Look for the package titled "LiquidCrystal Built-in by Arduino, Adafruit". In the search bar of the Library Manager enter "liquidcrystal". Go to Tools -> Port -> select the port where the Arduino is connected to.ī) Add Liquid Crystal Display library: In the IDE go to Sketch -> Include library -> Manage libraries. Go to T ools -> Board -> Select Arduino/Genuino Uno. The IDE can be downloaded from this LINK if you do not have it. The steps below include the process of making this addition to the IDE.Ī) Connect the Arduino to your computer and open the IDE. You will have to add them to your Arduino IDE to use the code.

The code for this project makes use of customized libraries and header files. Work on the inside of the rectangle instead of the lines as it may be a bit difficult to cut in a straight manner with this bit on the drill.ĭ) Next, use a hand file to remove the excess material and shape the rectangle to the required size.

Since this a small job, we will use the bit on the hand drill rather than a drywall cutting machine. Center a 98x40mm rectangle on the cover.ī) Put the piece in the vise and drill a 3.2mm (1/8") pilot hole in the rectangle that was marked off.Ĭ) Use this pilot hole as the start point for the 3.2mm (1/8") drywall cutting bit. It has to be modified for the pH meter.Ī) The LCD is placed in the top portion (cover) of the enclosure. The housing used is an ABS plastic enclosure. Safety : Remember to take care when handling tools/machinery and to wear proper safety gear such as goggles, gloves, and respirators. This meter was developed on a Windows computer. Readings will be displayed on a liquid crystal display (LCD). In this project, we will be making a benchtop pH meter using the Gravity analog pH circuit and probe from Atlas Scientific and an Arduino Uno.
