Hrmmm wha oh now we are doing DHT as well :P
Would be nice if you shared a parts list that was specific and code that was specific to fit your specific hardware and links to items being sold etc watched the video the other night seems like seconds should handle just fine as I said it has to be done with a timer routine or it would not work you couldn't scrape time and report back fast enough but this code is of more interest to me as time is such a precious commodity and the need for it is far reaching in this day and age. The methods of handling automated things based off of time are important to most anyone trying to automate anything to a higher degree and keeping time is important and in this case even fun!
Any espbasic automatic throttles when it detects the green light errr forget what they are called but I knew people who had these installed in their drag cars something that would detect the green light and automatically hammer down on the throttle. Doubt they do the same for circle track but dunno?
Take care and enjoy,
