I HOPE YOU WILL ENJOY IT

PS : not that that i need not use battery because it will not last , dont use 9v batt , use a power bank or a wall adapter to make sure its always powered up and ready to use . you can still improve the system , make it smaller or reduce the power with an arduino power sleep mode.

what we need for this project are :

- 3D printed models

-6 jumper wires : 3short

+3 long or just 6 long ones

-usb cable

-arduino uno

-high torque servo motor

-ultra sonic sensor

1- print all the parts

i used PLA 35 % infill

, 1.5 wall thickness

, 0.5 nozzel , 100% cooling fan

, no support needed,

note that the gear hole is a bit small so you can heat the part with a lighter then force the servo motor in , dont drill it , we need that tight grip of this to work .

As i made the parts easy to glue , now i advise using first super glue then use hot glue of the sides that will give you the best out of the two , for more crazy gluewiness you ca use epoxy.

The parts are easy to use and can be found every where , and when you get board with this system at some point you can just reuse them in another project.

It's pretty easy to do , if you have no idea on how to just follow the schismatics and please double and triples check before you wire the arduino , any wrong wires and you may burn it.

plug the usb and send the code

Now enjoy . easy right? told you.
