Using Chronos Analog Input with our Slider Accessory [34381]

Warning: Improper use of Chronos may void your warranty.

A Webinar covering Analog Input can be found here: E-Prime 3.0 Webinar: Analog In Using Chronos.

The ChronosSlider experiment was created to demonstrate the use of our Slider Accessory (https://psychology-software-tools.mybigcommerce.com/chronos-diy-response-bundle/). When run, the experiment displays the value of the Slider in real time on a 1 to 10 scale as well as the raw value.

Note that using .Filter results in smoother values and consumes fewer resources on the machine running the experiment. Slow (e.g.) 0.98 filters take a few ms to converge on the right value but are steady. Medium (e.g. 0.9) filters take less than a millisecond but may jitter a bit.

Analog Input channels 2 and 3 produce less noise. Channel 1 has a marginal increase in noise, and its range is effectively restricted to 3V since it is protected. Do not use Analog Input channels 2 and 3 (unprotected analog inputs) if any voltage over 3.3V is provided as this may damage Chronos (or at least the analog input) and void your warranty.

If using an Analog Output to power the Slider, you should use Analog Input channels 2 and 3 as the voltage is 3.3V. In the image below, Analog Input 1 is used. However, this can be easily changed to Analog Input 2 and modified in the experiment simply by changing the ADchan Constant to "2" in the StartLoop InLine.

NOTE: For more detailed information, review the StartLoop InLine.
