Frequently Asked Questions

The included LDR is adequate for basic experimentation but lacks the dynamic range and low-light sensitivity of dedicated, premium light sensors. It’s a great starting point, but serious users might want to upgrade for more nuanced control.
The offset allows for a wide range of adjustments, but it’s not a true inversion. You'll get close to inversion, but the range is limited compared to a dedicated inverted output.
While it can handle bright light, a strobe's rapid on/off cycle might exceed the LDR’s response time, resulting in clipping or unpredictable behavior; attenuation is recommended.
