Fading an LED ON/OFF – Arduino Basics

Last Updated on December 5, 2024 by Swagatam 2 Comments

simplefade pin9 schem

In this post I have explained a basic Arduino function where I have explained the process of fading an LED ON/OFF through some basic code implementations. Creating a Fading Effect We see how to use an analogwrite() function in order to implement a fading ON/OFF of an LED. The function incorporates PWM pulses across a […]

IC 555 Automatic Emergency Light Circuit

Last Updated on January 2, 2024 by Swagatam 68 Comments

simplestautomaticemergencylightcircuitusingIC555

The discussed 2 simple IC 555 based emergency lamp system employs just a single IC 555 and yet is able to switch more than 20 LEDs directly, it will illuminate the LEDs only during the absence of mains power and ambient light. 1) Using IC 555 as a Comparator The proposed circuit is not only […]
