Is the 51 Microcontroller Still Relevant? A Look at Its Development History as an Outstanding Performer!

On February 15, 1946, the first electronic digital computer ENIAC was unveiled, marking the beginning of the computer era. ENIAC was a vacuum tube computer with a clock frequency of only 100 kHz, but it could perform 5,000 addition operations in one second. Compared to modern computers, ENIAC had many shortcomings, but its emergence opened … Read more
