Whereas most of the issues we work together with day-after-day have turn into extra usable by individuals with disabilities, the kitchen stays as one essential 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, giant arcade button, and the perfboard that additionally contained the ESP8266 microcontroller. On this system, the ESP8266 communicates with the Arduino GIGA R1 WiFi board through Wi-Fi and an MQTT message dealer operating 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 right place has been reached. In the end, this enables for these with much less mobility and/or dexterity to pick what they need from anyplace in the home — throughout Wi-Fi.
