๐ฅ The objective is to control the temperature of a fan using an operational amplifier and a transistor.
๐ ๏ธ Various components, such as resistors and diodes, are used to build the circuit.
๐ The circuit is connected using a protoboard and wires, and the power supply is properly configured.
๐ The video discusses the use of a temperature sensor (LM35) and an operational amplifier in a fan control system.
โก The LM35 sensor is connected to the 12-volt power supply and its signal is sent to the non-inverting input of the operational amplifier.
๐ง The amplification of the signal is determined by the two resistors (20kฮฉ and 100kฮฉ) in the configuration, and the overall gain is calculated using the formula A = 1 + (RF / R1).
๐ง The video shows how to build a temperature-controlled fan using resistors, transistors, and a sensor.
๐ก๏ธ By adjusting the resistors, the gain of the amplifier can be set to control the temperature at which the fan turns on.
๐ The temperature sensor sends a signal to the amplifier, which then activates the fan to regulate the temperature.
๐ The circuit uses a temperature sensor and operates with 12 volts.
๐ถ The temperature signal is amplified and sent to the input of the operational amplifier.
โก The circuit includes resistors and a motor for controlling the fan speed.
๐ The video discusses the construction of a temperature-controlled fan using an operational amplifier.
๐ก The necessary components, including resistors and a diode LED, are explained and connected in the circuit.
๐ The function of the transistor and the importance of polarity in protecting the circuit are demonstrated.
๐ The video demonstrates the construction of a temperature-controlled fan circuit.
๐บ The circuit includes resistors that sum up to a total resistance of 20k, providing a gain of 5 for the amplifier.
๐จ When the temperature rises, the fan is activated to cool the environment.
๐ก๏ธ The video demonstrates how to create a temperature-controlled fan.
๐ By connecting a temperature sensor and a fan to a microcontroller, the fan turns on when the temperature exceeds a certain threshold.
๐ก The fan is controlled using an easy-to-understand Arduino code, making it a beginner-friendly project.
