I will be working on a simple yet robust intercom system from scratch. I will be using a ARM Micro Controller with ADC and PWM.
Ill try to update and show videos of it being tested as its available 🙂
It will be digital which means i will be able to add/remove rooms Might use a 16bit address which would mean… about > 60,000 rooms or areas can be covered. Might also add special codes for FLOORS and GLOBAL communication.
