Arduino Tutorial: Control LED Brightness with PWM for Breathing Effect
In the previous Arduino tutorial, we learned how to control the on/off state of an LED. In this tutorial, we will learn how to control the brightness of an LED using Pulse Width Modulation (PWM) with Arduino. https://www.ninniku.tw/getting-started-with-arduino-lighting-up-an-led/ The LED brightness is controlled by adjusting the duty cycle of the PWM signal. The duty cycle is the ratio of the time the signal is on to the total time of one cycle. The larger the duty cycle, the brighter the LED, and vice versa. Step 1: Connect the Circuit We will keep Pin 8 as a digital control circuit, and connect it to the red LED on the circuit. Another…
