So now we have a powered breadboard, disconnect the power (important) and connect up a LED (Light Emitting Diode) and a resistor in SERIES.
An LED is like a bulb, but one way, the short lead goes towards the ground. As long as the resistor is in series, it can be before or after the LED.
NOTE ABOUT COMPONENTS
- Resistor value should be fine at 220 ohms or even 330 ohms if supply is 3V.
- The switch needs to be wired up properly, diagram is a guide, it depends on the switch you use.
- Experimentation is key
- If you require help, please ask an adult.
