WebSep 30, 2024 · A yellow LED will blink at a rate of 500 milliseconds, and a red LED will blink at a rate of 5 seconds. The typical method to blink LEDs uses the delay() function, but that won’t work in this case so we need to use a timer interrupt to control one of the LEDs. Here are the parts you will need to build the project: Arduino Uno; Jumper wires ... WebYou will need to alter the pin / bit tied to the backlight led. To do that you will need to be able to read the state of all the pins on the i2c expander. That can be done by reading back the pin state from the i2c expander or to hold the pin state in a buffer. Once you know the pin state, you can OR or NEG it to clear or set the pin.
