Single octave key board

Design and build a single octave keyboard using a breadboard. Not using anything like a raspberry pie. We might use such devices later in subsequent developments.

I know nothing about basic electronics.

Attached is a schematic. The sequence of events is that Key 1 is lit. When that key is depressed switched, the light to that key is extinguished, the sound for that key is emitted, and the light to the next key is switched on, and so forth through the octave.

The equipment must be capable of a convincing rendition of Close Encounters melody when amplified though a HiFi

In your bid for this work, please

1. Give your C.V. in electronics

2. Give a fixed price for the job.

3. Say how long it will take you to complete and send the drawings and prototype


Do not copy others in making unrealistically expensive bids. I am not offering this job in the UK or USA. Unrealistic bids tell me the person does not have sufficient experience to be awarded the contract.
