Need a very simple wireless two-way audio communication device.
i like to have a small device like a tiny headset, that is simple and has good range.
i wish to make this really cheap, under 200 INR.
mainly for audio communication (full duplex communication).
here, where i live, i don't have access to any good technology. i mean, i cant even get simple "variable capacitor".
so i have to purchase anything online, but the shipping rates itself to my place are too high for my budget.
i have seen circuits like "fm transmitter" but i need a "fm reciever" to pickup that signal. but fm recievers are hard to build.
i even made a fm transmitter( a very simple one), but it often switched the frequence, so i couldn't have a fixed frequency.
so i look for a circuit that is easy to tune and can be fixed frequency.
i came across this module "433Mhz RF Transmitter Module + Receiver Module Link Kit for Arduino"
but i done know anything about arduino.
if i can use this module to make a two-way voice communication, please guide me how to.
if not, please give me other ideas.
