This is an Automatic click mouse circuit. If you need occasionally clickable automatic mouse, use this circuit.
Materials
Normal USB Mouse, 555 timer ic, 300k ohm resistor, 3.9k ohm resistor, 1Mega ohm Variable Resistor,16V 100㎌ Electrolytic capacitor, 1N4007 Diode, DC 5V relay

◎ Cycle time = (300k ohm + 1Mega ohm + 3.9k ohm) * 100㎌ = (300,000 + 1,000,000 + 3,900) * 0.0001 = 130 seconds.
◎ Click time = 3.9k ohm * 100㎌ =3,900 * 0.0001 = 0.4 seconds.

But this circuit cycle time is about 100 seconds. Because the 100㎌ electrolytic capacitor extract from discarded electronics.
