 This is a firmware for ATtiny2313 and ATtiny26 target (slave) devices that enables you to control up to 10 servo motors by a controller (master) device via I2C.

 ### Example and demonstration
 
-I used Stefan's code for my [WeFish fischertechnik controller](https://forum.ftcommunity.de/viewtopic.php?f=33&t=6359) system, which is build around the Wemos D1 mini and compatibles. For the servo module , the ubiquitous PCA9685 modules would have been too big, while a bare ATtiny2313 with two capacitors was a natural fit (the servo module is in the middle):
