Parts List. Any way to make money off your Arduino? Personally, my choice would be to teach people how to use it. Then, depending on the cost of the class, give them out to the students — preferably with a small kit. Use it as the heart of something you make that some people want to buy, then build and sell those things. You can’t compete with mass manufacture on price, but because you can only build a small number of devices anyway, you can find a niche market that is just too small for a mass-manufacturer but not too small for you. Ultra-niche markets are generally expecting to have to pay more than mass-production prices anyway because of that, so it can work out nicely.
