Object following robot [ AAR-04 ]

Projects General Guidance
1

Hello,

I'm very interested in learning arduino! I've just started this long journey, and I have to say I'm intrigued about all the possibilities. I've just programmed a distance counter with a Arduino Uno. I'm very proud of it!

Now I want to move on to my next project. I want to make a object following robot. I have recently bought a Arexx Arduino AAR-04 robot. What kind of sensors do I need for it to follow objects.

Will the HC-SR04, A ultrasonic sensor, do just fine, or do I need something else?

Regards,

TurboArduino!

The ultrasonic sensor will measure how long it takes to receive an echo from a pulse that it sends. It will NOT tell you what the echo bounced off of or where the object that caused the reflection is.

So, yes, you'll need more than just an ultrasonic sensor.

Thanks for the answer chap!
So I've gone ahead and bought meself 2 infrared sensors. Problem is that I don't know how to connect them...

I've got my ultrasone sensor connected to GND, VCC, D4 and D8. But where do I connect the two infrared sensors?

Wherever you like, as long as the pins you use are free.
