- Arduino Uno connected to 10kΩ Potentiometer and NRF24L01+ radio module.
- Arduino Uno connected to ADXL345: 3-axis Digital Gravity Sensor Acceleration Module Tilt Sensor and NRF24L01+ radio module.
When potentiometer resistance value breaks a threshold, data is sent from the accelerometer node & displayed.
Data from each sensor is put through a software filter to remove noise.
