It probably won’t take long working with the Arduino before you will find a need to use hardware or timer interrupts. Interrupts can help when you want the Arduino to do more than one thing at a time. Interrupts will make the Arduino stop what it’s doing to perform another task. Once...
Different types of Arduino board have different numbers of interrupts pins e.g. Arduino UNO have two interrupt ports and Arduino Mega2560 have six interrupt ports named as INT1,INT0. On the software side create sleep mode for Arduino and use a timer base interrupts which would internally be e...

All general-purpose input output pins can be used as external interrupts. External interrupts are very useful. When you want to monitor change across any pin, you can use this pin as an interrupt instead of repeatedly monitoring the state of this pin. PWM GPIO pins All general-purpose input ...
Arduino For Loop - How you can use it the Right Way. Copy the code into the Arduino IDE. Compile and run the program. Start the serial monitor to see the output.void setup (void) { Serial.begin(9600); Serial.println("Arduino for loop"); for (int i=0; i<10; i++) Serial.print...
Taming Arduino Strings -- How to Avoid Memory Issues: Update 9th July 2021 - Added link to fixed versions of Arduino Strings files. Normally not needed. Quick Start For small sketches with a few Strings, just use them as convenient. For small sketches wi
Change the above code to use pulseInLong() to check (not forgetting to comment out the interrupt control functions). Arduino PulseIn Problem The problem with pulseIn is that you really want to use it with interrupts turned off for maximum accuracy. It is written in fixed assembler code that ...
I am currently working on a system that you can use to add to the drone in order to measure the voltage of the battery safely and send it back to the controller. At the moment it is best to use timer and to measure the voltage of the battery when you land. This is to avoid the...

All this is really important when it comes to practical applications: you need to make sure you use the right magnet and that it moves in just the right way to actuate your reed switch. If you're using a reed switch as a counter, for example, it should actuate only once each time th...
