This ESP32 Bluetooth Web page Turner Can’t Get Any More straightforward


Industrial Bluetooth pedals, designed to permit musicians to turn pages of sheet song on a pill, have any such inflated price ticket you’d be expecting for a distinct segment digital instrument. Reasonably than forking up to $100 USD over for the privilege of hands-free web page flipping, (*2*)[Joonas Pihlajamaa] determined to construct his personal extraordinarily low value model the use of an ESP32 and an affordable foot pedal transfer.

On the subject of {hardware}, it does’t get a lot more straightforward than this. All [Joonas] needed to do was once hook the pedal as much as one of the ESP32’s virtual pins, and plug the microcontroller right into a USB energy financial institution. From there, it become a device venture. With the ESP32-BLE-Keyboard library, it simplest took a couple of strains of code to ship RIGHT_ARROW or LEFT_ARROW relying on whether or not the pedal was once temporarily tapped or held down for somewhat; permitting him to navigate backward and forward throughout the pages with simply one button.

[Joonas] mentions that the ESP32 building board he’s the use of is simply too massive to suit within the pedal itself, although we wonder whether the naked module may just get slipped in there somewhere. After all you’ll want to all the time construct your personal pedal with somewhat of additional room to suit the electronics, however for not up to $2 USD on AliExpress, it’s onerous to head flawed with this turn-key unit.

Searching for an alternative way? We lined a Bluetooth web page turner remaining month that doubled the inputs and packed all of it right into a good-looking wood enclosure.
