Arduino – Turn LED ON and OFF With ButtonIn this Arduino tutorial I will show you how to turn an LED on and off with a push button. In fact, we’ll do 2 slightly different applications.First, we will power on the LED when the button is pressed, and power off the LED when the ...
LedUtil Library for Arduino This library allows you to control a LED. For each instantiated object it is possible to control only one key. The "liga" method using to turn on a LED. The "desliga" method using to turn off a LED. The "pisca" method apply blink effect on LED. For more...

If this new to you, I recommend getting familiarized with the tools at this point and doing something simple such as writing and downloading a code to make the on-board LED on the Wemos D1 Mini blink. The code uses various libraries such as fauxmoESP and ArduinoOTA. General instructions...
We will use the SPI communication, so we need to connect the suitable SPI pins on the Arduino board and our controller board. Now, using the Arduino IDE, we need to open the ArduinoISP example sketch and upload it to the Arduino Nano board. With this code the Arduino Nano is now capab...
Open the Arduino IDE serial monitor. Point your remote control at the IR LED receiver (3 pin) and press the Volume Down button. You will see numbers being displayed on the Serial Monitor. Record the short number generated when you pressed your remote button. In my case, the volume down ...
上传程式码之后,按下Ameba的Reset按钮,就可以看到LED灯泡随着时间渐暗与渐亮。 Afterwards, upload the sample code and press the reset button. Then you can see the LED fades and lights alternately. Code Reference You can find detailed information of this example in the documentation of Arduino: ...
