hey , i am new to Arduino and and not to sure what i am doing. Basically for a university project i want to create a mirror which shouts compliments when people walk past. im guessing i will need a proximity sensor to detect the people walking past ? as well as a small speaker for the wav/mp3 to be played through. ? As this will be displayed in the town centre i need it to not be connected to a computer and all be saved to the arduino.
Can anyone help me on what i need to get and if i need to buy things specific for arduino or if everything is compatible ? any help will be greatly appreciated
