After having completed my first Arduino project (which can be found here) I wanted to try and create something that had more of a practical use. My idea behind this project was a way of aiding the visually impaired.
By the end of this project you will have created some touch sensitive desk trays which use audio labels that are re-recordable.
Feel free to modify it and make it your own once you have completed these steps.
During this tutorial I have provided serveral links to Arduino's own tutorials and more about Arduino can be found here.
Hovering over the image squares gives you more information.
Total time to complete: 1.5 hours (you do not need to complete all of this in one sitting)
Please note that as always you will need a computer with USB capabilities to program your Arduino.
Step 1: Things you will need
Step 2: Touch sensitive pin with 1 LED
Step 3: Making touch sensitive with 3 LEDs
Step 4: Connecting up the trays
Step 5: Attaching the speaker
Step 6: Attaching the microphones
Step 7: Adding a recording button
Step 8: Finished product
