Keypad is a class. Therefore to use multiple Keypad, you must create an instance for each of them. In the example above, the Keypad instancekeypad) was bound to the digital pins 2, 3, 4, 5, 6, 7 and 8. To add a Keypad bound to digital pins 9, 10, 11, 12, 13, 14, 15 and...
Here in part four we will connect a type a Hd44780 type LCD display and learn how to enter data and manipulate character date and strings. In addition to the LCD display we will scan a keypad, use hardware interrupts, all connected through a single PCA9555 module. In addition I'll revea...
ok so i am new to arduino. i am trying to have one button turn on the led witch is in pin 13 and another button to turn it off but im having problems. when i press the button it turns on when i let off the button it goes off. here is my code so far. const int buttonPin ...
In this tutorial, you will learn how to use the AnalogRead function ofArduino. If you are working on a project, where you need to measure the analog voltage or analog sensor value which gives you output in the form of voltage, then you need to use ananalog to digital converterof Arduino...
