Last Christmas, Katie designed an LED Christmas tree bauble decoration for element14 presents. So, she decided, why not add a friendly snowman to it this year, using some of the same electronics concepts? Her IoT-connected snowman light is powered by the Raspberry Pi Pico W and uses the same MQTT system as her Christmas bauble.
