This circuit shows the charge of a capacitor checking the state of this one.
The diverter in its left position charges the capacitor.
Instead, this one in its right position, or the button, discharges the capacitor.
The three leds (red, yellow and green) check the state of the charge.
If the red led is on, the capacitor isn't charging.
If the yellow one is on, the capacitor is charging.
If the green one is on, the capacitor is succesfully charged.
This is the second version of the circuit.
Infact this one has another relay used to stop current flowing in the capacitor whenever is completely charged.
