[Arduino Super Introduction #24] Mini Project: Automatic Lighting | Let's Automatically Turn on an LED When It Gets Dark

In the previous chapter, we used a light sensor to read the ambient brightness as a value from 0 to 1023.This time, we will ...

[Arduino Super Introduction #13] Lighting an External LED | Let's Build Our First Circuit on a Breadboard

Last time, we learned about the anode and cathode of an LED, how to distinguish their orientation, and the role of a resistor in limiting current.This time, we will combine an Arduino, a breadboard, ...
