Using the EVK1010A:
This kit is for the evaluation and development of applications using the AT42QT1010-TSHR (QT1010) 1 Channel QTouch™ Integrated Circuit (IC). This simple battery powered EVK1010A is configured with one capacitive key behind a 1mm acrylic front panel, where a touch is shown by the LED when KEY is touched.

• Insert the CR2032 3V battery provided into the battery holder on the EVK1010A.
Ensure that the battery has the correct orientation or the EVK1010A will not work.
• Touch KEY and the LED will illuminate.
• Remove the touch from KEY and the LED will switch off.
• If KEY is touched for longer than ~60 seconds, LED will switch off.
This is because the Max On-Duration has been exceeded and the QT1010 has recalibrated.
