Hand-Gesture Controlled Car

The Hand-Gesture Controlled Car utilizes flex sensors on a glove to control several actions on an RC car, consisting of driving it forward and backward and opening/closing a servo-controlled gripper. The flex sensor senses the fingers bending, and when it senses certain actions, it controls the car.

Final Milestone

Third Milestone

My second milestone consisted of me connecting the flex sensors and the four motors onto one Arduino.

 

Second Milestone

For my second milestone, I expanded on my first milestone by adding two servo motors and two DC motors, with one flex sensor controlling one motor, respectively. This milestone was the most complicated thing I have tried to do so far, because I had to learn how to use a L298N Motor Driver. I found a diagram online, which I used as a reference point to connect my two motors, and I also used the diagram to figure out how to connect the motor driver to the arduino itself.

FIRST MILESTONE

For my first milestone, I introduced flex sensors into my project by writing a simple program that would output the value for each into the serial monitor on my computer as I bent each sensor. I first had to figure out how to use and code flex sensors and then create a circuit that would work with the sensors properly. This was a fairly simple milestone that utilized flex sensors, 22K ohm resistors, and simple code to read the bend of a flex sensor, a tool that will be utilized a lot more in the second and third milestones of my project.

STARTER PROJECT

My starter project, the TV-B-Gone Kit, works by using four infrared LEDs that use the same frequency that TV remotes use. The LEDs send out the “off” frequency for every type of TV in the US and when the frequency reaches the TV, the TV is tricked into thinking that the remote is telling it to turn off and ultimately the TV turns off.
