I’m going to lay this out with it being known that I am new to all of this small electronics stuff. programming I can do, wiring … well I’m asking for help aren’t I.
I play an online racing simulator, iRacing. I want to build an electronic scoring tower like they have at the race track. I am going to use 7-segment LED’s, shift registers, and arduino uno. I used this design as my starting point: http://www.sqlskills.com/blogs/paulselec/post/Arduino-cascading-shift-registers-to-drive-7-segment-displays.aspx
Here is my concept:
I have someone who was helping me get the board put together. Here is the design I gave him:
Here is the design he sent back: http://nuzumphoto.com/Unused/iracing/scoringtower/Tower3-1.pdf
The LED’s used: https://www.kingbrightusa.com/images/catalog/SPEC/ACSC56-41SRWA-F01.pdf
The Shift Registers used: http://www.nxp.com/documents/data_sheet/74HC_HCT595.pdf
So now I have the actual board in my hands and have it hooked up. ran the exact program from the sqlskills.com site. nothing. When i initial plug in the board to USB the LEDs flash red across them. Like it’s clearing them or something. But the program does nothing. No reaction at all from the board.
Photos of the board and setup.
Anything glaring that I missed between the original design and mine. Any thoughts at all?
