How does the bi-color LED circuit workThe bi-color LED works like two LEDs connected at the short negative prongs making one prong that connects to the negative side, the two positive prongs connect to the positive side lighting up both LEDs.
About the NPN Circuit Pt 1When the NPN transistor's base is a switch that is controlled when electricity flows though it, this will close the circuit.
About the Pushbutton LED Circuitthe way the push button works is that when you push the button, it turns the open circuit into a closed circuit. when the button is NOT pushed, it isn't a closed circuit, so the LED doesn't turn on.
How the motor gearbox worksWhen the small gear turns all around it turns fast. The big gear turns slower, and turns only a little bit compared to the small gear. The use of small and bigger gears is how to slow down the speed of the wheels.
Capacitor leaks current as it chargesthink of a bucket of water .the fuller the bucket gets the less electric charge is let out. hence,at the begining the capacitor lets the LED light up towards the end , the capacitor starts to not let enough electricity flow.at the end the LED does'nt light up.
Understanding the Genius LightThe brighter the LED the more voltage is going through it not the photoresistor. This is the LED "path". The dimmer the LED the less voltage is going through it. Most of the voltage is going through the Photoresistor. This is the Photoresistor "path".
