Embedded ethernet enables microcontroller based projects to send and receive packets over the network. The board shown on the left is actual size and incorporates all the circuitry needed to enable 10BaseT communications. The board is designed to minimize the pin count needed to interface with microcontrollers. An 8 bit data bus, 4 bit address […]

Introduction to the PIC32 using pic-microcontroller
The Microchip PIC32 is a family of complex and powerful microcontrollers that can be purchased for less than $10 in quantities of one. This microcontroller offers many peripherals useful for mechatronics purposes, such as several channels for analog-to-digital conversion, digital I/O, synchronous and asynchronous serial communication, pulse width modulation, etc. For our purposes, the primary […]
STEAM GENERATOR using PIC16F873
Introduction This program is a steam generator controller that is intended for use in a residential steam shower. It controls water inlet and drain valves, power to the heating element, and various level and thermal sensors. Features Push button automated control of the steam shower. High and low steam rates, extendable cycles, error conditions are […]
Building the Mongoose Mechatronics Robot: Part 1 Chassis & Gearbox using PIC18F2525
Building the Mongoose Mechatronics Robot: Part 1 Chassis & Gearbox This is the first of a series of illustrated instructions for assembling the Mongoose Robot kit available from blueroomelectronics Mongoose highlights: Powerful PIC18F2525 microcontroller (32KHz to 32MHz) Hardware PWM controlled SN754410 H-Bridge with thermal shutdown Differential drive with powerful 114.75:1 gearbox Low drag steel ball […]
Open Automaton Project
The objective is to use readily available “off-the-shelf” low-cost consumer components where possible, and to design electronic subsystems where such components are either not readily available or are too expensive. In terms of affordability, the overall goal is to design a robot that can be made for around the price of a PC (US$1,500 to […]
RGB LED PWM Driver for High Power 350mA LEDs V3 using PIC12F629
Description As featured in Electronics Weekly Gadget Freak (20/02/2008) The main reason I made this version is that I wanted to fit it in to the base of an Ikea Mylonit lamp. This lamp is made entirely from glass and has a small recess in the base with an entry for the power lead. Since […]
LED fireflies prototype using PIC12f683 microcontroller
LED fireflies prototype hello all, heres an attempt i made at something like an LED throwie..the problem (for me) with led throwies is that they just consume their battery, and produce light.. but they could be better at doing both.. first you have to accept the premise that your willing to spend a bit more […]
PIC’ing the MAX5581: Interfacing a PIC Microcontroller with the MAX5581 Fast-Settling DAC
MAX5581 Overview The MAX5581 is a 12-bit, fast-settling DAC featuring a 3-wire SPI™ serial interface. The MAX5581’s interface can support SPI up to 20MHz with a maximum settling time of 3µs. This application note presents an application circuit and all the firmware required to interface the fastest line of PIC microcontrollers (PIC18F core) to the […]
IR(infrared) Remote Control Relay Board with PIC 12F675 Microcontroller
Introduction This little project will demonstrate how you can use your old NEC IR protocol based TV,DVD or VCR remote control to control you home appliances like fan bulb or virtually anything. Consumer IR protocols There are a number of consumer Infrared protocols out there and they have been used for every single purpose possible i guess, like […]
Programmable watch with four character display using PIC16F628A microcontroller
Programmable watch with four character display You’ll be the talk of the town when you wear this obnoxious, oversized, completely impractical wristwatch. Display your favourite foul language, song lyrics, prime numbers, etc. Inspired by the Microreader kit, I decided to make a giant watch using similar sixteen segment displays. Twelve hours later, I came out […]
