Have you ever felt like an idiot when you walked out that door and forgot to bring a face mask with you? Yea I totally feel you. Not only does that provokes animosity towards you, but it also has a potential risk for your health, especially during this global pandemic and that you're living in the US.
With the grudges I've held against my idiotic self, I decided to build something to reminds me to wear face mask whenever I want to go outside. And that's when an idea of a facemask-reminder-slash-atm strikes me, and here I am present it to y'all.
So this is a fairly simple project, probably one of the simplest one out there, that I think anyone with a bit interest in hardware and happens to have an Arduino, as well as some other components and bit of cardboard, can build with ease.
- 4x4 Keypad
- A Motion sensor
- a 16x2 LCD
- an Arduino Uno
- a small breadboard
- Jumper wires
- Piezo Buzzer
The idea here is that whenever you pass through it, it'll buzz so loud that it's irritating and makes you just want to smash it! (Don't) You just have to pick up a face mask to stop its annoying noise. The LCD and the Keypad is just for inputting and keeping track of the number of face masks there are. That being said, the optimal place to put this thing is near the door.Wiring
Just follow the image below:
It is as easy to use as it sounds! You walk pass it, it buzzes, you grab the face mask and go away while the amount of face mask displayed on the LCD decreases by one.
When you first plug it in the power supply, the first thing to do is to input how many face mask you're planning to put in. To input, you simply hit the number buttons and hit D to enter. If you make any mistakes, just press A during the process to backspace.
If you input the amount of more than 100, it'll returns error and you have to redo it by hitting any key on the keypad.
When the first step is done (say 10 face masks), now the LCD is like this:
When you run out of face mask, the following will appear on your LCD:
As it stated above, you just need to press a random key button to start the inserting process again.
Pretty simple, eh?Pictures of how I made the whole thing
