Electronic Components




  • Positive DC terminal (higher voltage)
  • Thermistor (temperature dependent resistor)
  • Potentiometer (variable resistor)
  • LDR (light dependent resistor)
  • Resistor
  • Ground (lower voltage)












  • pin 13 of Arduino board
  • PWV (pulse modulated voltage)
  • isolating resistor
  • NPN transistor
  • ground (low voltage, not Arduino)
  • motor
  • battery +9V
  • voltage spike safety circuit
  • capacitor to store excess voltage
  • diode (one way flow) to drain excess voltage
