you can try to solve them. So:

how to turn on the smartphone if the screen is locked and the power button does not work

As they say, already lucky, so lucky. If the power button stops working, but the smartphone does not turn off, then everything is somewhat simpler. But you still have to be quick and turn off the screen of the device so as not to waste the battery charge in vain (just in case).

Owners of Samsung Galaxy and iPhones shouldn’t be very nervous at all, because even with a smashed power button, they can then unlock their smartphones with the Home button. In addition, many modern models, including those for which the Home button is not provided by the design, can be woken up by tapping twice on the screen (of course, if this option is active).

Another thing is when there is no Home, and the screen does not want to turn on (or cannot). Then you need to either connect your smartphone to the charger, or ask someone to call it. Also. If the power button does not work, you can press the physical camera key, if there is one, thus launch the corresponding application, and then simply exit this program to the main menu. It is not very convenient, but then you can download a suitable program to quickly unlock the screen, which will significantly simplify the problem for a while. The main thing is not to forget about the battery level in all this fuss.

For example, the application Power button to Volume Button Allows you to emergency transfer the function of the power button to the sound control button; from Gravity screen the smartphone turns off automatically if you put it on a flat surface or in your pocket, and turns on if you take it in your hand; Shake Screen On Off The screen can be turned on / off by simply shaking the smartphone lightly if the power button is not working. This should be enough for the time until you get to the nearest service center.

Drill button connection diagram we fix the tool ourselves!

Checking the electric motor: causes of breakdowns and repairs

There are several reasons for drill armature or stator breakage. First of all, this is the illiterate operation of the device. For example, many users simply overload the tool, carrying out work without interruption. This results in the drill motor having no time to rest. The second reason lies in poor wire harness, which are often found in cheap models. That is why breakdowns of cheap tools are much more common. In this case, repairs must be carried out using a specialized tool. And it will be better if you entrust this work to professional specialists.

However, if it was decided to carry out the repair on its own, you will certainly have a question how to do everything right? As you already understood, an electric drill suffers from breakdowns of the armature and stator, and this can be checked by several signs, for example, when the tool suddenly sparks during operation. If there are no clear signs, you can use an ohmmeter.

The stator is changed like this:

  1. First, carefully disassemble the device case;
  2. We remove the wires and all internal parts;
  3. After finding out the reasons for the breakdown, we change the spare part to a new one, close the case again.

How to fix the problem?

Unfortunately, a tester will not be enough for you to check the performance of the tool, which is due to the fact that most of the buttons of the device are equipped with a smooth speed control, and therefore a conventional tester may give you incorrect data. In this case, you will need a special wiring diagram for the drill button. Often in tools, one wire is connected to a terminal, and therefore pressing the button at the same time will ring the terminals. In the event that the light comes on, everything is fine with the button, but if you notice a malfunction, it’s time to replace the button.

When replacing, keep in mind that the circuit can be either simple or with a reverse. Due to this, all work on replacing the button must be carried out exclusively according to the scheme, without adding anything from yourself. So, the part must be suitable in size and correspond to the power of the tool. At the same time, calculating the power is quite a simple task. We use the formula P = UI (taking into account that the power of the drill is 650 W), I = 2.94 A (650/220), which means that the button should be at 2.95 A.
