Car Controlled By Hand Gestures

  WEEK3 (last update 27/02/2023, Yibing) Process checking test the direction-controlling part. (Arduino code done ) try to add the speed controlling by setting different regions of angle that ADXL335 obtained. fix some coding errors Issues occurred speed of the car kit should be linear to the angles ADXL335 sensed. Here we simplify it to a nonlinear model.  Additional tasks see if other components/systems could replace the Bluetooth HC-05, or keep trying to connect the Bluetooth.

 WEEK2 (last update 09/02/2023, Yibing) Process checking set up the car kit by following the instrumentation figure-1 test the receiver circuit figure-2 figure3 get Bluetooth and AT commands connected so 'gestures' can be sent to the receiver later. Issues occurred We found some problems when connecting Bluetooth HC-05 to AT command. Group members have tried all the bauds and the different devices but we still can not figure out which part failed Bluetooth.  Potential limitations of this project Range Limitations: Bluetooth has a limited range of about 10 meters, which may not be sufficient for some car control applications. If you need to control your car from a greater distance, you may need to use other wireless technologies such as Zigbee or Wi-Fi. Power Consumption: Bluetooth modules like the HC-05 consume a relatively high amount of power compared to other wireless technologies. This can be a challenge when designing a battery-powered car control system Interferenc...

week1 (last update: 03/02/2023, Yibing) The system takes the movements of the hand as input that would be sent to the accelerometer through an analog channel. It gets three values: acceleration in the x-axis, y-axis, and z-axis. Arduino calculates the difference between the present value and the calibrated value, and from the result, it decides the command that the hand is trying to signal. It, then, sends the signal through a Bluetooth module. There is another Bluetooth module residing in the car kit. It has been paired with the module in hand so no noise interferes with the connection. According to the command received (F for forward, L for left, R for right, S for stop), the Arduino controls the motors to move the car accordingly. Process checking hardware-task-0 transmission circuit build  figure-1 figure-2 software-task-0  Test if ADXL335 functions correctly in sensing the movements. video-1 programming output shows what data the Arduino will receive if we rotate the whol...

Two primary circuits with one connecting the engines of the car kit and another worn on hand so as to read the movements of the wrist are required i.e. 'receiver' and 'transmitter'.   transmitter  Arduino Nano, Bluetooth HC-05, ADXL335, Resistors  receiver  Arduino Uno, Bluetooth HC-05, L293N,   All the codes related are shown here in the link.  https://github.com/YBBBB-C/gesture-Control-Car
