Introduction: Robot Car Tracking Line [ Easy Way ]
This instructable gives instructions for constructing a robot car that will tracking dark line ( black )
robot Car contain ( IR sensors) and when sensors on black line , (sender IR) send infrared but not received it on(emitter IR) here both of wheels continue running forward , but when car go out the black line, sensor send and received (IR) here the left wheel opposite his direction to backward , and car carved.

Step 1: Equipments
2.Relay 5-6 V
4. 4.5 Volt battery to motors and 6.0Volt to circuit
7. (IR) emitter, receiver
9. Resistances (R1=6.2 M Ω, R2= 82 Ω, R3=10KΩ )
Step 2: Construction
connect the circuit as shown in figure
also sometime you need to add black tube in IR receiver ( more accurate in response )
Step 3: Done
also you can be more creative by replace IR with microphone for example or anything
