Electronic Projects
Electronic projects including microcontroller and Arduino projects with circuit diagrams (schematics), electronics parts lists, source files, videos and all the information that you will need to build the projects.
Open-source electronics projects for beginners to advanced levels.
Raspberry PI Serial Port and Breakout Board Project
A simple single-sided board that connects a RS-232 serial port to the Raspberry PI and breaks out some of the PI's pins for experimentation.
Build an LED Open Sign
Build an open sign for a shop or store using LEDs and an ATtiny2313 AVR microcontroller.
Build a Tiny USB LED Torch
Build this tiny USB LED torch and power it from a USB power pack or any USB host port.
Open Source PLC
The OSPLC SMALL BRICK is an open-source PLC (programmable logic controller) that can be programmed using open source C language programming tools.
This project includes photos of the PLC and circuit diagrams of the PLC boards.
Build a CPLD Board with a Xilinx CPLD
Build this single-sided Xilinx CPLD board at home and experiment with CPLDs and hardware description language (HDL).
Arduino LCD Voltmeter with 4 Channels
Analog channels A2 to A5 on an Arduino Uno are used to measure four different voltages. The measured voltages are displayed on a 16 character by 2 line LCD.
