433MHz RF Transmitter and Receiver Modules with Arduino.

433MHz RF Transmitter and Receiver modules are cheap wireless modules providing one-way communication capabilities using Amplitude Shift Keying.
In this tutorial I demonstrate how these modules work with Arduino to wirelessly send temperature and humidity readings from a DHT11 sensor.

I'm curious, about the Tx and Rx pins.
😁 Howcome no one is using that? 🤔 What's it's purpose for?

The schematic diagram of the IC pins, maybe different.
