Another illustration that demonstrate how to use the NRF24L01 2.4GHz wireless radio scanner to display the interference signals in WLAN. As you can see the diagram below its use only one common NRF24L01 module which is connected to Microcontroller SPI
Wiring the HC11 & HC12 434/433MHz Transceiver
In this tutorial we will going to wire the HC11 / HC12 UART module a new generation multi-channel embedded wireless transmission module. This module is works on 433 ~ 473 MHz frequency band, you can also set this module works
Bluetooth Home Automation with Arduino and Android
In this illustration we will going to wire the HC-04,HC-05 or HC-06 module using serial communication with our Arduino board and 4 channel relay, we will going to control the relay on the Android smart phone or tablet via Bluetooth
