“Don’t buy a universal remote, make one. It’s cheaper, funner, universal-er, kind of, and you get to learn the ESP8266, kind of. If you have a hungry toddler like I do, you might also be missing some of …

“I really like the popular set-up of 2 servos arduino insects on youtube. When I looked at it, I always remember what BEAM robotic guys did long before that set-up became favorite. These people who are analog robot fanatics did …

“This is a simple Infrared LED and Photodiode tester using Arduino-compatible microcontroller. Purpose: I received a new batch of IR LEDs and IR photodiodes. I need to test them before signing them off. I have limited tools at home. So …

“A line follower robot is the one which follows a dark line drawn on a light colored (white) background.The working is explained with three sections, one is the input section where the lines are detected, the second one is …

“LUX Meter project has been design to measure the illumination. Illumination is luminous flux falling on surface area of photo diode. This illumination converted to corresponding voltage using Op-Amp circuit.”

Today we will build a circuit that detects the interruption of an infrared beam allowing an alarm to be created. The LM358 IC has two comparators. Pin 3 which is the non-inverted end of the voltage comparator is connected to …

Today we will build a circuit that uses an LED in a curious way - to detect brightness. We all know that LEDs have a certain color but some of these LEDs can also detect light. Obviously they do not have …
