Question AnsweredPosted by @ollie_pmember since Jun 2026

Which resistor colour-code tools do you actually trust?

Apps that read bands from a photo keep confusing brown and red under warm light. Do people use a multimeter instead, or is there an app that works?

    Multimeter. Every time. The apps are a coin flip on orange/red.
