Delay statements are great and all, especially for their simplicity, but they can really put a damper on things when trying to multitask your Arduino. Forget delay and hop on the millis() train!
Arduino Strings have been getting bad press due to the extra memory they use to make copies and the memory fragmentation they can cause. These can eventually consume all the available memory and cause the micro to miss-behave and reboot. This tutorial will show you how to avoid these two me...
Running example of how to use the Arduino watchdog timer - bkolicoski/Arduino-Watchdog-Timer-Example
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...
255, the counter goes back to 0. This is called rolling over. When timer0 first rolls over, a rollover bit will be set, and this can be used by the programmer if desired. Timer0 can also be set to operate as a 16-bit timer, which means it can count up to 65536, or 0 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 the task is finished, the Arduino will resume what it was doing before being ...
In this tutorial you'll learn how perform daily tasks with the Arduino. We're going to turn an LED on and off at a specific time of the day, everyday.
Using Arduino PulseIn The following code expects a signal on pin 7 and uses the pulseIn function to measure it, and then reports the results to the serial interface. The timeout value is set to 3 seconds and the code also reports when that timeout fires indicating that no signal is presen...
However, the wall light switch I have is a 3-gang switch. The first switch works well with Zigbee_On_Off_Switch, but how should I get the second and third switches to work? I am new to Zigbee and am having difficulty understanding how to set it up. Sketch #ifndef ZIGBEE_MODE_ZCZR...
The program starts with the top-left calibration point visible and the counter set to zero.The Arduino sketch contains the same essential functions discussed in the previous article. The first of the four functions is the custom display flush implementation, which is the same as before:...
