How to Use Milli in Arduino Code October 11, 2017 by Ryan Jones 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! Delay statements are ...
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...
Arduino is an open source prototyping board which is made around ATmega328P; it has 14 GPIO (general purpose input output) pins, out of which 6 pins has capability to do analogue functions, all the 14 pins has the capability to digital functions. A USB 2.0 type B placed right corner of...
the timer counts up to 256 clock cycles (28), which is 0 to 255. After reaching 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....
All of them have at least one built in timer, often several, as well as other goodies such as comparators, PWM modules and ADCs and more. These are all internal hardware units making it simple to create almost any project you can think of. All you need to do is decide what to use,...
Finally, the loop function updates LVGL and the EEZ UI before hiding the currently inactive calibration points by calling a helper function, and it also updates the counter label in each iteration:Copy Code void loop() { lv_timer_handler(); ui_tick(); if (get_var_hide_repeat_button()...
In this Arduino Tutorial we will learn how to use the DS3231 Real Time Clock Module. The DS3231 is a low-cost, highly accurate Real Time Clock which can maintain hours, minutes and seconds, as well as, day, month and year information. Also, it has automa
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 works by path timing measurement i.e. it works by assuming a 16MHz clock speed and measuring the number of assembler...
Running example of how to use the Arduino watchdog timer - bkolicoski/Arduino-Watchdog-Timer-Example
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...
