My Projects
This is a class project for Measurements. This includes a geared dc motor turning a cylinder immersed in a viscous fluid. The spinning motion of the cylinder acts on the inner surface of the cup, causing the cup to turn slightly. This force is counteracted by a spring attached to the bottom, and is measured by a potentiometer also attached to the bottom. The viscometer provides a real time display as well as outputted values via the USB port on the Arduino Uno micro controller. This system will allow you to set the testing speed and begin the test with menu navigation performed by momentarily clicking (option scroll) and long pressing (option select) a single button.
This project also includes a fully 3D-printed frame as well as a carrying handle, spare fluid, an attached power supply, and a cable wrap for the power cord.
