USBasp - USB ISP/TPI programmer for Atmel AVR microcontrollers based on the design by Thomas Fischl.
Programmable Signal Generator
This project describes a simple digital signal generator capable of generating a square wave from 1kHz to 68MHz with an accuracy of 1.1%. You enter the frequency on a numeric keypad, and the frequency is displayed on an I2C 128x32 OLED display.
Used components: ATtiny85, OpAmp INA331/LTC6904, OLED display (connector JP1/JP3).
Programmer for Atmega328p and ATTiny24/25/44/45/84/85
Uses Arduino Nano as ISP
Has a built in Blink test LED
ATTiny24/44/84: port 1
Atmega328p, ATTiny35/45/85: port 3
ATtiny controlled and LiPo battery powered MP3-Player using the DFPlayerMini-module featuring:
- Micro-SD-card slot,
- battery charging and protection circuit,
- battery level detection,
- OLED display,
- on/off switch,
- volume control,
- 3 push buttons to control the player.
You can directly connect a 3.7V LiPo battery and a 3W/4Ohm speaker to the board.
The firmware is written for the folder-p...
IR remote control based on an ATtiny13A powered by a CR2032 or LIR2032 coin cell battery. The code is a full implementation of the NEC protocol using only 370 bytes (36%) of program memory.
AVR ISP with buffer based on the design by ladyada.
Stand-alone High Voltage Serial Programmer and Fuse Resetter for ATtiny 13/25/45/85.

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...
