4. 8 Push buttons

Step 2:

Step 3: OUTER BODY

Take any plastic box or even a soapbox is enough

And make the drills as shown in image

Step 4: Wiring Diagram

Step 7:

<p>Can you send the exact instructions / code? The &quot;instructions&quot; are a bit unclear</p>
<p>Hi there, </p><p>The reason for making this project opensource was to encourage Assistive tech maker's to manufacture this device, but we didn't saw any adapters.</p><p>one of my known contact was ready to manufacture this as product, and i had to hand over source code and other files.</p><p>In future, when i release version 2, i will reupload the code.</p>
