Learn how to use the Arduino nRF24L01 module for wireless communication. This beginner-friendly guide covers wiring, code, and troubleshooting to kickstart your Arduino RF projects.

In it, he shows an example of using all three ESP32 UARTs from an Arduino program. He calls the third port “secret” although that’s really a misnomer.

STEP 4 Set the board type and the serial port in the Arduino Programmer. STEP 5 Test the microcontroller by using one of the preloaded programs, called sketches, in the Arduino Programmer.

To do so, the Arduino was set up to monitor the BUSY line on the printer’s parallel port, setting the CTS line active whenever the busy line was inactive.

An Arduino Uno (CH340G clone) reads temperature and humidity from a DHT11 sensor and computes 10+ environmental metrics (heat index, dew point, enthalpy, humidex, vapor pressures, etc.), outputting ...
