# TinyICOC - AVR In-Circuit Oscillator Calibrator
Sometimes AVRs are operated without an external clock. The internal oscillator does a good job in most applications, but when it comes to precise timing, its +/-10% accuracy is often insufficient. Fortunately, the oscillator can be calibrated, increasing its accuracy to +/-2% or better. There are a few ways to perform this manual calibration, but s...

<p>This project is a controller for three standard PC fans, controlled by a computer program(Windows 7/10 tested). Video with a demonstration:</p>
Схема простейшего вольтметра(скорее показометра) на микроконтроллере. Когда напишу прошивку выложу ссылку в описании.
Данная схема тестовая и по мере нахождения ошибок (в схеме или программных) они будут исправлятся.
TRUE RMS не измеряет.
This is my atmega8 (and ATmega328 compatible) development board.
As it has the uart connector, you can program it in the arduino ide, if you are into that. You just need to download the bootloader through isp programming.
(I personally prefer to do it the expert way)
I added some connectors according to what I usually use:
I2C (also pull ups)
SPI (with an extra pin for devices such as nrf24,...
so, I'm working on a project and decided it would be nice to have a small pcb for me to work on the communication between two atmega microcontrollers.
I designed as a very small development board with a UART connector to debug the RF24 communication but also so the whole board can be used as a shield, after.
My intentions are that, after I manage the RF stuff, I can use the board to input data...
