The history of embedded hardware development is closely tied to the evolution of microelectronics and computer science. It's a journey from bulky, specialized systems to the sophisticated, ubiquitous devices we see today.

Early Days (1960s-1970s):

• Apollo Guidance Computer (AGC): One of the earliest examples of an embedded system, the AGC was used in the Apollo missions to the moon. It was a complex system for its time, using integrated circuits to control the spacecraft.
• Microprocessors: The invention of the microprocessor in the early 1970s revolutionized embedded systems. The Intel 4004, introduced in 1971, was one of the first commercially available microprocessors, paving the way for smaller, more powerful embedded systems.

Growth and Expansion (1980s-1990s):

• Consumer Electronics: Embedded systems began to appear in a wide range of consumer electronics, such as washing machines, microwave ovens, and VCRs. These systems used microcontrollers to control the device's functions.
