Panic Button with attiny85 and RCSwitch 433Mhz module

thingiverse

I've built this panic button for emergency situations, with a domotic system set up in my house using Arduino. The button sends a 433 code that the base can receive and do whatever is needed. It's battery operated with a 12v battery and a 220ohm resistor, so the voltage for the circuit is around 4.5v. The Attiny85 is 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 has pins on 0 and 1.
