Hello, We are a group of students and we have a project that we want to develop with arduino.
There is a part we need in this project, but we haven't found it yet, the task of the part in the project;
checking that a circular structure is held by hand.
So we actually need a part that we can control with arduino, such as touch & contact detection. And this piece needs to have a flexible structure, because the place it will be placed on is in a round structure (like a bagel). How do we detect the situation when we can wrap around the circle and when we hold&contact? Which product is suitable? We need your help. resources are very limited. thank you. (the entire sensor needs to be touch sensitive because the gripping action can be done from any part of the circle).
They make capacatance sensors (buttons for example) that you could modify and use. Some micros have this ability on their port pins, some do not so choosing the part will be a good exercise because you have to factor in cost between a sensor and micro board or an all in 1 board. Have fun with this. Feel free to come back and let us know what you have come up with or any questions you may have. You should put together a specification of what it is expected to do and what parts you will need to accomplish it. This can be done on an individual basis then combined in a group session(s). See if you can get a copy of the Arduino Cookbook maybe from the library, your solution is in there and a lot of great ideas as well.
