There is the project I’m going to give to my two years old son this Christmas. He like playing with all kinds of buttons he found everywhere. But they almost done nothing for him, except the ones on my dryer. So I decided to give him an experience box made of many kinds of button that take different action on lights and a motor.
There are only three little electronic circuits in the box. The rest is only wiring. One circuit is a flip flop to make the two red leds flashes and the other one is an And Gate to make the two arcade button light up the yellow led only when the two button are pressed, the last one is a bicycle flash hacked to fit the panic button.
There are nothing much more to explain about this box, the pictures and the video will tell you all.
