Controlling an LED with a pushbutton is one of the best starting points when learning Arduino. In this tutorial, you’ll learn how to wire a simple circuit and write basic code that lets you turn an LED on and off…
In this tutorial, we’ll build a simple but powerful Arduino LED Dimmer using a potentiometer and PWM (Pulse Width Modulation). You’ll get to understand how PWM works, and how you can control the brightness of an LED based on the…
Digital signals are binary — they can only be either 0 or 1. Analog signals, however, have a continuous range of values and are not limited to just two states. Both types of signals are found in electronic systems, but…
