The SmartSwitch can trigger HTTP requests with the click of a button
Inspired by the “360 Degree LED Indicator with WeMos D1 Mini ESP8266” I created a Notifications Button based on the Lolin S2 Mini featuring only one button, a WS2812B LED strip and a vibration motor.
The button can be programmed with Circuitpython. You can find the code on github.
My latest revision of the smartswitch supports the maximum (due to the MCP23017) of 16 button. I’ve used anti vandalism buttons in different colors so the user can identify the function easily.
All the other components are the same like in the last revision.
The photon is able to act as a native keyboard so I decided to build an input device for some computer games. The main parts are the big red and green push buttons which act as classic game buzzers. When pressing one of the big push buttons the WS2812B LED matrix lights green or red depending on button which was pressed first. Additionally the DFPlayer mini which is connected by UART to the photon is playing a buzzer sound on the small speaker.
The five additional buttons are used to trigger additional keys which are useful while playing games.
The pushbuttons used in my smartswitch did no longer respond correctly to presses so I replaced them with some better buttons and adjusted the case. Additionally I included a DFPlayer Mini to play some sounds by pressing a button.
While searching for the perfect button it stumbled across the “No!”-Button and was able to build a photon into it:
This button connects to a WS2812B lightstrip surrounding my bed which makes a nice indirect light source.
The speaker in the “No!-“Button is also connected to the photon so it can play a nice Super Mario theme when double pressing the button.
