Arduino had an IAM solution based on open-source tools, but struggled to keep it updated, with maintenance alone costing nearly two full-time employees, or $100,000. This solution also increased security risk, as any upstream security bug in the open-source tools would inevitably trickle down...
Avoid off by one errors - very easy to miss. Count up or down (and use the loop variable inside code). Find out where you can use for-loops. Access array data with a for-loop. The 'for loop' is one of those bread-and butter functions that you will use all the time in your co...
You see, delays pause your Arduino's program, making it incapable of doing anything else in that time period. Instead of pausing our entire program for a specified time, we will learn to count how much time has passed before completing an action. This, of course, is accomplished with our...
pulseIn( <pin>, HIGH, 10000000UL); // 10 second timeout. interrupts(); Note:You can use pulseIn with interrupts active, but results areless accurate. Using Arduino PulseIn The following code expects a signal on pin 7 and uses the pulseIn function to measure it, and then reports the resu...
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
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
During this process, the touch input handler does not pass on touch events to LVGL, meaning that the user cannot interact with UI elements during that time. Once done, the function advances the calibrationStep variable. When it exceeds three, the calibration process is done, and the code ...
In this Arduino tutorial we will learn how to use the HC-12 wireless serial communication module which is capable of making a long range wireless communication between multiple Arduino boards, with distances up to 1.8km. For this tutorial I made two basi
And if you need to edit that decimal, then you may want to check the position of the ibeam with the SelectionStart property for that TextBox control to see where it is inside of the existing text number value.Cheers :)If a post helps you in any way or solves your particular issue,...
