How to make a weight sensor that turns off a pump at a very precise weight? Answered
Hi everybody! I'm building a coffee maker, well trying to at least, and one of my goals is to have it be that that placing your cup on a sensor pad will read the weight of the cup and then activate a pump to pour in the appropriate amount of coffee to top it off. My thought was that the user would set up a profile when they set up the coffee maker so it knows how much their cup weighs, and this would be stored on a small inboard computer like the raspberry-pi, then placing the cup on the weight sensor would measure the weight of the cup and run a simple equation to determine how much coffee is needed and how long to run the pump to dispense that amount. Unfortunately i'm really new to all of this and at a loss for where to start with programming the raspberry-pi and how to connect it to a pump or a weight sensor, any advise or tips on where I can learn some of these skills would be appreciated! Thanks!
