This Arduino GIGA R1 WiFi undertaking turns a espresso maker right into a extra accessible equipment
Arduino Staff — March 4th, 2024
Whereas lots of the issues we work together with each day have turn into extra usable by individuals with disabilities, the kitchen stays as one necessary space of our lives that also lacks many accessibility options. Considered one of these commonplace home equipment is the espresso maker and its array of small buttons or perhaps a touchscreen that may be onerous to see/contact. Orlie on Instructables has developed a set of wi-fi buttons and an accompanying receiver that translate easy actions into a simple, end-to-end brewing expertise.
Every button began as a customized 3D-printed shell with compartments for a AA battery holder, massive arcade button, and the perfboard that additionally contained the ESP8266 microcontroller. On this system, the ESP8266 communicates with the Arduino GIGA R1 WiFi board by way of Wi-Fi and an MQTT message dealer working on a bunch PC. This permits every button to be assigned a singular message that dictates the specified process to be carried out.
On the espresso maker, the GIGA R1 WiFi was wired right into a pair of ULN2003 stepper motor driver modules that transfer a gantry throughout a set of linear rails and ultimately push the corresponding buttons as soon as the proper place has been reached. Finally, this enables for these with much less mobility and/or dexterity to pick what they need from wherever in the home — throughout Wi-Fi.
To see how this undertaking was inbuilt higher element, you possibly can learn Orlie’s write-up right here on Instructables.
