Control a Espruino board with a gamepad

Hello Kari @user80672,

To clarify, which Espruino board are you intending to use? ref #1 above

"I would like to make a robot with a Espruino board . . . "

Will you be using I2C to communicate with the Espruino board? Is this what you had in mind?

Make sure the Bluetooth adapter supports BLE if communicating with the Puck.

This article implies ver 4.1 is required for BLE: http://noahklugman.com/talks/ble_presentation.pdf

p.5 "But: not backward compatible with Bluetooth Classic (including Bluetooth 4.0 Classic)"

but, . . .

" then something like Puck.js could communicate directly with them over BLE. " #2 above

@Gordon Does the Puck support Bluetooth LE 4.0 ? (yes?) - BLE 4.1 ? (?)

Features section doesn't specify, but both references are used on the page
http://www.espruino.com/Puck.js

and to add to the confusion wikipedia indicates 'Bluetooth_4.1'
https://en.wikipedia.org/wiki/Bluetooth_Low_Energy
https://en.wikipedia.org/wiki/Bluetooth#Bluetooth_4.1

This helps in Bluetooth version clarification
