Project Suite Bros: Voice Activated LED Friendship Photoset (Arduino, Bluetooth, Crafts)

MATERIALS

• HC-05 Serial Bluetooth Module
• Assorted LEDs – I used about 12 LEDs
• Jumper Cables
• Arduino UNO
• Power Supply for Arduino Electronics Wall Plug
• USB for Arduino
• Drip Mat – Just a plastic cover I used to write “Always a party when we’re together”. For crafts purposes.
• Construction Paper – Not much needed
• Plastic Microwave Tray – Used this as the photoset frame. It was $1.50 at the DAISO store
• Baby pack lunchboxes – Used to place underneath photos and to contain LEDs. $1.50 at DAISO

EQUIPMENT

• Solderless Breadboard (for testing)
• Soldering Tool Kit – Buy a decent one for yourself!
• Basic Power Drill – Only need it to drill a hole through the photoset frame

Step 2: Understand the Basics

1. Print out your photos and make sure they fit the LED containers (aka. baby pack lunchboxes).
2. Use the LED containers to draw a circle on your photos.
3. Cut construction paper (pick any color you like) so that it wraps around the LED containers on the sides. Then, attach your photo on the bottom of the LED container with tape or glue.
4. Find out where you want to place your photos + LED container units on your frame board.
   • (Optional) I laminated the photos, so they’d look more cool.
5. Drill holes where you wish for your LEDs to show up.
   • I drilled about 12 holes – two for each photo, two in the center, one on each side, and two on the bottom.
6. Add any creative text or decorations on the photos.
   • I cut out the words “THE SUITE BROS” and placed each word on each photo. Then, I taped on yellow dividers.

This next part is also very important. Once again, ASCAS has given an outstanding explanation. I’ve pasted it here below (but please check his page):

Understanding The App

Before you program the arduino, you must first learn how the app works. The app work by recognizing your voice command, it will then display the words that you’ve spoken then sending data/ strings to the arduino via bluetooth. What’s a string? A string is like a word, you can make conditional statements out of it [ex: if (voice == “*computer on”) {// turn Pin #2 on} ]. The “voice” is your string, “==” is your condition (means equal to), “*computer on” is your command and the code inside the curly-braces “{ }” are the codes to be executed once your string matches the command condition.

What’s the format of the string? How does it know when the next command kicks in? How does it differentiate a set of words from a new command? The app sends strings in this format *command#, the asterisk (*) indicates the start of a new command and the hash-tag (#) indicates the end of a command. I was able to remove the hash-tag (#) after each word in the conditional statement was not able to remove the asterisk (*). You’ll need to start your command condition with an asterisk otherwise the sketch will not work.

How Can I Change The Commands?

You can see that the “*TV on” is highlighted from the image above. If you want to change the command to ,humm let’s say “open garage door”, you can replace the “*TV on” with “*open garage door”. Always remember to start the command with an asterisk.
