How To Make A DIY Arduino Line Follower Car At Home

[@ngopidirumah1510]

For those who seems doing the tutorial correctly but the robot keep moving straight, do this step: ADJUST YOUR IR SENSOR POTENTIOMETER TO LOW, keep it adjusted between reading surface and stop when crossing black line, @diy builder didn't explain it, but this is very important step

Step 2: Hardware Installation Hardware Installation Hardware Installation 1. Assemble the 2WD Smart Car Chasis 2 Wheels 2. Connect the IR sensor to Analog to Digital and Comparator Module IN1 > IR Sensor 1 IN2 > IR Sensor 2 IN3 > IR Sensor 3 IN4 > IR Sensor 4 3. Then, connect the output pin to Arduino UNO analog pin OUT1 > A2 OUT2 > A3 OUT3 > A4 OUT4 > A5 4. Connect Vin to 5V and GND to GND in Arduino UNO 5. Then, connect the motor driver pin to Arduino UNO pin IN1 > D10 IN2 > D9 IN3 > D6 IN4 > D5 6. Connect the both motor to motor driver Motor A > Right motor Motor B > Left motor After completing the connection, connect the Arduino to power supply with USB cable.

Good video and also good coding. Thank you very much for your wonderful work. Still i have a question. Do i also need to supply the arduino with a 5v battery or only the motor driver? The dc motors run faster if i supply the arduino with a seperate supply but i do not know if this is safe or does it damage the arduino module.

[@guillaume8437]

First of all, wiring is essential! You may need to adapt either the code or the pinout. Beware also of the sensors output! If the voltage difference of level is too low, you may not recognize the line. Another point is that I don't understand why in the code we have ANALOGREAD : if(digitalRead(left)==0 && digitalRead(right)==0){ else if(digitalRead(left)==0 && !ANALOGREAD(right)==0){ else if(!digitalRead(left)==0 && digitalRead(right)==0){ else if(!digitalRead(left)==0 && !digitalRead(right)==0){ I have not tried it but it doesn't look normal.

[@dipayandutta9929]

The same problem occurred! Even I changed that one '!analogread(right)' into '!digitalread(right)', Then also It was going straight and didn't follow the line. Also, I modified the path from narrow to broad, and the same things happened, It was going straight. The speed is also very high.

Hi DIY Builder, i also tried building the same, however, L239 motor driver is not passing any commands to rotate motor (wheels are not rotating) using 9V batteries x 2. Wanted to know, if is power issue. Tried writing a new program just to rotate wheels, still nothing worked.
