Then install our Arduino code to get some LEDs blinking immediately. Our library is Adafruit_GFX © Adafruit Industries https://learn.adafruit.com/i31fl3731-16x9-charliplexed-pwm-led-driver Page 5 of 41compatible so you can draw lines, circles, text, and small bitmaps if you want more ...
Code to Note pinMode(2, OUTPUT)- 在使用Arduino的一个引脚之前,你需要告诉Arduino Uno R3它是INPUT还是OUTPUT。 我们使用一个名为pinMode()的内置“函数”来执行此操作。 digitalWrite(2, HIGH)- 当您使用引脚作为OUTPUT时,您可以将其命令为HIGH(输出5 V)或LOW(输出0 V)。

This code results in a LED (connected to pin 13) blinking on and off repeatedly, with each state (on and off) lasting for one second. More Arduino Tutorials
pinMode(2, OUTPUT) − Before you can use one of Arduinos pins, you need to tell Arduino Uno R3 whether it is an INPUT or OUTPUT. We use a built-in function called pinMode() to do this.digitalWrite(2, HIGH) − When you are using a pin as an OUTPUT, you can command it to...
Finally, connect two LEDs at the digital pin 7 and 8 and upload the code on your Arduino board and open the Serial monitor. You will see a counter is running once in 500ms with task name as shown below. Also, observe the LEDs, they are blinking at different time...
