Hello, this is a remix of https://www.thingiverse.com/thing:109524 car chassis. I made some little change with idler whell joint. You can directly hot glue your idler whell below the chassis with perfect fit. And there is an Arduino Line Follower Robo Car recipe below for you, enjoy.
Hello, with this Project you can make your own Arduino Line Follower Robo Car. This Project need mediacore Arduino knowledge. The line follower car requirements as below:
1x Arduino Uno (https://goo.gl/VHwGMK)
1xL298N Motor Driver (https://goo.gl/24dyj6)
2x100 RPM Dc Motor with Wheels (https://goo.gl/WNRM2C)
2x Reflection Sensor (https://goo.gl/i9V4sQ )
1x idler Wheel
1x 7,4 Li-po Battery
And some time.
First print 3D Car Chassis. Hot glue DC motors and plug whells to 3D printed chassis below. Solder DC motor anot and catot with jumper cables. Connect them on the tiny breadboard. Connect li-po battery to L298N motor driver +12V and GND port. Plug a jumper cable to +5v and GND to L298N and connect them Arduino Uno’s (5V to Vin and GND to GND) pins. Hot glue idler whell to chassis. Hot Glue motor driver, Arduino and lipo on the chassis. Upload this code to Arduino. And its ready to go. You can put a switch between lipo and motor driver. Not you can test this Arduino Line Following Robo Car with a parkour. Make your own line parkour with some tape. Have fun.
