Matrix E-blocks2 Switch Board BL0145

Description

The E-blocks2 switch board allows a bank of eight switch inputs to be added to the E-blocks2 system.

The E-blocks2 Switch x 8 is a useful tool allowing you to control what is happening in the system. The switches are push to make and active high, meaning the voltage to the microcontroller port pins is low when the switch is not pressed and high when the switch is pressed.

Each switch is in the active high configuration. When the switch is pressed R1 pulls the signal to the E-block port pin high. When the switch is not pressed R2 pulls the signal to the E-block port pin low to avoid picking up electrical noise from the environment (floating).
