Building Wearables Session at CampJS

Programming ESP8266 with EspruinoJS

Getting set up

The boards are flashed with Espruino. Install the CP2102 driver and Espruino IDE from the Chrome extensions store. See Anna's blog for more details.

Use the GPIO pin numbers in the code e.g. pin 4 not D2.

Making an LED flower

Here's how to add an RGB LED to a silk flower

Use heat shrink tubing to insulate the leads on the LED. Use different colors of heatshrink so that you can identify the common lead later. image

Remove the green plastic core from a silk flower by pushing it out from the back image
