This is a multifunction bench test instrument built using an Atmega128 microcontroller and incorporate a lot of functions like voltmeter, ammeter, logic analyzer, frequency generator, frequency counter and also provides regulated DC power supply.

Perhaps one of the most entertaining things to do with an embedded microcontroller is to get it to actually move something. Three very popular devices used to “make things move” include dc motors, RC servos, and stepper motors. This lab session will look at how you can interface a dc motor to a PIC microcontroller.

Programming microcontrollers isn’t hard. Building a programmer makes a great first electronics project. The goal of this instructable is to explain the simple ‘in circuit serial programming’ method used with Microchip PICs.

ZF did a review of the FTDI Vinculum board: [via]

I just got hold of FTDI chip’s new Vinculo developing platform, so here’s a quick review for you!

Vinculo is a 25€ development platform for the FTDI Vinculum II (VNC2) dual USB host/slave microcontroller. The board design has been copied from Arduino, and they even advertise it as Arduino-inspired and Arduino shield compatible. FTDI seems to have realized the potential that comes when having a large hobbyist userbase…

Programming AVR microcontrollers using ISP is a simple process when the target is on a board exposing a 6 or 10-pin ISP header. But what if you have different types of AVR chips? Their SPI pins (VCC, GND, MOSI, MISO, SCK) aren’t always in the same locations.

Instead of buying different types of target boards or buying an expensive generic programmer, I built one using a small breadboard, a Universal 28 pin ZIF DIP socket and 6 male-male hookup wires that I connected to my USBtinyISP programmer.

This article explains some of the updates to some of the most mature microcontroller architectures. [via]

60% of all CPUs and MPUs are 8 bits; 16 bitters account for 15% of the market, with the much ballyhooed 32 bit machines bringing up the rear of the market at a paltry 9%. According to a 2001 survey, our 43% of our readers use PICmicro parts, 55% use 8051/52/251/AVR, 36% go for Motorola’s 68XX family and Zilog’s Z8/Z80/Z180 devices account for about 15%. These numbers total more than 100% as some folks used more than one processor in that year. In the 16 bit world 41% use 8086/186/96/196 devices and 21% employ the 68HC12/16.

Embedded-Lab has launched a tutorial on interfacing a DC motor with a PIC microcontroller. It describes about the various operating modes of a dc motor and how to control them with a microcontroller. The tutorial also describes a classical H-bridge circuit using transistors.

This article discuss about mcu software and what to do when your code grows in size. We should follow some simple rules that makes microcontroller programming more fun than scratching along. Check details on the link below.

Pinguino is an Arduino-like board based on a PIC Microcontroller. The goal of this project is to build an integrated IDE easy to use on LINUX, WINDOWS and MAC OS X. This is a simple 40 pin PIC development board as described in RadCom for November 2009. It is designed for a PIC18F4550, but it will work with other 40 pin PICs like the PIC16F877A. It has no bells & whistles attached. No buttons, LED, LCD ICSP etc. All of the PIC pins are easily accessible so that you can add any features you need. This board has been tested with the Vasco PUF and the Pinguino USB bootloaders.

Building something cool from scratch is one of the greatest joys for the NerdKits team. With the holiday season approaching, we thought it would be awesome to automate a musical instrument that we could control with a microcontroller, and have it play Christmas carols. Keeping true with the NerdKits spirit, we decided to build a xylophone, build the whole thing from scratch including homemade bars and solenoids, and cover some interesting new concepts along the way!

In the video tutorial we not only document how we built the robotic xylophone, but we also cover solenoids, vibration modes on a bar, a little bit of the theory of electromagnets, and even digital shift registers! As always, we explain the concepts behind the project as well as provide the source code so you can work these ideas into your own projects.
