Status Closed

I am looking to have a working schematics of an electronic muscle stimulator modified. I am looking to add a 4 x 3 keypad to the current display board (This has already been started). I require the schematics to be done using the Proteus software. The current schematics is a fairly simple one, so it should not be too difficult to modify. In addition, I would like to have the chip (Atmel AT89C52 microcontroller) programed (using C preferable with kiel uVision) to make the machine perform its functions. I included a word document that explains how the machine functions within the file attachment. I have also included the old working schematics of the electronic muscle stimulator. **Only serious bidders may apply. Please look at all documents and files before bidding on this project. Technical Specifications of Schematics (Circuit): Input 24VDC/2A (power adapter) Outputs: Four isolated channels with individual intensity controls. Output Type: Medium Frequency: 2500Hz sine wave modulated at 50 beats per second. Output Current: 60 mA RMS into 500 Ohms Treatment Timer: 1-99 Minutes - in one minute steps Accuracy: +/- 1 second.
