If you always want to show some special flashing effect of your name then this one project is only for you. Here I made the LED board for flashing a name “MANAH” with a cheap PIC microcontroller based circuit so that this project prepared for a low cost but highly effective.
Step 1: Required Components
- Microcontroller PIC16F675
- NPN Transistor TIP120/TIP122 X 5
- Resistor 1kΩ X5
- Resistor 220Ω X5
- Capacitor 220μF/16V
- 8-Pin IC base
- SMPS Board for DC 5V power supply
- Any suitable Programmer like PICkit2/PICkit3.
Step 2: Circuit Diagram
For the word ‘MANAH’ it is a 5-channel based circuit and for each I used approximately 100 LEDs per channel but in the circuit, only 3-3 LEDs per channel are shown for reducing the image size.
Step 3: Programming & Source Code
If your name is of different size then you just need to edit the program written with a compiler “Mikro C for PIC” and download the complete code. Finally burn the generated HEX code to the to the microcontroller using a suitable PIC programmer like PICkit.
