Sensor Accelerometer MMA 3201 is a sensor used to measure the acceleration of motion of the payload when the payload was launched until the payload is delivered to the home again, Sensor Accelerometer MMA 3201 has a resistance to the gravitational force of 20g on the axis X and axis Y. Sensor Output Accelerometer MMA 3201 is still in the form of analog data so that the need for an ADC to process the data. Data released by Sensor Accelerometer MMA 3201 is a linear form of X and Y axis, the second determines the acceleration motion data payload. Accelerator sensor with MMA 3201 Feature Sensor Accelerometer MMA 3201 Sensitivity in two separate axes: 40g X-axis and 40g Y-axis Integral Signal Conditioning Linear Output Ratiometric Performance 4th Order Bessel Filter Preserves Pulse Shape Integrity Calibrated Self-test Low Voltage Detect, Clock Monitor, and EPROM Parity Check status Transducer Hermetically Sealed at Wafer Level for Superior Reliability Robust Design, High Shocks Survivabilit...

Background knowledge          Basic understanding on how the Segway works is; when the IMU is tilting to a certain angle, the accelerometer give command to the stepper motor to tilt to the respective angle. The gyro sensor reacts by giving command to the motor to tilt the angle to the reference position.           The main and most complicated issues of self-balancing Scooter are the sensors. The sensors are very important as they give us the inclination of the bar regarding the base and the speed of its angle change. For this kind of scooter, we need an accelerometer and a gyroscope. The combination of these two devices provides us of very precise results because the error of one is cancelled by the other and vice-versa. In short, we could say that the gyroscope tells the short-time reading and the accelerometer the long-time reading. This is the latest circuit which has Stepper motor, Arduino Uno, motor driver L293N and IMU sensor in t...
