@zander FWIW, I posted the Serial Monitor message I'm getting as a query on ChatGPT. Below is the conclusion. I can post the more detailed answer if a...
@zander Thanks, Ron. This is a SparkFun Pro Micro - ESP32-C3 which, so far, I've had luck with. Your right, a similar Adafruit C3 board I was never ab...
Hi Ron, Using several of your tips, I finally got the Internet Radio sketch to work on the Arduino Nano ESP32. The solution: >Put the Nano ESP3...
@zander Thanks for your efforts. I gather, however, that you did not actually have a MAX98357A DAC/audio amplifier board wired to the Arduino Nano ESP...
@zander Yes, those pinouts are from the link I posted. I used the Arduino Nano ESP32 pin 7 for the MAX98357A I2S BCLK, pin 8 for LRC and pin 9 for ...
@zander Yes, I used the same code as Bill and when I used a ESP32-WROOM-DA processor, I used his wiring. As I have said, with that processor, Bill's c...
@zander Here is a link to Bill's article "Sound with ESP32 – I2S Protocol". The section of the article I am referring to is "ESP32 Internet Radio" and...
@zander Yes, the board which isn't working with Bill's I2S projects is the Arduino Nano ESP32 which Bill has featured in another video. Here is a li...
@zander Thanks, Ron, for your reply. In fact, you're right, Bill's I2S projects don't use the Nano ESP32, but rather a different ESP32 processor. When...
@davee Here is more of the coil specification. Since even at a fixed ambient temperature (20°C) the coil resistance can change due to self-heating,...
@davee Thanks for your comments. Yes, the coil/resistance/temperature spec seems strange. Other relay specifications show this coil specification a...
@will Thanks, that article (and others it led to) help explain the issue of coil resistance change with temperature.
Thanks, Will, that's useful. I'm guessing "Max pickup voltage" is what the DigiKey article calls "Pickup Voltage" which I would understand as being ...
