Sharing my enthusiasm too!

Right, that makes sense.

If your project requires an ESP as well as Bluetooth, you might want to hold on the final design and migrate it to the expected-soon ESP32, which supports Wifi as well as BLE.

I'm wondering, why use an Arduino at all? Do you need more I/Os than what the ESP8266 12E has?

I'd stumbled across Neils book a few days back. Its absolutely amazing, isn't it? Quite an exhaustive resource.

It's a DIY project and the Arduino Mini Pro is easier for end users to handle. WiFi & Bluetooth are optional and function only as wireless to serial interfaces. It's actually two projects that can share most of the code - one needs all of the pins on the Arduino. And the Arduino Mini Pro has an onboard 5V LDO allowing more flexibility in providing power.

Finally, I'm 74 and in poor health so I dislike delays.
