After having fun on Arduino UNO, now I'm ready for making some small IoT projects.
I don't need so many ports, probably just one for input and one for output. And a cheaper price.
I was looking for the Pro model (or a compatible one), is it the right choice? But how can i program it, without USB connector?
Thanks,
By "Pro" do you mean Pro Mini?
The most popular option for IoT now is the ESP8266. The WeMos D1 Mini is reasonably priced and has a USB jack for easy programming. You will find it's more difficult to work with than the Uno but with enough persistence you can accomplish your goals.
I tend to prefer using an AVR based board (like Uno, Mega, etc.) with the W5100 or W5500 Ethernet module/shield for my "IoT" projects but I'm just old school like that. It's certainly more expensive, you can buy four or five D1 minis for the price of a Mega clone and a W5100 module.
I don't need ethernet... and just one input and 1 output.
Is it right an arduino pro mini or a clone? I've even found it for less than 3 €. As it will not drive a nuclear plant, could it be the right choice?
Finally, can I trust in video tutorials about "programming pro with arduino UNO", without using a FTDI usb to serial adapter?
Regards,
Do you take a look on Atmel ATtiny85, a chip and small AVR, you can upload arduino sketch with your UNO. Can work from 3V to 5V
I use one for a Cat automatic fontain.
Add this file to your IDE so you compile code for the Attiny85

It's not easy to find in Italy that chip... any other suggestion?
...and what about the programming? If I use the "nude look" arduino pro mini, can I program it easily with an arduino UNO? Or should be better to buy an FTDI adaptor?
Thanks,
Yes, UNO with blocked or removed chip can be used same way as FTDI adaptor via serial port, even more UNO in Arduino as ISP mode can program any AVR via ISP port.

Strongly recommend getting a standalone serial adapter. Using an arduino as a serial adapter is just making life hard on yourself in order to save a piddling amount of money. I use these guys (based on the CH340G, which is a fraction of the cost of the FTDI ones - I don't touch FTDI boards because I can't be sure whether they have counterfeit chips on them before I buy): http://www.ebay.com/itm/191196018631 (also sold at similar pricepoint by other vendors - the good ones are the black ones with the voltage switch on them; these have all the pins you need broken out and in the right order)
