Yet another Arduino LED fade effect. Similar to Arduino – LED linear fade. However, this one is using logarithmic scale for the delay time. It gives a nice “breathing” LED light effect. With properly adjusted settings it can look like a sleep LED effect in a macbook. This example Arduino project lights the basic LED connected in series with … Read more
This article explains how to make an example Arduino project that lights the basic LED (connected in series with resistor to pin 11) using linear fade effect. To build a nice fade effect you need to know how to change the LED brightness, first. The complete code is also on GitHub, here. Linear Fade effect changes the LED brightness … Read more
This article shows how to use PWM (Pulse Width Modulation) to control LED brightness. Arduino boards based on ATmega328 have up to 6 hardware PWM channels mapped to pins 3, 5, 6, 9, 10, 11 @490 Hz (pins 5 and 6: 980 Hz). Thanks to Arduino API (analogWrite) we can easly control these PWM channels. … Read more

This is another blinky project. A “Hello World” program for the electronics. This version of “blinky” example is using delay function to make an onboard LED blink for roughly one second. The code is on Github, click here. Parts Required Arduino board (i.e. Arduino/Genuino UNO) Software This code is written in C++ and can be compiled using an Arduino IDE. All … Read more
Arduino is an open-source electronics platform based on easy-to-use hardware (Arduino boards), software (Arduino IDE), which allows to write programs and upload them to board (usually via USB connection) and an amazing community. In my opinion it’s a great tool to learn about microcontroller programming and for fast device prototyping. Arduino is not only for beginners. … Read more
The AVR is a modified Harvard architecture 8-bit RISC single-chip microcontroller. The AVR was developed by Atmel in 1996 and was one of the first microcontroller families to use on-chip flash memory for program storage. The AVR microcontoller is like a small computer – includes a CPU, some flash program memory, some SRAM and some … Read more
