Looking for a simple circuit to control the light intensity of Light Emitting Diodes (LEDs) or similar lighting sources? Here is an Arduino based circuit with three independent pulse width modulated ...

Recently, we published an entry-level Arduino project with a single seven-segment LED display. Although it’s an amazing DIY project, we noted that most of the readers are looking for more advanced ...

Potentiometer: One end to 5V, the other to GND Middle pin to Arduino A1. LEDs: Red LED: Arduino pin 10 with a 220Ω resistor. Yellow LED: Arduino pin 9 with a 220Ω resistor. Green LED: Arduino pin 8 ...
