Turn Everyday Objects Into Sensors With the Touch Board
Add interactivity to everyday objects: use your houseplants, cutlery and more to trigger sounds on the Touch Board!
Use your Touch Board to give voice to the objects around you. Record a message about which vitamins to take, a reminder to water your plants or even link your favourite song to a metallic photo frame.
You will need:
1 x Touch Board
MicroSD card reader
Select your objects
To begin, select the objects you want to make interactive. You can use any objects that are either conductive or metallic.
For this project we’re using a metallic robot, a metal lid from our vitamin jar, and an aluminium rivet inserted into our plant pot.
Change the tracks on the SD card
Take the SD card out of the Touch Board, insert into the microSD card reader and put the reader into your computer/laptop. Open the SD card and you should see a couple of files, including TRACK000.mp3, TRACK001.mp3, etc. up to TRACK011.mp3. These are the files that are played when you touch the corresponding electrode, so when you touch electrode 0 on the Touch Board, it plays TRACK000.mp3 and when you touch electrode 11 on the Touch Board, it plays TRACK011.mp3.
You can change the tracks to any MP3 files that you can find. So this could be songs, sounds or a voice recording. Make sure use the same naming structure.
With your files uploaded to the SD card, eject the SD card and reinsert into the Touch Board. Give the sounds a test, by powering the Touch Board, adding audio and touching the electrodes!
If you want to find these instructions about how to change the MP3 files, have a look at this tutorial here.
Attach the crocodile clips
Once you’re happy with the sounds you’ve uploaded, turn the Touch Board off again. Connect one end of the crocodile clip to the electrode of the Touch Board and connect the other one to the corresponding object.
Interact with the objects
Touch the objects, to set off your audio reminders or melodies!
