Project 32 – Digital Barograph

Now that you can hook up the SCP1000 and obtain data from it, you are going to put it to some use. This project is to make a digital barograph, which is a graph of pressure over time. To display the graph, you are going to use a GLCD (Graphic LCD). You'll learn how to display graphics as well as text.

Parts Required

The parts list is identical to Project 31, with the addition of a 128×64 GLCD, an extra resistor, and a potentiometer. You are going to use the glcd.h library so the GLCD must have a KS0108 (or equivalent) driver chip. Check the datasheet before purchase.
