Summary of PIC12F675 RGB LED DRIVE CIRCUIT
This article describes a PIC12F675-based RGB LED drive circuit. The project uses a microcontroller to control color transitions via PWM on 12V LED strips. While the PIC12F675 is used, the author notes that the PIC12F683 is preferred due to better memory for smooth visual transitions. The circuit employs MOSFET transistors to drive the LEDs and can support strip lengths of 20 to 30 meters depending on the MOSFET selection.
Parts used in the PIC12F675 RGB LED Drive Circuit:
- PIC12F675 Microcontroller
- PIC12F683 Microcontroller (Recommended alternative)
- MOSFET Transistors
- 12V External Power Supply
- RGB LED Strips
- BC237 Transistor (for small lampshades)

We constantly work places which attracts lighting with RGB LEDs that are encountered in a variety of colors created by the transition to the visual feast that may be just a small sample of drivers I share with you are interested. The project is definitely not a product for the purpose of example only write and publish it.
You develop software products can make. Indeed, in the market to make money with this project seriously if possible to offer a product that reason, I find it appropriate.
Project 12f 675 or 683 to be used is written with PIC mosfet transistors plowed an external supply strip with LEDs (12V) to be fed programmatically PWM gradations of color toning is made. (12f675 hardware PWM having is not therefore programmatically PWM is used)
Note: Visuality 675 memory is not sufficient to improve the final version of the project for the 683 I’ve used it and transitions as required is provided in a very pleasant way.
RGB LED DRIVE CIRCUIT TEST
I use strips with RGB LEDs from 20 to 30 meters in length will flow is calculated. Mosfet will use the length can be increased. 237 BC in the accompanying video applications, and I use it a few LEDs for small lampshades easily spreadable.

- Why is the PIC12F683 recommended over the PIC12F675?
The PIC12F675 lacks sufficient memory for the final version, whereas the PIC12F683 provides smoother transitions. - How does the circuit control color toning?
It uses programmatically generated PWM gradations to create color transitions. - What voltage supply is required for the LED strips?
The project requires an external 12V power supply to feed the LED strips. - Can this circuit handle long LED strip lengths?
Yes, it supports strips from 20 to 30 meters in length, with capacity increasing based on the MOSFET used. - Does the PIC12F675 have hardware PWM?
No, the PIC12F675 does not have hardware PWM, so the project uses programmatically generated PWM. - What component is suitable for small lampshades?
The BC237 transistor is used for spreading light easily on small lampshades with a few LEDs. - Is this project intended as a commercial product?
The author states it is an example project, though they believe it could be developed into a money-making product.
