A more complicated Circuit where you can adjust a potentiometer to change how fast the LEDs blink and as you can see from the picture below we had challenged ourselves to set up another LED for it.

for this circuit you would set up a LED that changes colors over time. very simple, not much more to say about it.

In this circuit we set up multiple LEDS to work at the same time. something you might notice is the potentiometer being added in the circuit even though it isn't supposed to. we set it up to be able to change each delay with the potentiometer and even add more time to the potentiometers set delay to make them different.

This is a circuit about using push buttons to change how the LED displays or if it is even on at all. its very simple and there's not much to it and a bit hard to modify so we didn't do anything to it. no video because I removed the wires too early and it didn't work even when put back in.

This is a circuit using photo resistors to change the LED by the amount of light. the LED gets darker the more light it is given and becomes brighter the less light it has. there is nothing else to it.

this circuit is a temperature sensor. it records the temperature around it and sends it to the computer for record keeping. there is no video because there is nothing to record.

This circuit is a servo, or a motor. it spins the motor at a certain rate and pattern. nothing else to say.

this circuit is a buzzer. when given the proper commands it can play a song or rhythm.
