![]() This can allow the pump to have separate functioning modes such as high and low speeds or small and large volumes. It can alternatively be used to select between the controller’s codes. ![]() As a result, this will allow the user to adjust the flow rate during operation without the need to reconfigure the microcontroller’s code.Īn addition of a liquid crystal display (LCD) screen can allow the user to view details about the pump when running, such as the currently set flow rate or the operating time remaining.įurthermore, a toggle switch can be included to override the controller’s code and act as a safety off switch. The knob can be rotated to adjust the input signal to the microcontroller which can automatically equate to changing the initially set flow rate value in the code. For example, the electrical setup can be modified to incorporate a potentiometer knob. ![]() Additional design improvements can also be integrated into the design’s electrical setup that can improve the pump’s convenience and provide additional features.
