10-11 years old.
My name is Jakub Marek and I am 10. My home country is Poland.
Malin Bridge Primary School
It is a three wheeled car. I got the idea from the book 'Arduino adventures. Escape from Gemini station' by James Floyd Kelly & Harold Timmis. It is built from a magicians chassis, an arduino, a solderless breadboard,h-bridge & a hex inverter. My dad, who works at plusnet, helped me with this page and the Arduino car's making and connecting to the arduino.
It will drive forward and back, left and right with a remote. Honk a horn, set of its alarm when someone comes near, hits or kicks it. It will light its lights when its dark and lead you to your room and turn them off when its light. It will help carry things if your arms are aching and you need help*.
|Chassis||To keep all the parts safe.|
|Wheels||To move the Arduino car along the terrain.|
|Motors||To turn the wheels forth or back,fast or slow.|
|Battery holders||To store the batterys in.|
|Caster wheel||Acts like a third wheel.|
|Screws and spacers||To keep everything together.|
|Arduino Uno||The brain of the Arduino car and a microcontroller (like a small computer.) To learn more about this amazing hardware , click here. Arduino|
|Solderless breadboard||To connect the parts together instead of soldering them.|
|Jumper wires||To connect parts which are far away.|
|H-bridge||It is an IC(integrated circuit).It can control up to 2 motors. Wow!|
|Hex inverter||It's another IC that controlls which way the wheel turns.If you give it 1 on 1 leg ,then it will change it to 0 on the 2nd leg|
|Battery||Gives power to the Arduino car.|
|IR(infrared) receiver||This receives infrared signals so I can decode it and the arduino tells the motors which way to turn.|
|Remote control||Controls the car by sending messages to the infraread reciver.|
First I screwd on the arduino to the top of the chassis. Next I attached the motors to the bottom of the chassis and then secured the caster wheel to it. I then slid the wheels onto the motors. After that I fastened the battery holders and soon after I stuck the solderless breadboard on the top of the chassis.
First we conected all the GND (ground) pins from the h-bridge and hex inverter to the GND pin on the arduino.
Next we connected the power (5V) from the arduino to the h-bridge (pin 16) and to the hex inverter (pin 14.)
Then we connected the motors. We connected motor 1's power wire to pin 3 on the h-bridge and connected its GND wire to pin 6 on the h-bridge.
Then we connected motor 2's power wire to pin 14 on the h-bridge and its GND wire to pin 11 on the h-bridge.
We used 2 battery holders because 1 will give power to motors and the other to the arduino. Each batery holder provides 6V. We attached one battery holders power wire to pin 8 on the h-bridge and the GND wire to the GND rail. The other holder we connected to the Arduino with a jack plug.
Time had come to attach some wires from the arduino to the h-bridge so the arduino car could turn left and right and could drive forward and back. To do that we attached digital pin 7 to pin 10 on the h-bridge(so it could spin the motor 2 left or right). Soon after we attached digital pin 6 to pin 9 on the h-brige(so it would spin it at a specific speed).
We did a simmilar thing with digital pins 5 and 4 (except we connected digital pin 5 to pin 1 on the h-bridge and digital pin 4 to pin 7 on the h-bridge) to control motor 1.
I am still working on it and I will add a horn that will honk, light some light when its dark, set off its alarm when its touched or come to close to an object and help carry things.
To code my Arduino car, I used Arduino IDE and we also used the IR reciver arduino library. IR reciver library. You can find my code at GitHub.
|This is my design and notes of what it could look like in the end.|

* It will help your granma also carry things.
