Arduino is an open source computer hardware and software company, project, and user community that designs and manufactures single-board microcontrollers and microcontroller kits for building digital devices and interactive objects that can sense and control objects in the physical world. The project's products are distributed as open-source hardware and software, which are licensed under the GNU Lesser General Public License (LGPL) or the GNU General Public License (GPL), permitting the manufacture of Arduino boards and software distribution by anyone. Arduino boards are available commercially in preassembled form, or as do-it-yourself (DIY) kits.
If you aren't using reentrant timer interrupts in your Arduino designs then you are it calls a function that takes a long time to Arduino Timer Interrupt.

Performing a function after x a restart of the arduino. I would implement a Timer class that keeps maxdelay; unsigned long lastset; ; Timer.
Video embeddedArduino LCD Clock, Timer, Stopwatch but it took me a LONG time to program. Arduino countdown timer Duration.
Watchdog Timer (WDT) The Watchdog Timer on the Arduino's microprocessor only has one source to drive it: If you want a very long sleep time.
I need help with an Arduino sketch, Repeat blink sketch for a specified time. (long duration, callback).
This is our original weather station kit. You will be surprised how much you can learn from it, such as how to connect sensors and write program to read the data, and display it on a LCD display. What you can do with this kit is only limited by your imagination.
In my heart I know we are stuck with the QWERTY keyboard but that doesn’t stop me wanting something different. I have thought about switching to Dvorak or Colemak key assignments but don’t want to deal with the problem of mental interference when I have to switch back to a normal keyboard.
Some time ago I saw people reverse engineering the infrared protocol of the Syma S107G toy helicopter and I wanted to get my hands on it as well. It is a coaxial helicopter, which means that it doesn\'t require a torque cancelling tail rotor. Yaw is controlled by using the speed difference to a second rotor underneath the main rotor, which spins in the opposite direction.
Neopixels or WS2812 what the real name is are amazing LEDS nothing is impossible, and i will proof that this year on this platform for YOU.
Connecting to the internet has not been easier, With the advent of the new IOT ( Internet of things) module ESP8266 its a breeze to connect your microcontroller and Arduino projects to the internet.
It turns out that it is quite easy to get Alexa communicate with Arduino via Raspberry Pi with Node-RED. All you have to do is installing two Node-RED modules and setup up a Node-RED Flow with Alexa Local and Arduino nodes. Here I have a project which has Alexa turn on and off two LED lights as a demo.
Sonar has always been a fascinating subject, the green dash board and flickering dots representing enemy planes and submarines has never stopped fascinating the hobbyist.

Long duration timer specifically made for use on tracking collars for small animals. Contains all the functionality required to test and implement a DC release.
This is my upgraded version of a Digital & Binary Clock using an 8 Digit x 7 Segment LED Display.
I like to give new features for usual devices, specially clocks, and in this case the use of 7 Seg display for Binary Clock is unconventional and it is an interesting and a different way of applying it.
