After testing the code, and connecting it to the Arduino, the time for user testing dawned and arrived, but for all this it should be noted that I placed one of the servomotors above the compartment where the car is stored, so that it would give it a boost exit to the car, then I put the other servomotor next to it, on one of the columns that faces the ramp, to hold the blocking bar, and that this other servomotor was in charge of opening and closing this barrier, and the countdown that I placed it in front of the ramp, as it is worth mentioning that as the first instance I placed a stop at the end of the ramp, so that it would be where the cart would hit. Another thing I realized was that the barrier was working the opposite of how it should work, because within the code it had the servomotor to rotate in the opposite direction.

The user testing phase began, and several saw the project and gave me feedback, which helped me specify and take into account many improvements to the project, such as the countdown that honestly was not of much use within the project, or the echo That it was just the ramp, I needed something else to make it more fun, because what I did receive and it was the purpose from the beginning were comments that it reminded them of their childhood toys, I also received ideas on how to improve the project, such as putting and opening holes in the black wall, so that in some way or another "levels" could be created and depending on where the cart fell it was determined if it won or lost, all these ideas and comments helped me realize many important things. It is also worth noting that for the user testing I used a hotwheels cart, since previously I was using a truck-shaped cart and it turned out that it was too heavy for the ramp and would get stuck, which did not happen with the other cart, so I stay with the hotwheels. It is also worth mentioning that it made me realize that I had to improve the appearance of the ramp, because due to the inclination the car sometimes got stuck.

After the user testing, the next day I had to improve the project, so first I started by removing the black stopper that I had made, to be able to expand the track, so first of all I started thinking that I wanted to remove one of the servomotors, well No, these do not have a 360 degree rotation, so I later decided to use a DC motor, since it does make a complete revolution, so I put together a rotating wheel in which now the purpose was to be for the person who will play, first align the wheel correctly so that the cart can reach its final destination, which was a box, if the person does not make the cart pass it is a fail, while if the person manages to make it pass, the player wins. It is also worth mentioning that I removed the countdown, and modified the code so that now one of the joysticks would manage the DC motor.

After putting everything together and having it completely, it was time to paint it and give the structure a design, since it was based entirely on cardboard and Teip, then I proceeded to give it color and decorate it, and with everything painted, I proceeded to put a better base on it. to the ramp where the car was going to pass, because I had a problem there that when I painted it, the paint made the wheels of the car get stuck, so I had to cover it with a flatter surface, with this, it worked . Just like I added a support below the ramp, so that it would have an adequate angle for the car to pass in the correct way.
