A friend sent me the link for this fun musical necklace by Ezgi Ucar. Get ready moms, your kids are going to be asking for this one! You can create beats or music sample sounds wherever you are. The “beads” can be interchanged, so you can have fun playing with different looks and sounds. Let’s get right down to the cool construction.
Check out the way she uses the male headers mounted on top, so they can be plugged into the female headers on the necklace. It’s a clean way to add versatility to a project, which is awesome. Ezgi talks about how she handled the hookup to the pin.
I decided to use one analog pin to get the signals from the buttons. I put 2K resistors in between the female headers on the necklace, and in between each button on a pendant. This allowed me to differentiate the signals coming from different buttons by their potential differences, using a single analog pin.
Hardware includes an Arduino Uno and a Wave Shield. A shield allows you to load the sounds onto an SD card, so they are available for the program’s use. A small computer speaker was also used, as a typical piezo is too faint. Hey, if you are going to make music, you need to be heard!
Make sure you check out Ezgi’s link above for more information about her creation. Then, make something musical yourself like our new FLORA Midi Drum Glove. You’ll be tapping out a beat in no time!
