Recently I went through the Project Idea "IoT-based Air Pollution Monitoring System using Arduino ( https://circuitdigest.com/microcontroller-projects/iot-air-pollution-monitoring-using-arduino ) " published on circuitdigets.com. Here I found some discrepancies w.r.t the article and circuit diagram image. In the article, for connecting Wi-Fi module ESP826 to Arduino, the author has mentioned that the RX pin of the esp8266 to the pin 9 of Arduino, and the TX Pin of ESP8266 to pin 10 of Arduino. However, in the diagram (Image) pin connections are shown as different.
So, KIndly clarify this section. We have already finalized the project.
Thanks in advance.
