A pull-up resistor sets the initial state of the push-button as HIGH while a pull-down resistor will set the current state as LOW. Here’s the circuit diagram for the connection: From the circuit above, you can connect a push-button to the Arduino board by connecting: One leg of the...
On the Arduino Uno board used for this example, pin 13 has an LED connected to it — therefore you should see a tiny orange LED on your Arduino switch on. Click the upload button in the IDE and wait for it to say ‘Done uploading’ before doing anything else....
I’ll be using theSRD-05VDC-SL-C 5V relayin this tutorial because it’s very popular among Arduino and DIY electronics hobbyists. Let’s start with seeing how the 5V relay works, then I’ll show you how to set it up on the Arduino and give you some code to get it working. BONUS...
You can also set a custom button inside the Serial Bluetooth application. For example, a HIGH and LOW values button can be created. This way, you don’t have to manually type the values. Instead, you just have to press the shortcut button, and it will execute the instruction you set. ...
ok so i am new to arduino. i am trying to have one button turn on the led witch is in pin 13 and another button to turn it off but im having problems. when i press the button it turns on when i let off the button it goes off. here is my code so far.c
2. When a button is pressed, the column pin is pulled LOW since the current from the HIGH column flows to the LOW row pin: 3. The Arduino now knows which column the button is in, so now it just needs to find the row the button is in. It does this by switching each one of the...

In this tutorial I will show you how I build an Arduino RC Airplane. Also, I will show you how to control it using a custom build Arduino RC transmitter...
To do this, go to the “Power & Battery” tab in the left hand pane. Click the Calibration button at the bottom right. Enter the measured voltage in the popup box, then click Calibrate and it will ask to apply a new voltage scale. That’s it. ...
In this tutorial I will show you how I built an Arduino based hexapod. As the name suggests, the hexapod has 6 legs but in addition to that, it also has...
