At the center of every Arduino UNO you’ll find Microchip’s ATmega328p microcontroller.
It’s the brains of the operation, without it, your Arduino wouldn’t be able to do any of the amazing things it’s famous for.
This Arduino Uno shield will give you the oportunity to burn the ATMEGA328P bootloader.
After that, you can use an FT232RL USB/TTL converter to push codes inside the chip.

Le but de ce projet est de contôler la température d'un balon d'eau chaude sanitaire (ECS) grâce à 2 capteurs (un en haut et l'autre en bas du ballon) pour commander une chaudière via un contact sec (normalement ouvert ou normalement fermé).
La commande de la chaudière se déclenche dès que la température de la sonde haute descend en dessous du seuil fixé et s'arrête dès que la...
This is my final design for a NIXIE clock. I have made several and this is the best one. My gift to the universe is this in the public domain. Feel Free to make one and tell me about if you like.
the arduino code is attached, I suggest you use it as a starting point for your own code. From it you can see what pin is connected to what and how I implemented the multiplexing, you may have a more ele...
(still work in progress, not fully tested)
A smart MIDI box based on a STM32 "blue pill" microcontroller (STM32F103C8T6).
Software is hosted on Github: https://github.com/retro16/MidiBox
Uses a HD44780 16x2 LCD screen with the usual I2C converter.
The interface is made of 4 push buttons arranged in a directional pad (up, down, left, right).
A SD card can be attached for more features.
This my first take on an Arduino Nano PLC(ish) device.
It uses standard discrete components and thus is rather cheap to build.
But discrete components do take up a bit more space.
The inputs can accept up to 24v and are connected to the analoge pins, using optocouplers the inputs are electrically isolated
from the Arduino.
The outputs uses relays, the outputs from the relay uses an external sourc...
PCB muon detector
Schematics designed by Robert Hart:
Thanks to Robert Hart for his fantastic ideas, please check his site for further experiments:
This project uses 3 Geiger tubes to create a muon detector, it also uses a step up boost DC-DC to convert from 5V to 400V for Geiger tubes.
This main PCB has...
