I’m a newbie to the entire world of building electronics. I have something I want to build in mind but I have no idea where to start with choosing products. I’ve been reading the basics but I still feel somewhat lost. :think: I know how I want it to work, but I don’t know how to get there and so I figured I’d ask this forum.
Basically the process starts with say a silicone bubble, with a tube connecting from it to a pressure sensor. The goal is that when you touch the bubble/balloon, it senses the pressure change, and turns something on. I know I need an arduino board to go along with the pressure sensor, and possibly a daughter board (if there’s a better way, please tell me!). What I need it to do is gradually increase power to two objects (the power source likely being 2 AA batteries), and then of course stop before frying the circuits. I want to know if an integrated circuit would work, and if so, what kind?
One of the objects I want to power is a small air pump that would inflate another silicone bubble. The issue I’m having there is what to use to measure the air already inside, and then cut the power only to the pump/turn off the pump so the bubble doesn’t get too big or explodes.
I’d like to stay under maybe $300(I’m guessing here), and make it as small as possible.
Let me know if I need to explain something more. Thanks!
