Question: Design using proteus, a microprocessor based scanner which will scan a black and white image and store it as binary data.

The scanner has two stepper motors for motion along two orthogonal coordinates.

The rotational motion is converted into transnational motion through a lead-screw mechanism.

Five paired LED photodiodes intended for B&W image scanning are placed 0.1 centimeter apart.

The maximum size scannable is 10cm X 10cm.

The photodiode output is analog signal (between 0 to 5 Volts) which is to be digitized.

Image information is stored sequentially in the RAM.

The user presses a switch labelled Start Scan when he wants to scanning process to be completed.
Once scanning is completed an LED labelled Scan Complete I will glow.
