Arduino port manipulation – part II

In the first part I covered output of 8 LEDS using one port.    • Binary arithmetic and port manipulation on...   In this tutorial will use the port for input. Reading with one line of command the sate of 8 buttons. Showing the difference in time it takes to perform this test. Will also cover cool options of key combination, using the port output value. I used WOKWI great web Arduino simulator the code from the video is available at https://wokwi.com/arduino/projects/28... For WOKWI great article on time counting in Arduino https://blog.wokwi.com/how-to-measure... For more read about binary arithmetic and its practical uses in arduino https://playground.arduino.cc/Code/Bi... Some more info on ports in arduino https://www.arduino.cc/en/Reference/P...
