“You may have seen many light-sensitive switch circuits based on an LDR sensor. Usually, the sensitivity of the LDR based light sensor is poor. We wanted a very sensitive light switch hence we decided to make a circuit based on …
“I designed the circuit board for the NE555 timer and it works! Try it too! Hello! My name is Vladimir, I am a programmer and electronics developer. Analog circuitry has always been my weak point, and therefore the idea came …
“FM transmitters/receivers are among the top favorite circuits of any electronic enthusiast. In this article/video, I have introduced a complete digital FM receiver design that has equipped with an LCD screen and three push-buttons. It can search for …
“Monitoring the voltage level of a 12V Lead Acid Battery (SLA) is easy and simple with this project. The board is made using an ATMEGA328 micro-controller and 12 x 5mm LEDs. The ATMEGA328 microcontroller senses the analog voltage on A3 …
“Hi and happy holidays to you all! If you take look at my profile, it’s clear that I’m somewhat of an LED addict. This addiction more or less began a few years ago when tinkering with commonly available …
“This is an isolated analog input module that is useful for interfacing Analog signals of various types originated from analog sensors and field devices. The module is very useful for in-process controls, factory automation, industrial applications, etc. Interfacing an analog …
“Previously I had introduced simple raspberry pi (Hereinafter as RPI) operational status indicator circuit. This time, Ill explain some more useful indicator circuit for RPI running as headless (without monitor) manner. The circuit above shows CPU temperature into 4 different …
“This is a 8x8 WS2812b NeoPixel LED matrix that is completely flat surface and has the same 1.6mm height as a normal PCB. I always had this idea of what would have happened if we can put the components …
“Several years ago I built a CNC router with the express purpose of creating my own guitar. Unfortunately however, I never got around to it. Two years back I was getting into 3D printing in a big way and started …
“I wanted an efficient way of stepping down higher voltages from LiPo packs (and other sources) to 5V for electronics projects. In the past I have used generic buck modules from eBay, but the questionable quality control and no name …
