Line Follower Robot Without Arduino or Microcontroller

Here I explained a line follower robot without any microcontroller or Arduino. This is very simple project for beginners. Here you have need not to use any programming knowledge. so lets try it ....

Step 1: Collect the Material

1. Two IR sensor
2. Two Dc geared motor 100/150 RPM
3. one Chessis
4. Two wheels
5. One Caster wheel
6. One motor driver circuit (L293D)
7. 12 volt charable battery

Step 2: Connect the Circuit

Here two circuit are shown 1st is on breadboard and other is schematic. Now you can make a circuit using these material. You can make this circuit on universal PCB or on breadboard.
