Hi all,
I am a beginner to arduino trying to transfer data through LASER in arduino.but I couldn't read the transfered String and i am getting garbage values.I am using photodiode on the receiver side to detect the transmitted signal.I have connected the LASER and photodiode to Tx and Rx of two arduinos respectively.Should I use any modulation algorithms to transfer the data through LASER?? or Can it be transfered simply through Tx without any modulation??? Plz help me out
