SINGLE CHANNEL RELAY MODULE
ZAFAR May 15,2025
This is a compact single-channel relay module PCB designed to control AC appliances using microcontrollers like Arduino or ESP32. I created it to offer a safer, cleaner, and more reliable alternative to bulky relay modules. It features a flyback diode, LED indicator, and screw terminals for easy use. The PCB ensures safe switching with optional optocoupler isolation. It's ideal for home automation and DIY IoT projects. I tested it by switching a light bulb using an ESP32, and it worked flawlessl...

Building an E-Paper Analog Clock with ESP32 - Full Tutorial
Pavleski May 15,2025
 In several of my previous projects you could see various unusual clocks , including several in the retro Analog style. This time I will present you another clock from this group, but now on a E-paper Display. Specifically, in this project I used the CrowPanel ESP32 4.2” E-paper Display module with built-in ESP32S3 MCU. I have this display from a previous project of mine and I can tell you that it is very practical in the sense that there is no need to connect components and solder, an...

Quarter-Round WS2812 Display
McEvoy May 14,2025
I wanted to make a clock that changed from green to red over the course of an hour to reinforce time passing. I wanted to avoid watching "just one more episode" or neglecting chores until bedtime.The quarter-round design makes the units modular, so I could put one in the corner of a window, two that form a rainbow, and four that make a circular clock.I assembled my clock using some laser-cut pieces, but the same parts could be made with hand tools. I also soldered wires to the back, but the Dupo...

ATmega328PB NANOx(PB) New and Improved Arduino NANO
Grigoriadis May 06,2025
I like the ATmega328 and I use it almost everywhere (except some special cases where I need more Power, then the ESP32 comes to help), it has enough Flash, Ram and Power for the Majority of my Designs. What I always missed was one more of every Interface (UART, SPI, I2C) as well as a couple of more GPIOs in the same TQFP32 Package. Few Years ago the Successor of the venerable 328P, the 328PB hit the Market, but I couldn't find any NANO Version of it (for Bread-boarding) on the Asian Market, so I...

H bridge Brushed Motor Driver with N channel mosfets and High-Side driver
Ertan Apr 19,2025
This is a H-Bridge motor driver. It uses IR2104 mosfet drivers, one 7812 to power mosfet drivers and 4 mosfets to control the motor. 4 mosfets can control the motor direction and brake. IR2104 controls one high side and one low side mosfet. When one High side and one Low side mosfet starts to conduct motor starts to turn and when other 2 mosfets conduct motor starts to turn the opposite way. When two low side mosfets are conducting motor can brake safely. This logic is easly implemented on the b...
