PROJECT 02 TRACK POLARITY INDICATOR
Posted: Fri May 25, 2018 4:36 am
Nothing like being side tracked, had a PM from a member regarding what to buy.
But they also asked about using an Arduino to check the track voltage polarity on a DC system as to which is positive and which is negative.
For the Arduino this is a pretty easy task, but would be a massive overkill, but if you add getting the actual track voltage and display this on an LCD or 7 segment display then it would become another nice little project that would be a handy tool to have on hand.
And with a PWM system could give the frequency, the duty cycle, the average voltage, the peak voltage, the min voltage, all on an LCD screen.
So I shall put this on the list of projects, as I could use one myself.
So with the above question I have put together a small quick simple device to do the job and put it together as Project 02 TRACK POLARITY INDICATOR
I have attached the circuit and some photo's of a simple device to check the polarity of the track voltage, using 2 red LED's and 2 green LED's, and 2 resisters. It is assembled on a piece of circuit board so the LED's sit over the rails the green LED indicates the positive rail and the red indicates the negative rail.
