Our team is developing a product that will help people who are visually impaired. Our lights will light up when the RFID tag reader reads a certain tag number, one tag is left and one tag is right. When the lights turn on, they're bright and can be easily seen, meaning that it will be easier for a partially blind person to see the lights.

List of things we needed

1. 1x Arduino circuit board (bottom middle)

1. 1x RFID tag reader (top left)
2. 2x RFID tags (one card, one tag)

Step one is plugging each wire into its corresponding placement. make sure you plug each wire correctly or else this won't work, you can look at the right placement online. Also, plug in your Arduino board to a computer that can support the battery.

Attached below is the code used for this project. What it does is it reads the tag number that's pre-assigned to a card, and when that tag number is read by the RFID reader, then certain LEDs light up. This code programs the RFID reader to read a certain tag number, and then turn on certain LEDs depending on the tag number.

We need to make the casing for our product. It needs to hold the small circular motherboard that houses the lights, it needs to encase the larger Arduino board, and hide the wires. The screenshot above shows what we designed to do those tasks

Now after you have plugged everything in, coded all of it, and put everything in their 3-D printed case, you can now try it out. When the lights turn on depending on what card, then it works.
