Setup

The following Fritzing sketches should be used as example :

Ensure that

• The voltage source is shared across the Move S Board and the Arduino
• The battery VCC is guarded by a diode
• All inputs use pull-up resistors
• The BT_LED light voltage input resistance is larger than it's pull up resistor (in our case it's twice as large)
• The speaker pins have minimal resistance (this is important as higher resistance reduces volume)

If the sketch has been replicated, all components are functional and the software has been installed, readings from the circuit board should be precise.
