Automatic titration
Summary
We will automate the process of titration. It is a device widely used in Chemistry for measuring concentration of acid or base.
Plan
We plan on using Arduino Nano as a brain for a display (to graph and calculate data), a keypad (to enter initial volume and concentration), a pH Sensor to collect the pH of the solution, a solenoid valve to mix the liquids by constantly opening and closing, and a powerful ADC to receive more correct voltage.
