Modern compatible microcontrollers are available from multiple vendors, in all shapes and sizes, and with a wide range of peripherals. Did you use this instructable in your classroom? Add a Teacher Note to share how you incorporated it into your lesson. This section will be brief, as I built my programming shield some time ago. I've attached the schematic and pictures of the assembled board. The PDF of the schematic can be found in the repository.

Fortunately, the programming protocol is simple, and I was able to make my own programmer based on an Arduino. View all 9 components. Arduino project file. View all 3 instructions.

An Arduino-based programmer for the AT89C2051 chip
It works from 2. The only tricky thing is that one pin has to be raised from the nominal operating voltage of five volts up to twelve volts during programming — the challenge was working out the easiest way to do this using an Arduino. So I decided to use an Arduino Mega for this project. A couple of zener diodes clip the voltage down to exactly 5V or 12V and a couple of transistors, also switched by the Arduino, select between either of those voltages or 0V to drive the pin on the chip. In the picture it looks like the chip to be programmed is soldered straight into the board, but of course in reality a ZIF socket is fitted in that position so that the chip s you are programming can be quickly swapped. If you want to etch your own PCB, here is a.
Arduino-based AT89C2051 programmer
A simple programmer for the Atmel AT89c microcontrollers. This is one of the simplest programmers. It was designed using common components, with respect to simple construction. It connects directly to a PC parallel port. Software is written in Pascal, the new version uses the Turbo Vision user interface. It should work with no problem on the first try. Both software versions support so-called DEBUG mode, that should greatly simplify any troubleshooting.
