Hey Chris,

We’re planning on using an Arduino-Uno via Mworks-StandardFirmata to trigger a brain stimulator, so we wanted to see if anyone has measured any lags in the triggering of the arduino pulse? Ie - if we send an update to the screen and set the firmata variable to 1 simultaneously, has anyone tested the lag: or any similar test?

Hi Travis,

I did do a timing test not long ago for another MWorks user. Please see [this discussion](https://mworks.discourse.group/t/alternative-to-nidaq-for-ephys-setup/110/2).

Also, as I mentioned in that discussion, the Arduino Uno probably isn’t a great choice. I’ve been recommending the [Arduino Nano 33 IoT](https://store-usa.arduino.cc/products/arduino-nano-33-iot-with-headers), which uses a much more modern and powerful processor than the Uno. Unfortunately, the Arduino store doesn’t have them in stock at the moment. Although I haven’t tested it personally, the [Arduino Zero](https://store-usa.arduino.cc/collections/boards/products/arduino-zero) should also be a good choice, and it is currently in stock.

Cheers,  
Chris
