10x10 RGB Led Matrix

“I’ve build a 10x10 RGB Led Matrix Simulator on circuits.io because I’ve allready build a 10x10 RGB Matrix in real life. This one is for testing code and not damaging anything on the real one. So basically …

2.5A Bipolar Stepper Motor Driver using A3979

“The tiny board designed using A3979 IC from ALLEGRO which is complete micro stepping driver with built in translator. The translator is the key to the easy implementation of the A3979. It allows the simple input of one pulse on …

3D Printed Arduino OLED Watt Meter

“Have you ever wanted to know how many watts or how much current an item uses or even its operating voltage? This simple and easy project can provide you with that crucial information while keeping costs under $7. I primarily …

4 Channel Large Current Relay Board

“4-Channel Relay Board is a simple and convenient way to interface 4 relays for switching application in your project. The project has large Relay which can switch current up to 20Amps.”

555 Useless Machine

“Almost every project that I made in my life use arduino or just atmegas, but on last electronic lesson in my school I found small integrated circuit called 555. I have heard about it before but I was thinking that …

7 Segment Up/Down Counter

“The method I use to make PC Boards, is called the “Heat Transfer” method, using Press-n-Peel transfer paper. After applying the Press-n-Peel to a blank PC Board, I use a standard A4 laminator to transfer the toner from the Press-n-Peel …

A Bidirectional Visitor Counter using AVR ATmega16

“This counter system built using AVR ATmega16 can be used to count objects passing in a converyer belt or peoples entering of leaving a room. It is bidirectional, that means if a person enter the room, it will increment the …

A fast µC to FPGA bus

“For reasons which will become clear later, I ‘d like to exchange data quickly between an STM32 µC and an FPGA. SPI is a serial bus, which can be pushed to several dozen Mbit/sec - but what if we want …

A Little Joule Theif Flashlight Charger for Smartphones

“This idea appeared to me by coincidence and I thought I’ve ever done no more Instructable and that’s why I have this idea Documented have fun and reverse engineering or reading :)”

Arduino Solar Tracker (Single or Dual Axis)

“If you ‘ve installed solar panels on a camper van to provide you with electricity on your camping trip or at home to supplement your electricity usage or take your home completely off grid then you probably know that the …
