I need a programmer to write code for a Arduino or ESP32 touchscreen (or similar) which will control a pump to dispense fluid.
The touchscreen needs to be used to choose a recipe and then using this data switch a relay for a given length of time which in turn will control a 230v gear pump.
The screenshot included shows the basic functionality required.
The pump will run at 14 litres per minute and the fluid density is 0.92g/cm³ so the dispensing time can be calculated from the KG value selected.
A calibration factor is included for improving accuracy if needed.
I require the programmer to recommend the computer and touchscreen suitable for the project.
