Arduino infrared remote controller design purpose

Arduino infrared remote controller is designed for instruction coding system. The infrared remote controller is generally composed of command key, command coding system, modulation circuit, driving circuit, infrared emission circuit lamp and so on. When the command key is pressed, the command encoding circuit generates the required command encoding. Infrared remote control is a wireless non-contact control technology, which has obvious advantages such as strong anti-interference ability, reliable information transmission, low power consumption, low cost and easy implementation. It is widely used by many electronic devices, especially household appliances, and is increasingly used in computers and mobile phone systems.
