Switching of Coil Relay Modules

Image
    Switching of Coil Relay Modules Just Arduino Things | TW TechieTube Try to switch on and off a Coil Relay using Arduino UNO in various methods. Principle: The function of the relay coil is to create a magnetic field that actuates the switch mechanism of the relay. The coil is energized by an electric signal from a power source. When the coil is energized, it attracts the contact and completes the circuit within the relay, turning on or off the load being controlled. The relay coil is an electromagnet that can be operated by a small electric current to control a larger electric current. Components Required: Arduino UNO                                                (1)                         1 Channel 5vDC Relay Module                    (1) ...

Sound Detection using BigSound Sensor

Image
  Sound Detection using BigSound Sensor Just Arduino Things | TW TechieTube Detect a Sound near surroundings and Make an LED Glow system. Principle: Big Sound Sensor is a module that detects sound and its intensity. You can select a point of sound intensity and detect sound when it exceeds a set point. In a loudspeaker, electricity flows into a coil of metal wire wrapped around (or in front of) a permanent magnet. The changing pattern of electricity in the coil creates a magnetic field all around it that pushes against the field the permanent magnet creates. Components Required: Arduino UNO                 (1)                         Big Sound Sensor           (1) Breadboard                     (As per Requirement) Jumper Cables                (A...

Soil Moisture Detection using Arduino

Image
Soil Moisture Detection using  Arduino Just  Arduino Things | TW TechieTube Control your Garden by knowing the temperature of the soil. Principle: The  Soil Moisture Sensor  uses capacitance to measure dielectric permittivity of the surrounding medium. In  soil , dielectric permittivity is a function of the water content. The  sensor  creates a voltage proportional to the dielectric permittivity, and therefore the water content of the  soil. Components Required:- Arduino UNO                                      (1) Soil Moisture Sensor with Interface      (1)  Breadboard                                       (1) Jumper Cables                                ...
