I am working on a project that uses an Arduino Uno R3 and will have one receiver and one transmitter. I'm going to use this for home automation within my home in India. I want to know which transceiver would be better, a 2.4 GHz or 434 MHz module? My requirement is a 100 meter range.
Also, I would like to know if I can use an ATTiny along with the transmitter?
