DIY granular synthersizer

This is my first DIY synthersizer project.
It's based on the code by Peter Knight.

It's a simple synth, a great first project to start building synthersizers.

How to start

Skills needed:

• Basic knowledge of Arduino programming
• Basic knowledge of electronics
• Basic soldering skills

Parts:

• 1x Arduino nano
• 6x potmeters, 5KΩ
• 1x resistor, 470Ω
• 1x led (power indicator)
• 1x DC connector
• Power adapter, 9V will be fine (Arduino nano 7-12V is recommended)
• 1x jack or mini jack connector
• 1x small universal circuit board
• 2x 15-pin female header, to use as a socket for the Arduino
• wire

Tools:

• soldering station
• soldering lead
• pliers to cut wire
• breadboard
• jumper wires
• usb cable to connect your arduino to your pc
• small speaker
• Arduino IDE

Download the Bzzz arduino code. Build the code with the Arduino IDE and upload it to your arduino nano.

Testing

First test the code on a breadboard. Use the diagram below to connect the wires. Don't connect the + Vin and - GND to a power adapter when you using the usb cable to connect your Arduino.

• P1 Potmeter 1 controls grain 1
• P2 Potmeter 2 controls decay 2
• P3 Potmeter 3 controls decay 1
• P4 Potmeter 4 controls grain 2
• P5 Potmeter 5 controls the note played
• P6 Potmeter 6 volume
• R resistor to protect the led
• LED power indicator
• S speaker, replace with a jack connector in the final build

If all seem to work then start soldering the parts...

Be carefull connecting the power connector, check the polarity of the power supply used!

or

Connected wrong you will damage your Arduino!!!

Making a casing

Just use your imagination :)
