A configurable IoT launchpad
Rename src/secrets.example.h to src/secrets.h
Fill in the values for your wifi and PubNub keys
Build and copy to your device
The below Node Red example can be ran to see your values come through
Change the PubNub keys in Node Red also.

For - DIY makers / software devs
Not For - Production NASA space shuttle dashboards that can withstand and communicate travelling and operating in the harsh conditions of space
I like automation. Sometimes I don't want to go to my web dashboards or forms, or open a phone, find the app, hit a button or create a record manually
This is a quick easy way to invoke things to happen or record events that don't need any input, like "Fed dog at 8 am" just by pressing a button. Or "start timer for 15 minutes"
- PubNub
- WiFi Network Connectivity
- Node Red
(This could be way cheaper)

- Fed dog
- Timers
- Pretty colors
- Easy to get started
- Not much infrastructure required using free cloud services
- Cost
- Only works with network & internet connectivity
- On/Off switch
- Animation let's you know everything is ready to go
- LED let's you know the device is powered on
- Play mode (push whatever buttons you want without publishing to the cloud)
- Fairly accurate estimation of battery expectancy
- Publish battery voltage (possible low battery warning)
- Really nice enclosure: https://www.adafruit.com/product/4339 or 3D print or make one from wood
This didn't work even though ESP32 was there using the PubSubClient https://www.pubnub.com/blog/pubsub-nodemcu-32s-esp32-mqtt-pubnub-arduino-sdk/
