IR Remote Control for Servo Motor with Arduino
Code Explanation
This code controls a servo motor using an IR remote and an Arduino. It includes functions to decode IR signals, validate remote codes, and perform actions based on the received key presses.
IR Remote Codes
The code defines arrays to store IR codes for both white and black remotes, along with their corresponding key names. These codes are specific to the Robojax IR remote but can be modified for other remotes.
White Remote Codes (Non-PCB Version)
unsigned int whiteRemote[] = { ... };

Process Management
A process is an instance of a program in execution. The operating system (OS) provides essential resources and abstractions for each process, including:
- Logical Flows of Control:
- Single-threaded programs have one flow of control.
- Multi-threaded programs have multiple flows of control.
- Private, Protected Address Space: Each process has its own isolated memory space for security and stability.
- Abstracted Resources: The OS provides a layer of

Phenolic Resins
Phenolic resins are formed by combining phenol (carbolic acid) with formaldehyde. They are known for their electrical insulation properties and are used in power supplies, handles, switches, plugs, housings, and various boxes. Trade names include Bakelite, Durito, and Resiform.
Urea Resins
Urea resins are synthetic materials made from urea and formaldehyde. They are commonly used in electrical equipment (switches, plugs), insulation boards, and kitchen items. Trade names include Pollopas,
