Version 2 Arduino Code

(1/1)

SouthernAtHeart:
Hi, I do a lot of arduino projects/tinkering, and would like to build this little tachometer from scratch.  I see your original code that you first tested it out with on a 16X2 LCD & an Arduino UNO.  Do you have the code you use for the 7 segment kit?  I'm not sure which way I'll go yet, I've worked with 16X2 LCD's a lot, but never the 7 segment type. 
One perk I see for the 7 segment display is it looks like it might be clearer to read.
I thought about using a tiny 8X2 LCD character display, and then I could have one of the two lines display either "FORWARD" or "REVERSE", to indicate the spindle direction. I think an 8X2 would fit inside the existing box in the same location.

ps.  OLEDs are supposed to be very clear to read:  I see CrystalFontz has this one that is almost identical in dimensions to your V2 board, so it would fit nicely inside the enclosure.

Hi,

In blue the 7-segments are very easy to read. Two customers have informed me they use the 7-segments now vs the power light to identify if their mill is indeed turned off (their machines are in very bright areas). Having worked with OLEDs I would say that they would have similar visibility to the blue 7-segments (red/green are harder to see).

The version 2 of the tachometer does not use Arduino code and I do not provide the source
