How to make a DIY Obstacle Avoiding Robot Car using arduino without servo

Hello All, In this tutorial we are going to explain how to make a DIY Obstacle Avoiding Robot Car using arduino uno r3, L293d motor driver shield.
Note: We are not using servo in this build.

I was able to run this with a couple of modifications - I powered Arduino with 5V and in the circuit connection attached VCC pin from ultrasonic to 5V and its Gnd (instead of 9V as you have described). It worked fine. The software required no modifications but you need AFMotor libraries.

True

Can u use a 9v battery to power the arduino?

[@dinithinith9223]

Thank you so much

In opening of codes file
"The file is formet not supported"
this line is show

[@dinithinith9223]

Today l made this robot

[@kalashdesai1104]

can u share the AF motor library

[@punitugoyal434]

Can I attach driver module to 9v battery instead of powering Arduino

[@QuadStoreRobotics]

Yes you can

[@sadabraza4841]

With sarvo?

[@SAISAREN]

Bro when I verify it is showing error what to do

[@tek-b5098]

please
upload the links

[@mahmoudrashwan6077]

cant find the code ?!

[@warriorpenguin3722]

i have done as you have done in video . but when the obstacle come the robot crashes into it and sometimes motor torque is very low that the robot doesn't move what to do now ??

[@QuadStoreRobotics]

First make sure if your ultrasonic sensor is working. In serial monitor see if you are getting values of ultrasonic sensor. You can always increase the motor speed in the code. Also check if you are using good batteries.

i will check that my ultrasonic sensor is working in serial monitor
