@kirk @Inq is perfectly capable of answering your question but I don't see him online so I will take the easy one.
const_float is not a valid keyword. const is and float is, they mean constant (can't be modified by program code) and float means a floating point number. Those are numbers with . in them generally like 3.14.
Flat 4 strand cable as you call it is available from all the usual places, Amazon for speedy delivery but highest price, AliExpress for long delivery but cheap, e-bay or bang good in betweeen the other two plus any one of numerous electronics supply houses, just google it.
Arduino says and I agree, in general, the const keyword is preferred for defining constants and should be used instead of #define

@kirk @Inq FYI Try testing with @Inq's amended sketch. We know it works, if yours does not then you have hardware problems. Change each piece of hardware while running the known working sketch until you find the problem. Now you can try to move forward.

Hi, The code is designed to turn the motor-that was the plan anyway.

Do you know a good source for flat 4 strand cable? I want to connect straight from the Arduino digital output port to the driver.
see Amazon

@zander For anyone interested I found a source for cables with Arduino terminals on EBAY. I pasted the link below.

@kirk I am not sure what you bought, but the price is high and it does not appear to be a complete set.
The set I bought is 360 pieces total, for $11.55
3 x 40 Male to Female
3 x 40 Male to Male
3 x 40 Female to Female

@kirk What is an Arduino terminal?

@zander Re: Arduino cables. What I intended to be ordering was two male/female cables 4 strand x 50 cm. They are on their way. You may be right I don't order from EBAY a lot; so I didn't know if that was a good price. I don't really need that length at the moment; but I will need to set up for outdoor testing.

@kirk This is a complete set, Male to Male, Female to Female, and Male to Female. 40 wires per bunch, 3 bunches per type. Ends are male and female dupont connectors. I have never heard of Arduino terminals.

Hi Ron, I located the problem, aka my mistake. I had switched between a couple of different types of driver boards and assumed the Vcc and Ground were in a certain location. I attached a photo. As you know there are different styles of board that differ somewhat on Vc placement. In the future I'm always going to check continuity between pin 16 of the Darlington chip and the output pins as well as documentation if I can find any. Any suggestions?
Thanks again for your help. I will provide follow-up as my crazy project proceeds. Kirk
