This video contains information about how the high active module works and how the low active module works,
In addition to that the entry must be applied to both,
I also explain there how pull-up resistors and pull-down resistors work to provide voltage input to the relay module,
A Relay is an electronic device that allows you to control an electrical circuit from a low power control signal, such as that produced by an Arduino board. By using a relay with an Arduino, you can control high-power electrical devices, such as light bulbs, motors, or appliances, using digital commands. There are many types of relays available, each with different characteristics and specifications,
Operating principle of a Relay
The operating principle of a relay is based on the use of an electromagnetic coil which is supplied with electric current. When the coil is energized, it generates a magnetic field which attracts a moving contact into contact with one or more other fixed contacts.
When the coil is energized, it pulls the moving contact (or armature) into contact with the stationary contacts (or terminals). Fixed and moving contacts are usually connected to different electrical circuits. When the moving contact comes into contact with the fixed contacts, it allows electrical current to pass from one circuit to another.
The relay coil is usually supplied with direct current or alternating current, and is controlled by a low-power electrical signal, such as direct current or low-amplitude alternating current. When the electrical control signal is applied to the coil, it attracts the armature to pass electrical current from one circuit to another.
The components of a Relay
Vcc Power Pin: This is the pin to which the power supply is connected that powers the relay. It is usually connected to a control circuit or a microcontroller
Input pin IN: This is the pin to which the control signal is connected which activates or deactivates the relay. It is usually connected to a control circuit or a microcontroller.
GND ground pin: This is the pin to which the ground circuit or ground is connected. It is usually connected to a control circuit or a microcontroller.
Contact pins: these are used to connect the electrical circuit that will be activated or deactivated by the relay. There are usually two contact pins, one for the normally open (NO) state and one for the normally closed (NC) state.
Using the Relay with an Arduino board and a lamp
To use a relay with Arduino, you will first need to wire the relay to your Arduino board. Connecting a relay is usually quite simple, as described below:
Connect the power supply (VDC)
Connect the ground (GND) of the relay to the ground of your Arduino
Connect the input pin to a digital pin of the Arduino for example pin 8
Connect the NO and NC pins of the relay module to the light bulb. The NO (Normally Open) pin should be connected to the bulb input and the NC (Normally Closed) pin should be connected to ground.
