Hi V-nath: HI, I got just ONE questions for you ?What if the voltage is 24 v DC to drive the LED's?Mine is a jumbo sized display of 3 digits in Common Anode Configuration. I have put seven transistors (2N2222's), between the cathodes (seg. A to G) and GND. Every base of these transistors go to Q0 to Q7 of the first 74H595 through a 1k resistor.Another set of 2 transistors is arranged between the +24v dc and Common Anode of each digit. The first transistor is NPN and the second is PNP, so that when the Q0 of the second 74H595 goes high, the anode of that particular segment goes high.Is my understanding correct and technically feasible for my jumbo display ?I appreciate your inputs.............email@example.com

Hello tractorman 1960, A solar tracker for a 7 kw would be much easy to implement with a slew ring drive. I plan to build one this summer with a 5 kw panel (20 panels of 250 w each, arranged in 10 panels on either side of the slew ring drive).
Great job. Keep up the good work. Loved it.
Great job elisalame, I am learning Arduino now and your tutorial was of great help. Keep up the good work.
