/* FTDI to ESP-01 */
The most basic is the following.

Apart from the obvious GND, VCC, TX and RX the only extra pin that is used is the GPIO0.
It is pulled down to GND to enable firmware upload.
The drawback is that you can't start and debug the program. It is just an uploader!
The more advanced way will follow in the next few weeks ...
