Arduino Bluetooth Car

This DIY Arduino BT Car is perfect for 3D printing, electronics, and hobby enthusiasts who love building projects from scratch. Based on TAFHIM BIN NASIR's original project found here: https://www.instructables.com/id/Smartphone-Controlled-RC-Car-Using-Arduino/, this version adds a custom-made PCB and a 3D printable design for the chassis. The Arduino code is available in the link above, but I made some changes to add LED lights, which you can easily modify to include a buzzer for a horn sound. A comprehensive PDF file lists all the necessary components, including four 3mm LEDs, two 18650 batteries, and a battery holder. To enhance the project, I added an on/off switch and two-sided copper for the PCB. The top and bottom layers of the PCB are available in PDF format, with the bottom layer mirrored to ensure proper scaling. If you need assistance with the files or prefer to use a CNC machine or have it professionally made, I can provide the Gerber files. When it comes to the motors, I initially secured them using strong double-sided tape before deciding to drill holes and attach them securely with screws.
