Android Arduino and Local Wifi

Using Arduino Project Guidance
1

Hi Guys :slight_smile:

I am new to the forum :roll_eyes:, would really appreciate your some advice on my queries please.
I am making a simple project where I am trying to control 2 stepper motor through an android app.

for this purpose, I will be using an arduino board with arduino motor shield and an arduino wifi shield.

Now , to the problems.

  1. I would like my android phone to connect with the arduino through the Wifi shield using the local wifi network i.e my home wifi router. Is this possible through some P2P , hotspot method? or will I need to set up a server for this to work.

  2. I am thinking of using arduino motor shield to control my stepper motors, however the shield spec states it can only support 1xstepper only, now could anyone confirm if I can still stack 2 motor shields + wifi shield ( any limit to shield on arduino?) on arduino and also if the motor shield works for uni directional as well as bi directional steppers please?

Thanks in advance guys! :smiley:

If you have an existing network, there is no problem for the Arduino to connect to it, using a WiFi shield. Well, there are some, but mostly they affect reliability.

If not, the Arduino with WiFi shield can NOT create a network for the phone to connect to. The reverse might be possible. But, it's your phone.

Yes, you can stack shields, as long as the pins used do not conflict. Since you haven't said which specific shields, you need to check which pins they use.

In general, motor shields tend to hard-wire the pins they use, so stacking two of the same shield will not work.

hey Paul, sorry took my time to say thanks,so here it is XD .. thanks a lot for your response :slight_smile: I am sure I will be asking a few more in time to come , thanks again!
