Networking with PIC 18Fs + ENC28J60

Posted February 4, 2015 by Chris

"It takes just few components to get the ENC28J60 up and running and connected to a host microprocessor or microcontroller with support for the industry standard SPI interface. This project includes the schematics and related information for a simple hardware implementation based on the ENC28J60 (ENC) and a Microchip PIC18F 8-bit microcontroller running Microchip’s free TCP/IP stack."

Christmas Lights With Individual LED Control

Posted December 18, 2014 by Chris

"I wanted to create a truly personalized one without ruin me either. Two ideas immediately came: a microprocessor to control all the lights, but at the cost of a relatively large strand wire, even though the use of crossing wire and diodes, can reduce the number of son, this is not very satisfactory and place a microprocessor per lamp, but until the price of each processor exploded the price of the most basic garlands."

Christmas Lantern Synchronized with music

Posted December 11, 2014 by Chris

"The project was a 5 ft tall lantern composed merely of junk wires, light bulbs and considerable amount of electronic components. The lantern was synchronized with monotone tunes. There were 5 different songs used and every song has different light sequences."

Infrared IR Sensor Interface with PIC18F4550

Posted November 22, 2014 by Chris

"In this project, as promised before – we are going to demonstrate a PIC18F4550 microcontroller interface to IR sensor circuit….however you can do some more intelligent operations by adding some more logics to the microcontroller coding. Interfacing infrared Proximity sensors with Microcontroller is quiet easy."

14×5 LED dot matrix scrolling message + source code

Posted November 14, 2014 by Chris

"The font is proportional, most characters are 4 pixels wide, some are 3 only, and a few are 5 pixels wide. The complete bitmap is precomputed, which requires a large RAM buffer."

Picture-Axe, Sound trigger to camera flash

Posted September 29, 2014 by Chris

"Sound seemed to be the logical choice, and google led me to some basic circuits for triggering flashes with sound, but I wanted to be able to control the delay and sensitivity and have different modes and functions. Thanks to LMR I new the solution. Microcontroller! So I started boarding and building."

RFM12 – Wireless Transceiver Module Demo

Posted September 16, 2014 by Chris

"This project shows how to do wireless communication with the RFM12 tranceiver modue in combination with a PIC microcontroller. The RFM12 is a low costing ISM band FSK transceiver module. There are different module variants available which support different frequency bands: 315/433/868/915MHZ."

Open Source Framework for USB Generic HID devices using PIC18F

Posted September 11, 2014 by Chris

"I’ve developed a framework for producing USB devices which covers both the Windows host-side application development and the PIC18F firmware itself. The framework consists of a Visual Studio C# class library, a windows reference application, a simple USB hardware reference design and a PIC18F4550 firmware which communicates with the class library."

PIC Propeller Display On A Breadboard

Posted August 13, 2014 by Chris

"This is my first post Related to Projects and today I will describe Propeller Display project. Me and my friend Rushi, we both made Propeller Display project during our under-graduation…The project uses Microchip PIC16F84A Microcontroller."

HID QuickKey USB Adapter

Posted August 8, 2014 by Chris

"The hardware is based on Microchip’s Low Pin Count USB Development Kit for the 1814K50. It is setup with 10 inputs, each with a pull-up resistor. The firmware is programmed with USB Human Interface Device Keyboard example from Microchip Solutions. It requires no drivers or special setup, it is plug and play."
