I built a arduino based car. At first i wanted it to be rc but i accedantally broke the ir reccevier and i switched to a ultra sonic sensor so if it detects a object in front of it, it will try to avoid it.I used for this project things you can find in your home(instead of the arduino,ULN2003 and HC-SR04) beacus i wanted to show that you can do hardware projects without spending a lot of money and that you just need to look around you.
Im back and this time i dissasembled the car because im going to use 2 dc 6v motors so it can actually move now. I also soldered some wires to a dc motor module so i can connect it easier to the arduino and motors. I want to warn anybody that wants to dissasemble a water proof care that it would be so hard and messy because all of the components are covered in silicone(i think) and glue as you can see in the photo.
i had to scrap the rc car idea beacus i dont know how but the ir receptor dosent work but i switched to the first idea that i had and i used a sensor and now when it sees a object in a range of 20cm it will try to go around( i chose 20cm beacus it turns right or left really hard). I mounted everything on the “case” of the car but i left the arduino out beacus i still dont have a way to power it.
i made a wheel for the mototrs. It isnt the best design but i think it will work for a demo
i mounted everything on the “case” and now i just need to find a way to power the arduino nano beacus the battery that i have only has 3.7v and it isnt enough to power the module and the arduino nano
i made a case for the car but as you can see i am not that good at 3d modeling but it will do the job
i tested it with more motor,made a battery holder so it can have more power and added a remote but i tested it with only one motor
tested the reused motors and combined them with a arduino nano and a stepper model module
