This post show how to make a Simple Arduino LED Dimmer Circuit using PWM, as PWM changes voltage by changing square wave duty cycle; also it changes duty cycle to make LED more or less bright. Therefore, more power means more brightness. Arduino Code: Circuit Working: Parts List: Components Quantity Resistor 220Ω 1/4 watt 1 […]
