Pulsing Hubby Detector This project uses an RF receiver module to trigger a pulsing LED Heart when the transmitter comes within range. I made this for my fiance for Valentine’s Day this year. I have yet to fully test the range, as I haven’t actually taken the transmitter out of our apartment building since I […]

I have built various scrolling message badges for instance using the 16F57- 10×5 and 12×5. However, since these chips only have a small FLASH, there is not much flexibility. I don’t really recommend these controllers for a scrolling message. Recently I have started a new project, using small 1.9mm ready made modules, and a 16F884.

Introduction I’ve always wanted to build an electronic led dice, but something different from what we see on the internet. Making it motion controlled… now that’s new! Many new cell phones that have accelerometers built in also have dice games. These dice move when shaking the cell phone. My Led Dice project will

The photo shows a PIC16F84 microprocessor board tethered, by ribbon cable, to a circuit having 8 LEDs and an 8-position DIP switch. Learning a microprocessor’s capabilities often demands such a setup where LEDs turn on/off, blink at desired rates and respond to switches. This tutorial serves to quickly accelerate your PIC16F84 development ambitions. Motivation and

I had a few multicolor LEDs laying around and wanted to whip up a color-blending nightlight. I built 2 devices, each in its own 20 pin DIP socket without soldering. A 3-pin header is included so I can reprogram the light on-the-fly if desired. On my first build, I used wire-wrap. The next one used

Using a single super-power LED – 1,400 lm, emitting at 200Mcd/m2 – Osram has produced a dip headlight beam in its labs. The distribution of light indicates that car lighting standards can be met – see candela plot. “This LED has a luminance three times that of existing versions. This means that a single LED

Anthony from Cumaná, Venezuela, made his own “Persistence of vision” (POV) display, similar to my Air Display but it can be mounted on any bicycle wheels and it displays fifteen messages in Spanish. Here is the PCB with each part of the project. It uses a 12F629, works with a voltage of 3Volts This is
Hi welcome to my 4th chapter of PIC18F4550 programming. Here we are going to learn another methodology or technique for programming a pic18f microcontroller which would be helpful in future while dealing with complex coding. We are going to define our own header file. We are also going to see the Source Code and will
