GY 291 Sensor ADXL345 Accelerometer is an ultra-low-power digital accelerometer that has an output data range that scales from 0

KY-040 Rotary Encoder Module 360 Degrees 650nm Laser Diode Module USB: Micro USB (for configurationKY 040 rotary encoder is a device that generates an electrical signal based on how much the rotary input device (knob) is rotated and the direction it is rotating in. It is a position sensor with a knob and can be used to control stepper or servo motors with precision.
