Hey, im pretty new to arduino, been messing around a bit an want to take it to the next level. I want to send a command from my android phone through wifi to tell the arduino to display a seven segment LED Screen. I basically want to make it say different things on command without a laptop.
Im getting a lot on xbee but its quite expensive and if this is my only option how many will i need is it just the one and a xbee shield?
Are there any cheaper alternatives out there and what components will i actually need to achieve this?
A the moment i have the LED module wired up an a battery pack attached to the arduino. Im working on getting it done through bluetooth at the moment. for my next project it needs to be a wifi module rather than bluetooth. Rather than the code i need components and advce on how to go about this
