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
How to start
- Basic knowledge of Arduino programming
- Basic knowledge of electronics
- Basic soldering skills
- 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
- 1x jack or mini jack connector
- 1x small universal circuit board
- 2x 15-pin female header, to use as a socket for the Arduino
- soldering station
- soldering lead
- pliers to cut wire
- 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.
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!
Connected wrong you will damage your Arduino!!!
Making a casing
Just use your imagination :)
