We will use a 9v battery, two resistors, an LED, a switch and a transistor.<\/p>\n<p>The battery V1 provides 9v, this powers the circuit.<\/p>\n<p>Resistor R1 is used to limit the current to the LED, this is to prevent the LED from burning out.<\/p>\n<p>D1 is the LED, this is the light.<\/p>\n<p>Q1 is the transistor.<\/p>\n<p>Resistor R2 is used to limit the current to the transistor. Only a small current is needed to turn the transistor on.<\/p>\n<p>The switch SW1 is our manual control for the light.
