Keeping Hands Clean

Handwashing is one of the best ways to protect yourself and your family from getting sick. Learn when and how you should wash your hands to stay healthy. Wash Your Hands Often to Stay Healthy You can help yourself and your loved ones stay healthy by washing your hands often, especially during these key times when you are likely to get and spread germs.

This devise can help the kids or even you wash your hands regularly .


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

Step 1: PRINT the Parts

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 .

Step 2: GLUE the Parts

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.

Step 3: GET Your Parts

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.

Step 4: WIRE the System

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.

Step 5: Send the Code

plug the usb and send the code

Step 6: ENJOY

Now enjoy . easy right? told you.
