“This project provides an economical and precise solution for DC current sensing and display on an OLED display. This board uses the ACS715T-20A hall effect-based linear current sensor chip, 0.96 Inch I2C OLED Display and Atmega328 microcontroller chip …
“This synth is a pulse width modulated oscillator, routed through a light-controlled resonant low pass filter. The “growling” oscillator tonality is supplied via a PWM and an awesome high-resonance low pass filter. The oscillator is controlled via 2 Light dependent …
“This is a 3-channel, PWM based current-adjustable LED driver designed for RGB LED control. The circuit has been designed to control high current RGB LEDs or RGB LEDs strip. Colors of the three RGB LEDs can be set using 3 …
“Recently Great Scott built his DIY version of a tachometer which I thought was very cool. But using an ATmega for this job, I found a bit overpowered. So I tried to force all tasks (measurement, calculation, I²C protocol and …
“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 …
