last_time = millis(); } Now, As you twist the knob, you'll notice information appearing on the Serial Monitor, much like what you saw in the earlier code.※ NOTE THAT: If you use the interrupt, you need to connect the encoder's CLK pin to an Arduino pin that can handle ...
Most board support packages use interrupts to advance millis() and micros(), and with these BSPs, millis() and micros() return incorrect values while interrupts are disabled. Although some BSPs (like the ones provided by MCCI) provide real time correctly while interrupts are disabled, this ...
if (millis() - lastReadingTime > 1000) { // if there's a reading ready, read it: // don't do anything until the data ready pin is high: if (digitalRead(dataReadyPin) == HIGH) { getData(); // timestamp the last time you got a reading: lastReadingTime = millis(); } } //...
With that said, it looks like you take what would have been an analog output and convert it to digital to then provide a readable serial output. I would like to output an analog (or PWM) 0.0 – 5v (range 0 – 45 or 90 degree tilt) signal that I can feed into another device. Wou...
Learn how to request date and time from an NTP Server using the ESP32 with Arduino IDE. Getting date and time is useful in data logging projects to timestamp readings. To get time from an NTP Server, theESP32needs to have an Internet connection and you don’t need additional hardware (...

However, to keep things clear we’ll use the terms “sender” and “receiver” or “master” and “slave”. ESP-NOW Two-Way Communication With ESP-NOW, each board can be a sender and a receiver at the same time. So, you can establish two-way communication between boards. For ...
By default, plotly assumes that x is millis() and automatically converts the x to a real-time timestamp with the timezone "America/Montreal" on the server. To disable this, set convertTimestamp to false, e.g. ``` sh plotly graph = plotly("your_plotly_username", "your_plotly_api_ke...
