CircuitPython Signals

Connecting various sensors, switches, and indicators is

easy with Crickit.

The Crickit with Circuit Playground Express is shown at

the left.

Note that external pull up (or pull down) resistors are

needed on the Crickit Signals block as Seesaw does not

have the capability to set internal pull up or pull down

resistors like on direct microcontrollers.

Connections to a Crickit with Feather board are

identical.

Note that if you plan to use CircuitPython, the Feather

board you choose should be one that is supported by

CircuitPython (there are a few Feathers that cannot be

programmed with CircuitPython).

The Signals block on the Crickit HAT for Raspberry Pi

gives you 8 bidirectional general purpose input/output

(GPIO) (analog/digital) ports.

Since the Crickit HAT takes pins away from the

Raspberry pi to control everything, the Signals block

helps to provide some pins back and they all can accept

analog input too (unlike RasPi pins).

You may want to add buttons, LEDs, switches or simple sensors to your robot project. With Crickit, you get 8 x 'general

purpose in/out' (GPIO) pins called signals. Each signal can be a digital input (button/switch), digital output (LED, for
