DanceDanceSense

A close up shot of an accelerometer and ESP8266 mounted on a small protoboard.

DanceDanceSense is an economical sensor that can be worn to track movement. Accelerometer readings are sent as OSC messages via WiFi. The sensor is fitted with a small infrared LED that can be tracked with external cameras.

Bill of Materials:

1 x NodeMCU ESP8266 amzn
1 x ADXL345 Accelerometer amzn
1 x 60mm * 80mm Protoboard amzn
1 x 3.7V LiPo Battery & charger amzn
1 x 1.4V Infrared LED amzn
2 x 4.7kΩ Resistors amzn
2 x 10Ω Resistors amzn

Consumables:

Construction:

Cut the protoboard down 80mm x 28mm.
Solder the header pins for the accelerometer at one end of the board.
Fit the NodeMCU at the other and connect the 3v3 and GND to the accelerometer
Solder 10Ω resistors and LED into place.
Solder SDA and SCL to D2 and D1.
Solder 4.7kΩ pullup resistors for SDA and SCL lines.
Make a battery connector out of 2 header pins and hookup wires.

Hi! Subconsciously you already know this, but let's make it obvious. Hopefully this article was helpful. You might also find yourself following a link to Amazon to learn more about parts or equipment. If you end up placing an order, I make a couple of dollarydoos. We aren't talking a rapper lifestyle of supercars and yachts, but it does help pay for the stuff you see here. So to everyone that supports this place - thank you.
