Lesson Outline
Brightness of a LED - 15 minutes
- Make a LED circuit using the potentiometer to control the brightness of a LED when you change the position of the potentiometer.
Tuning ON and OFF the LED - 15 minutes
- Make a LED circuit using the switch to control the state of the LED, where when you press the switch the LED will glow and when you release the switch it stops glowing.
Assignment - 30 minutes
- Let students make a LED circuit, where they will control the brightness and the state of the LED simultaneously using potentiometer and switch.
