In a previous article I described how I designed the circuitry to control functions of the asparagus harvester. After bread boarding up a test circuit and doing some initial programming I decided a re-do was in order. I found I had a lot of unnecessary redundancy and I also decided to put the air regulation […]
Introduction Tired of spending hours and hours in wire soldering? Do your circuits look ugly and you are looking for a way to produce professional-like PCBs? Then you had better try photoetching. And the first step to do that is to have the right equipment that is an Automated Exposure Box. Moreover if you like

Introduction There are some 89Sxx development board, here is another one. I have designed this single side development board to be used as a tool for learning MCS-51 Microcontrollers, and for easy microcontroller project development. The 89Sxx development board features : 89Sxx 40-DIL based design, 89S51/52/53 In System Programming (ISP) through the 6-pin header RS-232

Here’s another breadboard module that carries a PIC16F628A microcontroller. The power supply pins and the I/O ports of the PIC16F628A microcontroller are accessed through male headers. It can be easily plugged into a breadboard and is very useful for quick prototyping. It frees up a lot of space on the breadboard since the oscillator, reset,

Built using a PIC16F84, about 4 hours worth of code and a few bits on a breadboard. This was the first time I’ve worked with PIC’s so it was a learning exercise. I started with the ‘Hello World’ microcontroller equivalent i.e. Blinking LED, then tried the ‘Knight Rider’ sequencing LEDs, and then hacked this together.

A long while back I posted a version of the schematic for the electronics for my project to build a GPS-steered parachute for rocket recovery. Since then I’ve tweaked the board a bit, to the point where the hardware design is clean and bug-free (as far as I know). So here is the current version

How to choose a MicroController It used to be that the number of different microcontroller chips available to the hobbyist was pretty limited. You got to use whatever you could manage to buy from the mail-order chip dealer, and that narrowed down the choice to a small number of chips. But times have changed. Digikey

“Ready for PIC“ is one of MikroElektronika‘s compact prototyping boards for 28 and 40 pin PIC microcontrollers. The board comes with PIC16F887 microcontroller which is preprogrammed with an UART bootloader firmware and thus eliminates the need of an external programmer. The on-board USB-UART module allows the serial data transfer between the PIC and a PC

Implementing ICSP requires connections to a minimum of 5 processor pins: VDD, VPP (also MCLR\), SCLK (on RB6), SDAT (on RB7), and GND. VDD and GND are straightforward. In most applications, it is best to dedicate RB6 and RB& for SCLK and SDAT. This avoids potential complications when these signals are used during programming. Microchip
