Phones are a problem in class, both because they're distracting and because some kids don't have them - and if the class found out they would die. Computers are slow to log on, taking 5-10 minutes of precious time per student to get them all ready. I realize that there are way more software hurdles, but cost is a primary concern, which is why I'm starting with parts. If I were to build a wireless remote that hooked up to a hub of sorts, how many Arduinos would I need for one four-button remote that could hook up to a computer wirelessly? What else might I need?
