In this tutorial, we will learn how to use port expanders by building a project using the MPC23017 port expander to create two additional 8-bit ports and read and write to them using I 2 C on the Arduino. We will create some running lights and use bitwise actions to read input ...

bitRead () gives wrong answer Arduino UNO R3

Web1. I am trying to read from a quadrature rotary encoder using an Arduino UNO R3. This is done by connecting the encoder's channel A pin to the Arduino interrupt 0 pin (digital IO pin 2). Inside the interrupt routine I then read the value of channel B (connected to digital IO pin 8) to determine the direction of rotation. WebMay 5, 2024 · Extract the value of one bit from the byte. Output HIGH or LOW on an output pin according to the value of the bit. The bitRead () function only does the middle step for you.
