โปรเจกต์ DIY - Digital Lock - ด้วย Processing

This easy and simple DIY digital lock doesn't need many components, and if you have the basic Arduino pack from a few years ago, you have everything you need. It uses Arduino and Processing codes. The LCD is used to know if the lock is opening, closing, etc. The motor simulates the locking mechanism, ant it is powered by a 4,5 volt battery and controlled via an H-bridge.

STEP 1: HARDWARE

You will need:

1. Some wires
2. One LCD 16x2 without I2C
3. One potentiometer of 10 K ohm
4. One DC motor type 130 from 1-5 volts
5. Two resistors of 220 ohm
6. One battery of 4,5 volts
7. H-bridge type L293DNE

STEP 2: LCD

Here are some images so you can see how the LCD is set up.

STEP 3: MOTOR

Here I leave you, again, some images so you can see how the DC motor and the rest of the components are set up - I'm not good at describing

STEP 4: SOFTWARE

If you don't have the Arduino IDE, you can download it from this link:

And if you don't have Processing either, you can download it from this link:

The Arduino and Processing code is below.
