an Arduino Weather Station needs timestamps in recording weather data. Another example is for an Arduino digital clock or calendar. Arduino-based clocks use the current time as a timer for reminders or to execute a scheduled command via the Arduino...
I like the MSP430, and i like to use CCS instead of Energia. It might take a lot of time, but Energia and the Arduino IDE for the Atmel MCs too hides what is really Happening in the MC itself. I want to understand what the things do. I am glad that you give me hints what othe...
Usually, you only use two, which are timer-interrupts and hardware-interrupts. You can learn more about the other types of interrupts and when the microcontroller (MCU) raises them in the datasheet of your Arduino's microcontroller.Timer-interrupts are a fantastic way to avoid using the ...

Arduino is generating a modified sine waveform of 5V which is amplified to a level of 12V using L293D ic. Battery voltage is monitored every 20ms using timer interrupt. Step 2: MAKING POWER STAGE As the inverter output power is 600VA and it is 75% efficient so the input current at full...
When an object moves, it needs to pass the first IR sensor. While the object passes this first IR sensor, the first IR sensor signals Arduino to start the timer. Later the object passes the second IR sensor, and while passing the second IR sensor signals Arduino to stop the timer; this...
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,...
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
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 ...
