Finally, the third sketch shows how we can use the interrupt pin on the PCF8574 to drive the interrupt pin on the Arduino LOW or HIGH to signal that one or more pins have now changed value (eg a ...

PWM pins are generally used in controlling output devices in Arduino projects.To send a PWM value to a PWM-capable pin like the Mega's D9, the easiest and most common way is by using the ...

His adapter board, which plugs directly into the Mega’s dual-row pin header, makes it easier to control these with an 8-bit chip that is running at 5V. There’s a couple of things that make ...
