The interrupt mode LOW doesn't seem to be implemented on the ArduinoR3 component.
I've created a test circuit here to demonstrate the problem:

Is this something that will be rectified?
Thanks for taking a look,
Miles.
You are correct that LOW is not functional. It is disabled currently because if an input is LOW at the start of simulation, the simulator misses the initial LOW interrupt condition and won't fire it until the input toggles HIGH first. I'm taking a look at how to get this to work now.
The LOW interrupt on the Arduino fires continuously as long as the input is LOW. For that reason, it is not used very often in practice. Would a FALLING interrupt work what you want to accomplish?
Hi,
Any chance an official response could be made to this post? it is still a problem and something that I would assume could be fixed easily.
Thanks,
Miles
Hi Joshua,
Thanks for replying to my post. Unfortunately, in my project, the FALLING interrupt can't be used; I want to put the Arduino in a very low power sleep mode, (SLEEP_MODE_PWR_DOWN), and then wake it using an interrupt. According to the documentation (https://playground.arduino.cc/Learning/ArduinoSleepCode), In all but the IDLE sleep modes only LOW interrupt trigger can be used. In my project, I'll be setting the interrupt pin as an INPUT_PULLUP, and connecting it to ground via a push button. It would be great if I could simulate this in Tinkercad Circuits.
Thanks,
Miles.
Miles,
Unfortunately, sleep modes are one of the other few things not supported by the Arduino simulation. Those two things are on our list to address as time permits.

Thanks for your prompt response, much appreciated.
