The Project: To indicate whether a weight on the scale is over or under 8 Oz.
The basic plan is to hook up a scale to an Arduino uno and use an LED to indicate if it is above or below the ideal weight.
My current setup is a Tor Rey L-Pc 40L scale (TORREY L-PC SERIES USER MANUAL Pdf Download | ManualsLib) which has an RS-232 port. I have connected the RS232 port to a MAX 232 Converter.
I have taken the rx line and connected to pin0 on aruduino uno and the V+ is connected to 3.3 and gnd to gnd.
Using this code
I get this result
How do I get to some data that I can sort out. I only want to know the active weight on the scale? Many thanks!
