Simple application for switches and LED circuit

For this week’s lab circuits building I focused on 3 basic circuits:

  • LED connected to a power source

Similar to the lab example, I used an arduino to power the breadboard, connected the LED to a resistor and closed a circuit.

  • LED connected to a power source and controlled by a potentiometer

Similar to the lab example, I used an arduino to power the breadboard, connected the LED to a resistor and closed a circuit. I added a potentiometer to control the voltage that the LED receives. 

 

  • LED connected to a power source and controlled by a LDR (light dependent resistor)

Similar to the potentiometer example before this one, I used an arduino to power the breadboard, connected the LED to a resistor and closed a circuit. I added a LDR to control the voltage that the LED receives. once the circuit worked I built a small wood box to hold the two components together.

For the next itteration of this projects I’d like to invert the LDR sensor so it would light in the dark as opposed to light when bright.
