Little sister nose button contraption
IMPORTANT: DO NOT TOUCH THE RED AND BLACK WIRES TOGETHER!
The LED or transistor may burn out.
This project was inspired by the book Easy Electronics by Charles Platt in Experiment 5. It does not use any code.
1 3V battery supply
2 M-M Jumper wires
1 LED any colour
1 NPN 8050 transistor
2 people (children work best)
Each person holds 1 loose wire and 1 of the people squeezes or presses the other’s nose. The person is used not only as a button but also as a resistor so if you are going to add a proper button then don’t forget the resistor.
Follow the pictures to build the circuit.
