TinyDuino / TinyZero with NeoPixels
« on: June 14, 2019, 01:27:23 PM »
I am using a TinyZero with the Tiny WiFi Shield to create a web host on my local network. This lets one use any browser to query and control the TinyZero. For example, turn on a LED or a NeoPixel (a WS2812B). This works well when the TinyZero is connected to USB for power, but not when it's solely on fully-charged battery power (150mAh lithium-ion)  The LED will still turn on with battery power, but the NeoPixel will not turn on.

USB Power: LED and NeoPixel
Battery power: LED only

Why is this happening?
And how can I illuminate one or more NeoPixels without requiring a connection to USB power?

I want to try out Pushsafer www.pushsafer.com using my Tiny WiFi Shield, but their SendEvent example uses the ESP8266WiFi.h library.

Has anyone adapted a sketch that uses the ESP8266WiFi.h library to use the WiFi101.h library instead?

TinyDuino / TinyZero with LED

When I connect an LED to an Arduino digital pin, I usually put a 220-ohm resistor in series. However, since the TinyZero is 3.3v instead of 5v, is that still necessary?
