![]() ![]() Everything was working fine until I typed code for the servo motor ( under if line). I'm using 2 codes combined from 2 different videos. ![]() error: WProgram.h: No such file or directory is what I got in return. Arduino - 'setLocked' was not declared in this scope on: October 26, 2017, 05:22:32 pm I'm a beginner in Arduino and I am trying to make a safe using a keypad, lcd and servo. If you are using 1.0 or above include Arduino.h instead (the header file was renamed in that version). 0023) you need to include WProgram.h in your. This could for example be to change the PWM value of the fans, getting the temperature from a sensor and so on. If you are using a version of the Arduino software prior to 1.0 (with a version number of the form 00XY, e.g. Maybe this is a newbie question, but what if I want to execute more code in the loop than just counting the RPM. I as suggested by both cattledog and Larry D I have made the code based on the "blink without delay" template, which is working fine. Using delay to collect interrupt counts for one second is not good practice and you should follow Larry D's suggestion of using the "blink without delay" template. Serial printing also requires interrupts to be enabled. h:149:42: error: fabs was not declared in this > scope > ticksdc (uint32t)(ceil(fabs(tmp))) > /usr/avr/include/util/delay.h:149. Thanks for all of your replies I really appreciate it.ĭelay() requires interrupts from Timer 0 to work, and you are entering the body of the loop after noInterrupts() which has disabled the interrupts. if running in debug mode then set the delay time to 1 sec Please let me know if you need more information. I have read Gammon's post on interrupts, but I still don't understand what I'm doing wrong. However, after I have calculated the fans' RPM I would like to delay the loop for 60 sec but the delay() function doesn't seems to work.Īny suggestions on how to get this to work are greatly appreciated. This works as it should, the fans' RPM are calculated correctly.

My script is based on this tutorial ( Reading PC Fan RPM with an Arduino). I have two PWM fans where I read their RPM with an Interrupt Service Routine. ![]()
