Components for Prototype 1

Circuit diagram for my project

For my components I did not need to use a multimeter to see the value of any of the components as they do not possess any. Here are all of my components.

Component list

Jumper wires. M to M and M to F

Used to connect the Arduino to the breadboard.

Breadboard

Allows for connects to be made on the breadboard in order to complete the circuit. A bigger breadboard allows for more electrical components. For mine specifically it requires space for 11 6mm pushbuttons.

Push buttons – 11 required for differet keys.

Push button 1 – C, Push button 2 – CD, Push button 3 – D etc.

Each key when pressed will correspond to a different note such as in a piano or keyboard.

Arduino Uno

Allows code to run through making it a programmable circuit board. When connected to a laptop, code may be uploaded via arduino.exe. When running the code, it will debug before allowing to upload into the Arduino. This ensures that you put down the correct code and desk check for any errors.

All the ports on the Arduino uno allow for connects to be made with the jumper wires.

Piezo speaker/buzzer.

Used for the audio output of the keyboard. When any pushbutton is pressed, a tone will play through the piezo speaker.

I however may change this component to a small 1w speaker in order to have a higher quality sound although it wont make much of a difference as each button will only play one tone or a dual tone at most.

Lets get started!

Now that all the components have been reviewed, It is time to begin assembling the circuit! Join me in my next blog for that.
