- Tue Oct 31, 2017 10:05 am #71418 Hello! I wanted to connected my wifi module to an Arduino uno. I only have little knowledge behind these embedded things, but would happily learn about them. As I've searched I've seen that there are different types of these wifi modules. My first question is that is there a difference in the way of connecting it to an Arduino? My second question is that how do I connect my Wifi Module to my Arduino Uno? The pictures are shown below. Third is that my plan is that I would send data to the Arduino uno probably like a number code using the wifi module. Then this number code would be then use on a Keypad to open a Solenoid Valve. Would anyone help me connecting the wifi module, keypad and the valve to the Arduino?

It's better to start learning the ESP8266 by getting yourself a stand alone ESP development board first (they cost less than €5/$5, see my signature below).
After you're comfortable with the ESP, you can always experiment with other setups.

So you'll only need a ESP8266 board, a keypad and a relay (for the solenoid): I think the best bet to start off with is a Wemos D1 board and a Wemos relay shield.

For a keypad, you can use the pad as in your picture, but you can also attach a TFT-display with touch screen and make it all a bit more fancy (I'm working on a touch screen door entry system at the moment).

Assumption is the mother of all f*ckups. At least: that's what I'm assuming.

So Arduino is out of the picture for this idea
