I'm almost new with Arduino and i'ld like to do an interactive project with a web app on iPad, and the Arduino, without the computer interaction.
There is not to much on the web about this, and different ideas: by web server, by cable or by bluetooth.
What should be better do connect?
What may I use to develop this, now a part is on Processing, put into the html code, should it work?
I want to do 3 simple interactive exercise between Arduino and iPad, they are into an educational project on the iPad.
The first exercise may use 3 buttons, referred on Red, Green, Blue and when you touch one of this on the iPad it would appear a ball of the right color and make a sound (like 1 note).
With the second you will activate a motor on Arduino using a button on the iPad. Then it appear a white page where you can draw (I've already done this second part with Processing).
Reading different resistance value on the Arduino it will appear different images on the iPad.
So 1 & 3 are closed together, because the input is from Arduino to iPad.
The 2 is the opposite, the iPad must activate the Arduino.
Bluetooth would probably be the most practical unless you want to communicate with the Arduino at a long range. If this is the case you can use internet (Ethernet or WiFi).
