Things are moving along … With my new understanding of I2C master/slave communications, I’ve started work on larger arrays and finding the best way to manage the array and communicate the data to the host PC. Above is the latest iteration of the project… and here is a lengthy description of what you’re seeing: Along […]
I had purchased some huge (2″) 5×7 matrix a while ago, as part of my led sensor research. They’ve basically been banging around the lab since, getting pins bent and such. So this past weekend, I decided to put them to some other use. Their pin layout is sort of weird, it doesn’t match up

Hi friends, today we are going to make a four way traffic light controller using a PIC16F84 microcontroller. In this project we will operate three LEDs (RED, YELLOW, and GREEN) according to the traffic rules. Illumination of the green light allows traffic to proceed in the direction denoted, Illumination of the yellow light denoting, if

This project, called “Mini-Beacon”, is a miniature programmable LED Flasher that is based around the PIC microcontroller. This project grew out of an idea and recommendation posted on RunRyder.com. The Mini-Beacon basically simulates the light emitted from a rotating light beacon such as those used in older police cars and fire engines. As seen from the observer’s
Teddy nightlight multicolor A nice night light multicolor, ideal for baby’s room. For the realization I used: – Out of a pack of bubble bath for children in the shape of teddy bear – a nightlight with positive economic pressure – Complete circuit with a PIC16F84A (I was at home, but you can use any

Aurora 9×18 RGB LED art *** Check out my blog for updated version of this project and more! *** My obsession of LEDs has led me to this. Aurora 9×18 is a thing of beauty (if I can say so myself) – has 162 RGB-LEDs in a circular configuration. The color of each circle is

8×8 LED Array Multiplexed Infinity Mirror A little bit different than your regular Infinity Mirror. Using a piece of mirrored acrylic for the back mirror, 8 rows of 8 holes are drilled into in a grid pattern. A LED is then placed in each hole and wired up so that i can be multiplexed through

Aurora 9 bar – The Essence of Aurora Since the introduction of Aurora 9×18, I received many requests for the kits and PCBs. I’m still quite undecided about making those available for a few reasons. However I really want other LED lovers (ok that might sound too much to be able to build one themselves.

Project description: In this project, 8 LEDs are connected to PORT B of a PIC microcontroller. Also a push-button switch is connected to bit 0 of PORT A using a pull-up resistor.. When the switch is pressed the LEDs scroll to the right. Hardware: The circuit diagram of the project is shown in Figure 1.
