Do you know the electronic referee flags? This system have two transmitters (the flags) and one receiver. Each transmitter (flag) only need one control command. When you press the button on the flag the receiver makes a buzz or beep.
Well I need to make or find an electronic circuit to make one pair of those flags. The range of the radio control circuit has to be at least 100/150 meters and the circuits have to be small and portable.
So, do you know any circuits or even projects similar to this? Any help is appreciated.
