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. Features * I/O Accessories Kit for the Sequent I/O Learning HAT * Includes: * ON-OFF-ON Switch * Thermistor * Photoresistor * Potentiometer * RS485 Temperature and Humidity Sensor * Micromotor Kit Contents ON-OFF-ON Switch The switch can be used to demonstrate how to read the contact closure inputs. Thermistor The thermistor can be used to measure ambient temperature using the 0-10V input. Photoresistor 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. Potentiometer 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. RS485 Temperature & Humidity Sensor 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. Micromotor 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. https://elecena.pl/product/23440219/accessories-kit-for-sequent-i-o-learning-hat-discontinued 2023-05-13 https://elecena.pl/product/23440219/accessories-kit-for-sequent-i-o-learning-hat-discontinued 2023-12-27 https://elecena.pl/product/23440219/accessories-kit-for-sequent-i-o-learning-hat-discontinued 2024-09-18 https://elecena.pl/product/23440219/accessories-kit-for-sequent-i-o-learning-hat-discontinued 2024-11-29 https://elecena.pl/product/23440219/accessories-kit-for-sequent-i-o-learning-hat-discontinued 2024-11-30 https://elecena.pl/product/23440219/accessories-kit-for-sequent-i-o-learning-hat-discontinued 2025-11-28 https://elecena.pl/product/23440219/accessories-kit-for-sequent-i-o-learning-hat-discontinued 2025-11-29 https://elecena.pl/product/23440219/accessories-kit-for-sequent-i-o-learning-hat-discontinued 2026-01-12
