In this project, we'll learn not only how to create this device, but how to reverse engineer radio frequencies we know nothing about using RTL-SDR (a ~$14 software defined radio), as well as creating hardware and software using Arduino, the Adafruit FONA (GSM/SMS/2G board), an RF (radio frequency) transmitter to transmit custom signals, and even how to reverse engineer a proprietary radio signal we know nothing about!
