MATLAB to PIC serial interface some code to let MATLAB talk to a PIC16f877 via the serial port. This isn’t that hard nor is it much code, but I spent a decent amount of time figuring it all out (starting from scratch), so I figured it would be helpful. Enjoy. Code with comments below is […]

3x3x3 LED Cube Here is my 3x3x3 LED Cube project. It runs using a PIC16F690. Along with the brief explanation of how to make it, I have also included the .asm file for the PIC and a piece of software written in VB.NET that you can create your own LED patterns. These can be exported […]

PIC development/testing board Here’s a PCB design for a bare bones PIC16F877 development board. All you need is a 4mhz crystal, two 22pf caps, one 4.7k resistor, and eight 470 ohm resistors, a 7805 regulator (not necessarily necessary, read below), and some LEDs (you don’t need to put all 33 LEDs on, just as many […]

DTMF Touch Tone Decoder Using Microchip PIC Microprocessor This project contains the details of using a Microchip PIC12F683 8 bit microprocessor to detect DTMF tones. The completed program allows the processor to be programmed with a string of DTMF tones to detect. If the programmed string is detected in the audio applied the audio input, […]

Use a PIC Microcontroller to Control a Hobby Servo This instructable describes how to integrate hobby servos (the kind used in RC planes, cars, etc.) into your microcontroller projects. How Servos are Different from Regular Motors In a regular DC motor, the amount of torque the motor exerts on the shaft is proportional to the […]

How to make a Clap-Clap on / Clap-Clap Off switch circuit! Hi all! This instructable not only gives the reader the information needed to create a clap-clap on/clap clap off switching circuit, but the logic used to make a hardware-only clap-on, clap off circuit.  More information on a hardware-only version can be found in the […]

DMX-512 RGB LED Wash Light Control Board A full featured driver board to control Red, Green, & Blue LEDs. When paired with the correct output board, it can control any arrangement of LEDs. Common Cathode, Common Anode, single color LEDs. From 1/8 watt LEDs to 3 watt LED arrangements. 4 stand-alone modes. Fade & Flash […]

Simple JDM PIC Programmer I have built this project to burn my small PIC’s This is a serial programmer works on the RS232 ( PC serial port ), known as JDM Programmer, thanks to the site http://pic16f84.hit.bg/ which contains the schematic and the programmer software. The programmer is powered from the Serial port itself, so […]

Intro: Mood vase I’m a fan of LEDs, lots of LEDs.  So here’s a slightly less crass way of using LEDs for decorative purposes. While this is by no means a neat and polished solution, and probably not the first of its kind, however the pulse effect is as far as I have seen unique, […]

48 Channel Mono / 16 Channel RGB LED Controller The 48 Channel Mono/16  Channel RGB LED Controller by Chromation Systems can be used to independantly control 48 groups/channels (up to 120ma per group) of mono-color LEDs or 16 groups/channels of common anode RGB LEDs. It utilizes 3x TLC5940 LED drivers controlled with a PIC 18F2550 […]
