Panic Button with attiny85 and RCSwitch 433Mhz module

thingiverse

I've built this panic button just for emergency, in my house i've set up a domotic system with arduino, basically this button send a 433 code that the base can receive and do whatever you need to do. it's battery operated with a 12v battery and a 220ohm resistor so the voltage for the circuit it's around 4.5v the attiny85 it's an "arduino" but for really simple operations, due to low memory available, it must be programmed with an arduino uno or 2009, i'll link the guide... https://create.arduino.cc/projecthub/arjun/programming-attiny85-with-arduino-uno-afb829 attiny85 as pwn pin on 0 and 1.
