  Hi Mike, not sure if I understand correctly what is the issue. Can you provide more information? Can you share screenshot of the project part and a sketch of desired behaviour? Is the issue about setting binary inputs sequentially which produces more logs to be written? Thanks. Cheers, Tomas

  Hi Mike, the mentioned sensor is just a voltage divider. The input impedance of AI on the Monarco HAT is 4.24kOhm, which naturally changes the ratio of the divider. Therefore if the resistors are 30k and 7.5k (as per the photo) and the external voltage is 13.2 V, the AI will read 1.09 V. And yes, it will work correctly if you rescale it in software. Though you'll loose some resolution. The input impedance of your multimeter is probably much higher and does not affect the voltage divider that much. Nice example for practicing serial and parallel connections of resistors. Kind regards, Jaroslav

  Hello, I've been a big fan of the Rex Control Virtual Labs for awhile now, it's a perfect tool to explain how PID loops are tuned. Last time I went to access them, however, the Launch button was greyed out and it says "For registered users only". But, there doesn't seem to be any way to become a registered user. Can someone please help me understand how to access these Virtual Labs again? It would be a shame if they were no longer available.

  Hi Richard, sorry, my mistake. You are right - both arrays have 11 items. But still the size need to comply with parameter n. Once you change it to 11 it should do the trick. Please, let me know. Cheers, Tomas
