I need a circuit that turns on an LED and plays a sound repeatedly when a button is pressed, and stops the sound and light as soon as the button is released. It needs to be battery operated, preferably by coin or button batteries.
The issue is that I need it to be very small (1.5cm x 2.5cm), and I can't find a programmable chip that small that has documentation. Is there a way to make a sound circuit that small?
