The wireless TX (Transmitter) RX (Receiver) pair operates at 315 MHz radio frequency, they can easily plug and test into a solder less breadboard and work well with microcontroller to create a simply wireless radio data link. This 315 MHz
Working with Reed Switch and Magnetic Field
The reed switch is an electrical switch which is operated by an applied with a magnetic field. When the magnet close the Reed Switch it will activate as HIGH, The Reed Switch was invented at Bell Telephone Laboratories in 1936.
RFID RC522 Gate Access Control with Arduino
In this illustration we will going to wire the RFID (Radio Frequency Identification) Module RC522 in this module it uses a radio signals and a Radio Label Tags for reading and writing data. How RFID works please refer to this
Wiring HC-SR04 Ultrasonic on Reverse Parking Sensor
In this illustration we will going to wire the Ultrasonic HC-SR04 with our Arduino board, to build a parking sensor which emits a beep as the sensor approaches or detect an obstacle. The closer the obstacle, the greater the frequency
