Hi, my name is Oscar. I built a wheelchair with a joystick. It was fun to build and program. First I built the joystick. It was kind of easy building it. Then I built the wheelchair. I got confused with some of the pieces but I did make it. I had somebody hold the joystick straight up and down to reset both of the angles to 0. Then I had to make a page to put two buttons one to start and the other one to stop. The programming was kind of hard because I had to guess in some of the numbers for the angles. Sometimes it went crazy because I wrote the wrong numbers for the angles. I had to move the joystick forward so it could go forward and I had to move it back so it could go in reverse. Some times I had to reset the joystick because it got out of adjustment.
Below is a picture and the programming.
