Inexpensive microcontrollers have seen a resurgence thanks to the internet of things (IoT) and wearable devices. These end-uses depend on parts that have low costs rather than record-breaking speed. Because of this, devices like the Atmel AVR series have enjoyed decades of popularity. Any software we develop for these devices eventually needs to go from

This is my first AVR-project on this page. The DiSEqC-Tester allows to test DiSEqC-switches that uses 1.0 or 1.1 protocols. (DiSEqC-Switches with 2.0 and 2.1 protocol have backwards compatibility with 1.0 & 1.1 respectively and also may be tested). The device every second sends a DiSEqC-message that makes switch a DiSEqC-switch. Four LEDs are intended
