Serial Addressable RGB PWM LED Driver using PIC16F628A

Overview Ever since I made the serial controlled RGB LED PWM driver I've had many requests for an addressable driver.  Well I've finally got round to producing one.  The code is now completed and tested and the prototype boards are fully working. The design process behind this project was to enable anyone with a bit of electronics knowledge to build an array of cheap RGB LED drivers that they can control fr ...

Arduino powered temperature sensing RGB LED nightlight using PICaxe

About a year ago I started on a project to make a temperature controlled nightlight. I was inspired by seeing these lovely LED lamps styled as mushrooms growing out of pieces of wood. Those mushrooms were made out of glass, which was somewhat beyond my skills. However I then saw some had used translucent sculpey to make mushroom nightlights on instructables. So with that discovery it seemed like it would be ...

One-chip 11×10 LED matrix. using pic microcontroller

This project is pretty cool for a few reasons, and driving a huge LED matrix with a single 8-bit controller is just one of them. The idea was born when I bought 120 LEDs of the wrong type, and decided to do something with them. With that many LEDs, there are only a few things you can do, and a matrix is the natural first-place-winner in the competition of those ideas. One of the LEDs did not work, so a 12x1 ...

LED flasher using PIC16C84 Microcontroller

This is my first simple PIC program. It will flash an LED continuously at approximately 1Hz. It is a very simple loop that delays for 500 milliseconds (half a second) with the LED on, and then delays for 500ms with the LED off. Thus, the LED flashes at 1 Hz! The schematic for this circuit shows that the wiring is simple: connect a crystal oscillator across pins 15 and 16 and add the capacitors to ground. Wi ...

PIC Based Message wand

The project uses flashing LEDs to present shot message in the air by swinging a wand around above the head. A perfboard is used to construct the circuit that is powered by 2 coin cells type CR2016. The power fluctuations from excessive load on the coin cells can be prevented using the electrolytic capacitor. A toothbrush holder is used to make the message wand since swinging around the exposed sharp edges o ...

LEDactus using PIC18F1320 Microcontroller

The LEDactus is my version of a dry climate niche dweller like a cactus. LEDactus is immobile and attempts to survive by creating a pleasant display. This is of course in the hopes that passersby will be so entranced that they will build the LEDactus' progeny. Initial generations create a simple but pleasing display. Later generations attempt to produce more complex and mesmerizing displays. Finally, in the ...
