I don't feel like creating a userid on his website just to tell him this, but one thing he seems to have missed that may have caused some of his problems is that the ESP32 I/O pins are 3V and NOT 5V tolerant. Elsewhere in the article he seems to assume 5V levels (when he's talking about using PWM to output 2.5V from a 5V pin). With an ESP32 or ESP8266 when you need to interface with 5V devices you should use a level shifter.
- Athrunen 7y agoThanks for that information, but I learned that the esp32 is not 5V tolerant the hard way. ^^ Will fix the bit about the PWM in a second
- sprior 7y agoThat might be something good to mention in the article as something to watch out for. You mention checking the specs, but not that kind of issue with specs.
