Explanation of 8-Channel IR Remote Switch

Arduino Nano

Arduino Nano is a compact and easy-to-use development board based on the ATmega328P microcontroller. It is roughly the size of a credit card, making it one of the smallest and most versatile Arduino boards available. Its small size makes it perfect for projects where space is limited, such as wearables, drones, and IoT devices.

TSOP1838 IR Sensor:

The TSOP1838 is an infrared (IR) sensor that is widely used in remote control applications. It is a three-pin device that receives IR signals from a remote control and converts them into electrical signals. It operates at a frequency of 38 kHz and has a range of up to 10 meters. The TSOP1838 is compatible with a variety of remote control protocols, making it a popular choice for DIY projects.

ULN2803 IC:

The ULN2803 is an eight-channel Darlington transistor array that is commonly used in driving high-current loads such as relays, solenoids, and stepper motors. It contains eight NPN Darlington pairs that can handle up to 500 mA per channel and has a voltage rating of up to 50V. The ULN2803 is ideal for use with microcontrollers such as Arduino Nano, as it can be directly controlled by the digital outputs of the microcontroller.
