Hi guys, I have a simple question regarding a cheap tx rx for arduino.
So Im building a heating glove that heats up at certain intervals (ex. 1 sec ON, 5 sec OFF). Since the circuit will sit on my wrist, dimensions are very important.
I want to use 2 gloves, but I also want one to be the “master” (this will be the one I use to change the heating intervals, with OLED+buttons) and a “slave” (only for receiving the intervals and executing them on the second glove).
Also, I noticed that cheap tx and rx only have 3 pins, Vcc, Gnd and Data. I would assume that the Data pin works by outputting high and low voltages to communicate with the arduino.
Based on this assumption, my question is, can I use a rx on the slave glove WITHOUT a 2nd arduino? (to do this I would connect the data pin to the Gate of the N Mosfet, and make it go HIGH for how long the interval is). Is my reasoning wrong?
Thanks for taking the time to read through all this ;)
