Introduction: Simple LED Flip-Flop for Beginners
A very simple Flip-Flop circut for beginners
Step 1: Parts List
- LED X2
- Resistor: 10K (brown-black-red) X2
- Electrolytic capacitor: 100uF X2
- Transistor: NPN like BC108 X2
- 9V Battery with connector
- Striped wire
- Spongebob assistant (optional)
Step 2: Resistors
1K : Brown - Black - Red
10K: Brown - Black - Orange
Put resistors on the breadboard like pictures.
Step 3: LED
Put LEDs on the breadboard like pictures.
Notice to polarity of LEDs
Step 4: Capacitors
Put capacotrs on the breadboard like pictures.
Polarity is not very important
Step 5: Transistors
Put transistors on the breadboard like pictures
Step 6: Wiring
Connect point 5 to 11
Connect point 6 to 8
Connect point 2 to 9
Connect point 4 to 12
Connect point 7 to 10
Step 7: Battery
connect + to point 13
connect - to point 10
You can use 3V to 9V battery
Step 8: Run
You can use larger capacitors (like 470uf) for slower flashing and smaller (like 47uf or 10uf) for faster flashing.
Use a larger capacitor (like 470uf) for slower,or a smaller one (like 47uf or 10uf)for a faster blinking.
Step 9: Refrence
