Of course, there are cases when tight timing does matter and an Arduino won’t make the cut, but in that case, it’s a job for the embedded engineer. Use the HAL, Luke!

If you take a look to the circuit scheme published in the Alphanumeric LCD with Shift Register on Arduino you can see that there is the pin number 9 that is NC (not connected). In the shift register ...

This article should acquaint you with basic Arduino programming and show you how to write programs that interact with objects in the real world. (A mandatory disclaimer: the last time I really studied ...

In this article you will learn how to make a digital clock using Arduino and the DS1307 RTC IC. What is DS1307 IC actually? Well, it is a Real Time Clock (RTC) IC that is simple to use, low cost and ...

In the Leonardo, an op-amp between the ATmega pin and the led means that loading is minimal and the pin can easily be used as an Arduino input. This buffer is missing on the Micro, which means even ...

Learn how to connect multiple buttons to just one Arduino pin using clever wiring and resistor techniques. Perfect for compact projects, keyboards, or when using small boards like the Nano or Pro ...

The statement analogWrite (3,i); is how PWM is implemented in the Arduino. Pin 3 will output a square wave with a certain duty cycle. A value of 0 means a duty cycle of 0%, or completely off.

Rotary encoder decode for Arduino It is amazing how many Arduino programmes for decoding rotary encoders start with something like: “I looked at all the available rotary encoder sketches and none of ...
