Hey, for a bigger art-project I want to build some wireless LEDs like here:
The LEDs (receiver) are simple, but the sender circuit is a bit much. I will need around 20-40 of the Senders and 100 Leds
Is it possible to replace the ESP32 with an i.e. 555 or something else? Would be nice if the circuit in the end is as simple as possible.
Also one more question, does someone know why they use a 40% mark to space ratio?
Is someone so kind and can help me with that? Thanks in advance.
