I have a 2 year old who really wants to add back up noises to his remote controlled dump truck.
I was thinking, as an electronics engineer, that I could tap into the power from the batteries and add some kind of circuit to make a little beep beep while in reverse. Then I thought there is probably already such a device on the market for real cars.although it probably runs off of 12 volts for a real car. This has 4 C cells in it. Anybody have any ideas for us as to how to make it go beep when it is in reverse? Thanks, David [Non-text portions of this message have been removed]
