Cheap and Simple Learning Board using AT89S51

Build your own a cheap simple Microcontroller learning board S-52. The board is based on ATMEL's new ISP chip AT89S51, AT89S52, or AT89S53. This board can be used by beginners for learning Assembly and C language programming. Single sided PCB file included.   Introduction I have designed this leaning board to be used as a tool for learning MCS-51 Microcontrollers. The AT89Sxx learning board features, D ...

The Prototino™ using ATmega168 microcontroller

What is a Prototino™?   The Prototino™ is an Arduino clone with a built in prototyping area.   Designed to make a permanent version of your project once you have perfected it on a breadboard but without the expense of embedding your original Arduino into your project. The Prototino also makes your project more reliable and robust. With the prototyping area integrated into the board with the microp ...

ATtiny breadboard headers using ATtiny2313

These tiny controller boards are build to provide a quick start for projects with 8 and 20 pin AVR microcontrollers, e.g. ATtiny13, ATtiny45, ATtiny85 and ATtiny2313. They don’t include any fancy stuff, they are just as simple as possible. Where is the problem? Whenever I was prototyping on a breadboard I was annoyed by all the wires to setup before the actual project could begin. Arduino projects were much ...

Minimalist Arduino using ATMega328P microcontroller

Overview Here at the Transistor, we love the Arduino platform, so we decided to make our own Arduino Clone. The Minimalist Arduino is designed for use in permanent or custom circuits on solderless breadboards, stripboard, or custom PCBs. It contains only the bare minimum parts required for building the Arduino platform. The schematic for the board can be downloaded here (pdf). Please read all instructions o ...

Project Development Board using ATTiny2313 microcontroller

This is my first time using the AVR. I like to learn using the ATTiny 2313, because it is faster than MCS-51, cheap and the circuit is very simple. The chip has only 20 pins. I was interested because I want to build a simple line follower robot controlled by this MCU. Board Construction The circuit has built in voltage regulator, the LM7805 and the ISP Header for program loading. The DC input circuit also h ...

PS/2 to C64 Mouse Adapter using ATmega8 microcontroller

A pixel artist friend of mine wanted a mouse to try his skills on a real C64. I thought I could help him by making an adapter that would allow a regular PS/2 mouse to be used with a Commodore 64. The most popular and supported C64 mouse is 1351 mouse which uses analog capabilities of joystick control ports to send movement data. Same mouse also has a joystick compatibility mode that emulates joystick tilt i ...
