The touch sensor response is slow or the operation is not smooth.
Make sure you know the exact location of the touch sensors. The touch sensors are located right below the second and third cell. Learn the location of the touch buttons in the Dot Watch tutorial.
*Please note that touch sensors do not work when pins are moving.
If you press the touch sensors continuously when the pins are moving, it may not work properly. Please wait a moment (about 1 second) before retouching the sensors.
