Add a Teacher Note to share how you incorporated it into your lesson.

Step 1: Things You Will Need

2x 12k ,o, resistor
1x 731 ,o, resistor
1x npn transistor
Output(LED)
2x push buttons (or some input like arduino)
Jumper cables
9v battery and holder
Breadboard (or pcb)

Step 2:

Make a simple led circuit. The LED represents an output

Step 3:

Add a transistor an connect Collector to + and Emitter to ground as shown

Step 4:

Add buttons and connect them from the + terminal to the Base of the transistor with a 12k resistor for each button.
