Arduino RC Car For The Snow - Design and Build

3. Final Car (built when I was in the 8th grade, pre-covid)

---------------------------

Ok, a great way to start the first blog. This is probably one of my favorite Arduino inventions that I made with my friend, Blake, where we made it for a snow-themed online contest.

Supplies:

-2 Gear Motors

-1 Arduino UNO

-1 12 Volt battery

-1 HC - 05 Bluetooth module

- A ton of jumper wires

- An Arduino motor driver

---------------------------

Step 1: Schematics and set up

Design (3D file and Sketch):

Schematics and steps:

Here's the schematic, so, do the following:

- Connect Arduino UNO to the motor driver

- Connect the two gear motors to the motor driver as shown below

- Connect the battery to either Arduino ( what I did ) or to the motor driver, as shown in the schematics, I personally recommend a 12-volt battery.

- Connect HC 05 Bluetooth module and put Rx to Tx and Tx to Rx

Step 2: 3D print the Ski

Remember to keep the weight as low as possible, so the RC car will be able to move well and stabilized in the rough snow terrain, always remember to keep the Arduino and wires safe and make sure the wheels are good enough for going off-road. I used a 12-volt battery to make sure my wheels would have enough power to ride in the snow and in off-road rough terrain. Adding a headlight is optional, and is just a nice feature to have. Also, (very important side note) keep the fill percentage in the ski as low as you can, so it isn't too heavy. One of the creators of this, Blake, kept the fill at about 49%, so make sure it's not too heavy.

Conclusion:

Hope you had fun building it! The app name is " Arduino Bluetooth Control " and it works just like a charm! Have fun! Also, try not to throw snowballs at it (it'll break, I know from experience)
