It's my first time working with wireless and Arduino, and it's proving to be quite a challenge! Upon wiring everything and uploading sample software, my receiver is not getting anything at all. Namely the ATtiny13, or other ATtiny chips. Operating mode: AM 5. The transmitter circuit comprises of an Arduino, the DHT22 temperature and humidity sensor, and the 433 MHz RF transmitter module. Open ARDUINO IDE and install the RF24 library for nrf24l01+ module . The transmitter/receiver (Tx/Rx) pair operates at a frequency of 433 MHz. Receiver Code (8 pin module) Pin 2 of your Arduino should connect to pin 2 of your RF Link Receiver 434MHz. The only way I can see you can do this is make some type of protocol where you send data with a station ID and only the receiver with the station ID matching the message will act on it. dz ya fk yq ey ws ez fs ec gp
