Hello,
I recently completed, with some assistance from Coder27, Bill Abbot, Tony, and Mark Beckett the first part of my project ( http://www.element14.com/community/thread/23967?start=0&tstart=0 )
Now the second part - I am wanting to add a small 16 x 1 LCD to finish up my project (see coding below that I will be using)
I would like the LCD to simply show which direction a servo is pointing (as in degrees, such as 0°, 90°, 180°, 270°, or 360° or anywhere in between 0° to 360°)
Please be advised: I do know that arduino 1.0.4 has the LCD Scroll example, but I am sure I dont need the entire code they have. Also, my LCD is only 16 x 1, not x 2.
Thanks,
~Anna
