Arduino Theremin Tutorial
More music for your ears! This soldering kit we designed to be wireless controlled by your hands! Wave your hands in front of it to create different notes. By linking an ultrasonic sensor to the Arduino Nano, we can detect the range of your hand and then translate that into notes on a scale.
First, you should refresh yourself on soldering safety!
WARNING: SOLDERING IRONS ARE HOT. SOLDERING IRONS ARE NOT TOYS. ALWAYS WEAR EYE PROTECTION WHILE USING A SOLDERING IRON.
Ultrasonic Sensor → These sensors emit a non-audible audio pulse, and then listen back for echos. By using the speed of sound, we can determine how far away objects are!
Count all of your parts and verify everything is in your kit.
Locate the 100 ohm resistor and install it at position R1. Install the 1k ohm resistors in R2, R3, R4, R5, R6.
Install the LEDs with the long leg going into the circle hole.
Install the headphone jack.
Install the 4 pin connector, paying attention to orientation!
Locate the two 15 pin male headers and install on to the Nano. Next locate the 15 pin female headers, and install these on to the PCB using the Nano as a soldering guide. Solder one pin to hold it, then heat the single pin back up to help position it to make sure it is straight.
Locate and install the speaker. This is another component that must be installed in the correct orientation. The (+) should match with the (+) marking on the PCB.
Plug the ultrasonic sensor into the 4 Pin Female header previously installed.
Plug in the USB cable, and have fun making music!.
