Introduction
The two tactile switches are connected to Arduino pins 38 and 39, both active high. This means that the pins are at +5V when the switch is pressed, and at 0V (Ground) otherwise.

Note that pins 38, 39 are pulled low, i.e. they will be at 0V (and not floating) when the switch is not pressed.
Programming in Arduino IDE
The test code for the tactile switch is given below:
Programming in PictoBlox
To get the state of the tactile switch, you can use Tactile Switch () pressed block. This block can be found under evive extension. The switch whose state you want to check can be chosen from the drop-down on this block. It is a Boolean block which returns “TRUE” if the switch is pressed and “False” if the switch is not pressed.
Example
- Rotating the sprite if the tactile switch 1 is pressed.
