ATMega168 / 328 as a wireless 433MHz temperature sensor.
ATMEGA168:
Flash to atmega168, connect 433 MHz TX to output PC2 - receive with rtl_433 (github.com/merbanan/rtl_433) or compatible WH2 weather station
this is just a proof of concept, it can push valid packets from an ATMega168 to a receiver, you need to connect a temperature sensor
do readings and modify the variables accordingly.
ATMEGA328:
Flash to atmega328, connect 433 MHz TX to output PD7 - receive with rtl_433 (github.com/merbanan/rtl_433) or compatible WH2 weather station
this is just a proof of concept, it can push valid packets from an ATMega168 to a receiver, you need to connect a temperature sensor
do readings and modify the variables accordingly.
bitwise.c was used for testing bit shifting without having to flash the atmega eeprom every time
