New ideas or a way to modify the old project
Unfortunately I didn’t manage to find any solution about the radio controller of the flying toy working only as a switch, so I have to, and forgive me for my play on words, switch idea.
Instead of having the toys fly when they receive the message from the radio controller, I will stop them, control them directly with the Arduino board and make something else fly. Another problem that I encountered is that the piezoelectric pad needs to be amplified to produce a sensible voltage signal change, and the value will only be read for fractions of seconds so the visible output will not be so spectacular.
So, what I thought is to use a microphone instead of the beating pads. Extract three different frequencies of the source spectrum, and drive three computer fans instead.
Let’s go back to work.
