HI everyone, first post here!
I'm planning to build a 50+ addressable 10k ohms pots. the idea is like ws2812 leds, i could query for the value of any of this pots individually, with a 2 wire interface (there is physical space constraint, as a reason to do it like that, i can't use more than 4 wires, 2 for data, 2 for power & gnd, and i can't connect them individually).
my idea is to hook up each of them to a attiny13 (not using any other like attiny85, for the cost, the attiny13 is the cheapest avr i could find), and then write the code that will receive and send commands through this clock & data signal interface, in binary format.
is the first time i want to use this kind of communication protocol, so i was wondering if someone could share any link about it, mostly in the arduino IDE format.
