Best you ask Joshua what he meant. But, I think that lower case is the executable and UPPER CASE is COMMENT. It must be tricky setting up the orientation of the servos and getting the code to the pins to match what is happening physically. Since my servo orientation was different from his, Joshua's code just happened to work better for a more sensible pinout (serendipity)! (i.e. His pinout did not work at all for me, so by trial and error, I found what worked by changing the pins instead of the code).
Thank you.Here is the latest incarnation of my tracker and my USB Power Bank is visible between the legs of my Jobi Gorilla tripod.
You can see in the picture a nine volt battery that I was originally using.I have decided that was too much power for the servos and I am now using a single rechargeable 18650 Li-Po battery USB power Bank.http://www.ebay.com/itm/301848407828?_trksid=p2060353.m2749.l2649&var=600660377758&ssPageName=STRK%3AMEBIDX%3AITI am waiting for delivery of a small solar panel which will keep the Power Bank recharged.I have decided that I can reduce the size of the light baffle I am using to segregate the LDR photocells to less than half the size shown and achieve the same results. The one now pictured is very photogenic, but once I have my solar panel, that is the main emphasis and the LDR baffle should not be so conspicuous.Have fun with your project, I look forward to seeing it.
Thank You! I could not have found a better example to model and build mine from than your excellent instructable. I am getting ready to add a light sensor to turn it off at night. I am still looking for the perfect solar panel to power my MacBook while I am off to Timbuktu.
