The $5 Automatic Alcohol Dispenser

So with quarantine being lifted off my country I noticed alcohol dispensers in an attempt to stop the spread of the virus but these alcohol dispensers required to be touched making it a possible route for being infected with the virus. I made this automatic alcohol dispenser to stop that possibility. This low cost 5$ dispenser is beginner friendly to make by not requiring any programming skills and arduino.

Step 2: Parts and Materials

Here are the parts were gonna need

Dc pump x 1

PVC tube x 1

Adjustable Spray Nozzle x 1

TIP32C Transistor x 1

IR Proximity sensor module x 1

Micro USB breakout board x 1

1N4002-4007 Rectifier Diode x 1

100R 1/4W Resistor x 1

Mini Breadboard x 1

Prototyping board x 1

Project enclosure (like a mason jar)

Step 3: Prepare the Enclosure

I reused an old coffee container for our project

Step 4: Cutting the Prototype Board

Our prototyping board is too large for our project to save some for future projects lets cut it down to a smaller size

Step 5: The Cap

Get the cap of your enclosure and make holes for the pvc tube and motor wires to go. You can secure them with hot glue.

Step 6: The Circuit

Follow the diagram above for the wiring of our parts.

Step 7: Wire It All Up

Once you finished wiring up the circuit it should look like this.

Step 8: (OPTIONAL) 3d Print an Enclosure

To make the project look better I 3d printed an enclosure for the electronics. This step is completely optional this is just for aesthetics

Step 9: Finished

Congratulations you just made your very own low cost alcohol dispenser!

To use it just plug the micro-usb cable at the back and put your hand in front of the sensor.
