Click to seeMy Potentiometer Demo Step 10: RGB Lamp *In this step, we are going to make a Multicolor RGB Lamp. *Let's use 3 potentiometers to change the value of Red, Green, and Blue and a Multicolor LED. Connect the circuit diagram as shown ...
First, we will power on the LED when the button is pressed, and power off the LED when the button is not pressed. And then we’ll modify the program to toggle the LED’s state only when we release the button. For more info on each component, also check out thisArduino LED tutorial...
Example 例子 Sets the output to the LED proportional to the potentiometer. the value read from 1. int ledPin = 9; . 2. } 3. 4. void loop() 5. { 6. . 7. } 复制代码 代表事件的开始与事件的循环。 假如控制过程比较复杂, 一般就要设置多个子事件, 把复杂的过程进 行分解,每一个子事件...
