Circuit Documentation
Summary of the Circuit
This circuit integrates an ESP32 microcontroller with an ADXXL335 accelerometer and is powered by a pair of 18650 Li-ion batteries. The ESP32 reads the X and Y-axis outputs from the ADXXL335 accelerometer and is powered through its VIN pin by the batteries. The ground connections are shared across the components to complete the circuit.
