Circuit Documentation

Summary of the Circuit

This circuit is a simple pushbutton-controlled LED circuit powered by a 4 x AAA battery mount. When the pushbutton is pressed, the circuit is completed, allowing current to flow from the battery through a resistor and the LED, causing the LED to light up. The resistor is used to limit the current to a safe level for the LED.

Component List

LED: Two Pin (red)

  • Description: A red LED with two pins: anode and cathode.
  • Purpose: To emit light when current flows through it.

Resistor

  • Description: A passive two-terminal electrical component that implements electrical resistance as a circuit element.
  • Properties:
    • Resistance: 200 Ohms
  • Purpose: To limit the current flowing through the LED to prevent damage.

Pushbutton

  • Description: A simple switch mechanism for controlling some aspect of a machine or a process. It has four pins: two for the input and two for the output.
  • Purpose: To allow the user to control the flow of current in the circuit.

4 x AAA Battery Mount

  • Description: A battery mount for holding four AAA batteries, providing a power source for the circuit.
  • Purpose: To supply electrical power to the circuit.
