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

Arduino Bluetooth Crafts

(and partner-in-crime, Abbie). Now, I’m off to the next stage of my life, so I decided to build this friendship photoset for Kevin and Briton to remember our golden era. We called ourselves: “The Suite Bros”.

This project is actually an extension of the “Voice Activated Arduino (Bluetooth + Android) by ASCAS. I highly advise you guys to read his project first! ASCAS really simplified the fundamentals of the project down super well.

It’s been a little more than a year since the last time (and the first time) I took Electronics at Pomona College and learned to use the Arduino. I thought ASCAS’s project was fun and easy-to-learn. He has great project. Check him out when you can!


It’s a DIY photoset that has LEDs inserted in the frame and in the back of photos that are activated by your voice commands via an Android’s speech recognition app. The app is called “Android Meets Robots: Voice” by SimpleLabsIN. This app converts your voice commands to data strings and sends them to your Arduino via Bluetooth. You can build the photoset in any way you want. I just want to show you how I built mine in this Instructable.

Step 1: Materials and 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

Read through this Instructable to make sure you understand the basics of this project:

“Voice Activated Arduino (Bluetooth + Android)” by ASCAS

Step 3: Prepare your photos and LED containers

  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.

Step 4: Assemble the Bluetooth

This step is referenced directly from ASCAS’s instructions. I believe he made very clear instructions and a great diagram. I put this here for your convenience. Remember to connect to 3.3 V and not 5 V (like the diagram).

“Grab some jumper cables and power the Bluetooth module with 3.3 volts. Remember, the bare HC-05 run on 3.3v and not on 5v. Now connect the RX (pin #0) of the Arduino to the TX pin of the Bluetooth module and the TX (pin #1) of the Arduino to the RX pin of the Bluetooth module. (refer to the image above)

Step 5: Assemble the LEDs

The schematic seems quite complicated, but it’s not that bad. In my diagram, I connected LEDs to basically all the pins left.

  • Connect LED 1 To Pin #2
  • Connect LED 2 To Pin #3
  • Connect LED 3 To Pin #4
  • Connect LED 4 To Pin #5
  • Connect LED 5 To Pin #6
  • Connect LED 6 To Pin #7
  • Connect LED 7 To Pin #8
  • Connect LED 8 To Pin #9
  • Connect LED 9 To Pin #10
  • Connect LED 10 To Pin #11
  • Connect LED 11 To Pin #12
  • Connect LED 12 To Pin #13

I forgot to purchase blank circuit boards, so my actual setup looks like a complete mess. I basically soldered the ends of jumper cables to ends of LEDs. Lesson learned. But hey, it works!

So yes, I suggest you to use blank circuit boards to connect all of the GND components of the LEDs

Step 6: Programming your Arduino

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.
