89Sxx Development Board using microcontroller

Introduction of 89Sxx 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 and RS-485 serial port (share ...

AVR ATmega8 Project LED Moving Message Display using ATmega8 microcontroller

An interesting project that can be done using Microcontroller is a LED message scroll er. It teaches you a quite lot of things. So I decided to make one. I made the hardware design modular and cascadeble That means the whole display is made up of several 15x7 modules. Each module has everything to drive 15x7 led matrix which includes a ULN2003 row driver IC and two shift register IC to drive the 15 columns. ...

Easy Breadboarding using ATMega microcontroller

When I'm fiddling about with electronics I want to be comfortable about it. Therefore I built some things to make by breadboarding life a little simpler. One example is the Network Breadboard Interface. Another one is this little project. These little pcb's can be put directly into a breadboard and they have the same pinout as the AVR it is designed for. Each of these circuits also has a 74HC4053 and a prog ...

Experimental board using ATTiny2313 microcontroller

This is an experimental board for ATTiny2313 microcontroller that provides a 10-pin connector for in-circuit serial programming, and other header pins to access I/O pins. The AT2313 microcontroller runs on an external 10Mhz crystal. The board has a push button reset switch for resetting the microcontroller. The onboard regulator provides a +5V DC to the microcontroller. The board is also featured with a DB9 ...

Development Board With LCD using Atmega16 microcontrollers

This instructable shows, how to do your own development board for Atmega16 or Atmega32 processors.The Internet is full of home made development boards, but I think that, there is room left for another one. This board have been very useful on my projects and I actually designed and made it to serve one of my project. What it offers? - ISP-connector. - Adjustable reference voltage for AREF with trimmer. - 8 l ...

An universal programming adapter for the Atmel STK500 using AVR microcontroller

You have an STK500 development board for the AVR controllers from Atmel? And you want to use it with a newer AVR controller which is not supported by any of the 8 sockets on board? And you do not own an STK505 extension board? Welcome to my world until yesterday! This is my first instructable which will describe how I helped myself yesterday. You might find an update on my blog as well... Step: 1 What you n ...

Garduino: Gardening + Arduino

Garduino is a gardening Arduino. So far, Garduino: -Waters my plants whenever their soil moisture level drops below a predefined value. -Turns on grow lights, but only when it's dark out and only long enough to make the plants get 15 hours of total light (sunlight + supplemental light) daily. -Alerts me if the temperature around the plants drops below 50 degrees. This is the first grow-light and auto-water ...
