Capacitive Touch - Not working on Battery Power

Post by WayneTito »

Hi Adafruit Team,
I am a newbee and just went to thru the Capacitive Touch with Conductive Fabric & Flora tutorial using two touch sensors. It went great! Until I tried to run it on the battery (3 AAA) supply. It operates perfectly when connected to the USB port to the PC, but when I disconnect it and connect the battery supply the green light on the flora lights up, but the sensors don't change the neopixel color...it remains off. When I hit the reset button on the flora, it goes thru the reset cycle but still does not operate. When I reconnect to the usb, it works fine again.

Can you please help me solve this problem?

Thanks!

First check to male sure that your batteries are fresh. Also, capacitive touch circuits are sensitive to grounding. When connected via USB, it is grounded via the computer. On batteries, it would not be grounded.
