In this post we are going to construct LED strip controller circuit using Arduino, which can turn ON/OFF and decrease/increase brightness of LEDs using ordinary IR (Infrared) remote. What is LED Strip Light? (For noobs) If you are not familiar with LED strip lights, let’s understand what it is. LED strips (sometimes called as ribbon … Read moreControlling LED Strip Light ON/OFF and Brightness with any Remote Control
The post explains a simple foot activated staircase light circuit comprising of a chain of LEDs which activate sequentially in response to each climbed step. The idea was requested by Mr. Dwayne. Circuit Objectives and Requirements I’m hoping you can help me. I am hoping to make a LED light up staircase. Using LED light … Read moreMake this Foot Activated Staircase Light Circuit
The post explains how to make a chasing “WELCOME” display circuit sign board, which illuminates each alphabet sequentially until all the 7 alphabets are lit and then the whole display shuts off, the cycle continues permanently as long as the circuit is powered. Overview I have already discussed a similar concept explaining a bar graph … Read more“WELCOME” Chasing LED Display Circuit
In this post we learn how to make a sunrise/sunset simulator circuit using LEDs and just a couple of BJTs. The idea was requested by Mr. Jerry Circuit Objectives and Requirements Apparently natural daylight is best for humans in regulating our circadian rhythm. I would like to build an LED lighting circuit to control ceiling … Read moreSunrise Sunset Simulator LED Circuit
