One minor point of critique: Explanations on absolute programming basics (like: What is a variable, what are datatypes, basics about functions etc.) are best explained in a seperate, dedicated video. Otherwise, it makes the video feel a bit tedious despite the well structured nature of this video. Particularly unpleasant for people with some level of programming experience. Other than that, this video was quite helpful.

Thank you. This video is the first step in my next project: Calculating the RPM of my stepper motor. The Arduino code that runs my stepper motor driver, turns a Pin connected to the PUL pin of the Driver to HIGH, has a delay of 500, then turns the pin to LOW. This code loops to run the motor at a constant RPM. This video will help. But if you have any suggestions/video recommendations to calculate the RPM, let me know. Thanks!

1:40 Correction. Most Arduinos use a ceramic resonator. This is not as accurate as a crystal. Generally, a crystal is needed for things like serial communication in order to control the baud rate. The crystal pictured in the time stamp is used for this purpose. It is the crystal for the USB to serial converter. In this case the converter is another AVR microcontroller, an ATmega16U2. The crystal resonator used for the ATmega328 is pictured just below "ITAL" in the Made in Italy text. -Jake

Nice video, but there are some inaccuracies: 1. The timer/counter does not start counting “as soon as power is applied”: it starts counting when initialized by the Arduino core (see the setting of the TCCR0B register in init(), in wiring.c). Admittedly, this happens very shortly after power is applied. 2. The timer/counter does not overflow after 49 days: it overflows every 1024 µs. The 49.7 day rollover is for the millis() count, which is a different thing. 3. millis() does not give the running tally stored in the timer/counter: it returns a count of the timer/counter overflows, plus some correction to account for the fact that the overflow happens every 1024 µs instead of every millisecond. The micros() function, unlike millis(), does make use of the running tally kept by the timer/counter.

Code as below and I want sensorVal=1 for 5 min int =rcwlPin=2; int=sensorVal; cosnt unsigned long Interval=1000*60%5; unsigned long PreviousTime=0; void setup(){ pinMode(rcwlPin,INPUT); Serial.begin(9600); void setup(){ sensorVal=digitalWrite(rcwlPin); millis()=unsigned long CurrentTime; if(sensorVal==1){ if (CurrentTime-PreviousTime>=Interval){ sensorval==1 PreviousTime=CurrentTime; } } else { (sensorVal==0) } Serial.println(sensorVal); ) I upload this sketch, but not getting desired result. Kindly resolve it. Thank you

and my problem is "I'm making a digital clock [7-segment] using AT89s52 (NO RTC) but the time drifts about 5.6 seconds in every hour!! and this At89s52 microcontroller doesn't have any function like millis() inside AT89s52's IDE(Microvision Keil software), and a book suggests to play with the ppm and fix the error.But, yet the problem is At89s52 is not like Arduino " BTW I'm using a 16MHz crystal with this microcontroller and using timer_0 to generate a 25ms delay and using interrupt_1 to count that 40times so that there will be 1 second completed, but that's not the problem I guess.. I just need help.. .😎😎

I am a dumb engineer, but since you have quantified the deviations, why not make your seconds 5.6/3600 x frequency shorter? It is quick and dirty, but I think given the hardware, there is not much else you can really do. There are too many sources of error at play.

Unsigned long. It is an explicit cast of the number 3000 into the unsigned long format, so that you compare equal data types.
