The I/O Accessories Kit contains six cable assemblies which allow you to experiment with the I/O interfaces of the Sequent Learning HAT for the Raspberry Pi (available separately).
The Node-RED tutorial includes descriptions of each interface, teaching you how to interact with it without writing a single line of code. Command line and Python drivers are also available for each assembly.
Each accessory comes pre-wired with a connector plug. Simply plug it into the corresponding port and run the software.
The switch can be used to demonstrate how to read the contact closure inputs.
The thermistor can be used to measure ambient temperature using the 0-10V input.
The photoresistor will let you measure light. You can use it to turn lights on at dark, to see when somebody enters a room, or for any application which needs light. It can be read also with the 0-10V input.
Used also with the 0-10V input, the potentiometer will let you simulate the analog output of a sensor which you can display in Node-RED.
The sensor requires two connectors, one with 2 pins going to the RS485 data port and one with 3 pins going into the 4-20mA input port for power. Use Node-RED to read ambient temperature and humidity.
Plug the micromotor into the MOTOR port and use Node-RED to control the speed and direction. Use it with a SERVO connected to the 6 pin header (SERVO not included) and build a small robot driven by Raspberry Pi.
