After learning about SSL/TLS certificates and how to obtain them using Google Chrome, let us program our ESP32 board in Arduino IDE for HTTPS requests. We will look at two different Arduino libraries to generate the HTTPS request. First, let us start with WiFiClientSecure library. ESP32 HTTP...
Configuring the PWM channel in ESP32 is similar to theanalogWrite()function in Arduino programming. But here we will be using a dedicated set ofledcSetup()functions for configuring PWM in ESP32. Pretty much everything needed for a PWM signal likechannel,resolutionandfrequencycan be easily configu...
Using Arduino IDEIf your development needs are less sophisticated and do not merit the power of the Eclipse IDE, the Arduino IDE might be sufficient. This would be appropriate if you want to use the ARTIK to emulate an Arduino with its simple initialization and loop application paradigm....
The TX pin of the GPS shield transmits raw NMEA sentences to the RX1 pin of the Arduino hardware. The algorithm decodes the data and sends the data to the serial terminal on your computer. 5. Open the serial terminal on your computer (for example, Arduino IDE serial monitor). Wh...
Wrong baud rate or failed to upload code: if you don’t see anything in your Arduino IDE Serial Monitor double-check that you’ve selected the right baud rate, COM port or that you’ve uploaded the code successfully.While building our projects, we’ve experienced similar issues with the DH...
Serial.println (" device(s)."); } // end of setup void loop() {} Load this sketch into your Arduino then open your serial monitor. You’ll see the I2C address of your I2C LCD display adapter. You can then make note of this address and use it in the sketches we’ll be looking...
Slave Address: 1 (match withnode.begin(1, ...)). Register Address: 0x0000 (adjust in code if needed). Test with aModbus simulator(e.g.,QModMaster) if you don’t have hardware. Result With Video: After uploading the Arduino Sketch to ESP32 Board, open the Serial Monitor Window and...

The following code will test the speed sensors and display the motor rotation speed in RPM on the Arduino serial monitor. You can watch the experiment in the YouTube video associated with this article or give it a try yourself. In the video I just hooked the motors directly to a 6-volt...
It is possible to use iLLD libraries and Arduino's libraries at the same time in the Arduino's IDE. I'll leave you an example below (NOT OFFICIAL CODE) : #include "IfxPort.h" #define LED &MODULE_P10,2 /* DAM RAM uninitialised data */StartOfUninitia...
