A simple line follower robot using Arduino UNO rev3 board
- The whole project is built using the following -
- Arduino Uno rev3 board
- An arduino motor sheild which is used to control 2 DC geared motors (12V, 300rpm,300mA)
- 3 IR sensor module connected to analog pins(they can be also used to get digital input
- Arduino board and motor sheild are powered seperately from different sources
- Arduino board gets a input from a 9V batter from either the DC input jack(better option because of protection diode) or the Vin pin
- Don't forget to remove the jumper when using seperate power supplies
- Motor sheild is powered by a battery of 1.5V cells (12V total) using the EXT_PWR pins on the sheild.
- The chassis is made using acrylic plexiglass sheets with two decks for the boards and battery seperately
