DIY Led Blinking Project with BD139 Transistor & Potentiometer
Top LED Blinking Project with BD139 Transistor & Potentiometer
Components used in this project:-
1.BD139 Transistor
2.10K Potentiometer
3.100R Resistance
4.220uf/25V Capacitor
5.LED
Welcome to our step-by-step tutorial on building an engaging LED blinking project using the BD139 transistor and a potentiometer! In this comprehensive guide, we'll walk you through the entire process, from the necessary components to the wiring setup and coding, enabling you to create a fascinating LED blinking project effortlessly. Follow along and dive into the world of electronics with this exciting project!
This is the circuit diagram of this project.
Connect all components according to this circuit diagram.
Solder +ve pin of capacitor to Base pin of transistor
and solder -ve pin of capacitor to emmiter pin of the transistor as solder
Next we have to solder +ve pin of 2200uf capacitor to emmiter pin of the transistor as you can see in the picture.
Our circuit is completed.
So Now we have to connect input power supply wire to the circuit.
Connect +ve clip to Emmiter pin of Transistor and
Connect -ve clip to 1K resistor as you can see in the picture.
NOTE: We have to give 12V DC Input Power supply to this circuit.
Now LED will be flashing.
