Registers a function to be called when a slave device receives a transmission from a master. Parameters handler: the function to be called when the slave receives data; this should take a single int parameter (the number of bytes read from the master) and return nothing, e.g.:void myHandl...

The concat() function modifies the original string, and its return value is true if the concatenation is successful and false otherwise. Let’s now dive into a practical example demonstrating the usage of the concat() function: void setup() { String s1 = "Hello"; String s2 = " Arduino"...
Q: Can I use simulators without coding experience? A: Absolutely. Tinkercad’s block-based coding is beginner-friendly, and Wokwi’s examples guide you. Start there before tackling SimulIDE or Proteus. Q: Which simulator is best for IoT projects? A: Wokwi, hands-down, for its ESP32/ESP...
