 ## MULTIMETER
 
+A multimeter is a versatile electronic instrument used to measure various electrical quantities in an electrical circuit. It typically combines several measurement functions into one device, including voltage, current, and resistance. Multimeters can also measure other parameters such as capacitance, frequency, temperature, and continuity. They consist of a display screen, selection dial or buttons for choosing the measurement function, and probes or leads for making electrical connections to the circuit under test..

 - We have two wires, one COM and the other VCC.
 - COM is the minus = "GND" the black one.
 - VCC is the plus, which = red one.
 
 ### RESISTANCE
 
+A resistor is an electronic component that restricts the flow of electric current in a circuit. It is typically used to control the amount of current flowing through a circuit or to divide voltage in a circuit. Resistors are designed to have a specific resistance value, measured in ohms (Ω), which determines the extent to which they impede the flow of electricity. They come in various types and sizes, including fixed resistors and variable resistors, and are commonly represented by zigzag symbols in circuit diagrams.

 ### **VOLTAGE**
 
+Voltage, often denoted by the symbol "V" and measured in volts (V), is a fundamental electrical quantity that represents the electric potential difference between two points in an electrical circuit. It is the force or pressure that drives electric charges to move through a conductor, such as a wire or circuit component. In simpler terms, voltage is the amount of electrical potential energy per unit charge available to move electrons from one point to another in a circuit. Higher voltage indicates greater potential for electric current to flow, while lower voltage indicates less potential. Voltage is essential for powering electrical devices and is a key parameter in electrical engineering and electronics.

 ## **CIRCUITS**
 
-Two types of circuits
+A circuit is a closed loop or pathway through which electrical current can flow. It consists of interconnected electrical components, such as wires, resistors, capacitors, inductors, and other devices, that work together to perform a specific function. Circuits can be simple, such as a flashlight circuit with a battery and a light bulb, or complex, such as the circuitry found in computers or electronic devices. Circuits can be classified into various types based on their configuration, such as series circuits, parallel circuits, or a combination of both. They are fundamental to the functioning of electrical and electronic systems, allowing for the control and manipulation of electrical energy to perform useful tasks.
 
 ## DIGITAL SENSOR
 
+A digital sensor is a device that converts physical phenomena, such as light, temperature, pressure, or motion, into digital signals that can be processed by electronic systems. Unlike analog sensors, which output continuous signals proportional to the measured quantity, digital sensors provide discrete, binary data representing specific states or values.

 ## ANALOG (Pressure Sensor)
 
+An analog pressure sensor is a device that measures pressure and outputs an analog signal proportional to the pressure being applied. It typically utilizes a transducer element, such as a piezoelectric material or strain gauge, which deforms in response to pressure changes. This deformation generates an electrical signal, which is then amplified and conditioned to produce an analog output voltage or current. The magnitude of the output signal corresponds to the intensity of the pressure applied to the sensor. Analog pressure sensors are commonly used in various applications, including automotive systems, industrial processes, medical devices, and consumer electronics, where precise pressure measurement is required.
