Remote Radio Control Circuits
Technical Help?? Remote control Cars!?
I am a year 10 student doing a G.C.S.E technology project at school. My project is to build a T.V remote holder with a system to find the T.V remotes if they are lost. As part of my project, i plan to embed a transmitter and receiver device from a Radio Controlled Car into my design. I want to basically replace the motor in the circuit board of the RC Car with a buzzer so that when i move the stick on the controller up, the buzzer sounds. I will then clip the circuit board of the RC Car to the back of the T.V Remote. I have to cut the circuit board down in size so that i can clip it to the back of the remote with a buzzer. Have you any ideas as to what i could do? Thank you very much for your time and help.
RC cars usually use a SERVO system to engage power to the drive motor.
Keep the servo, but exchange the motor for a Buzzer, simple, but a very expensive way of doing it.
A much cheaper way would to be to not use the (multi channel) R/C circuits from a car, but something simple like a digital, singe channel TX/RX circuit like ….
