ESP32 is a series of low cost, low power system on a chip microcontrollers with integrated Wi-Fi & dual-mode Bluetooth. The ESP32 series employs a Tensilica Xtensa LX6 microprocessor in both dual-core and single-core variations. ESP32 is created and developed by Espressif Systems, a Shanghai-based Chinese company, and is manufactured by TSMC using their 40 nm process.^[2] It is a successor to the ESP8266 microcontroller.

Herman Hollerith (February 29, 1860 – November 17, 1929) was an American inventor who developed an electromechanical punched card tabulator to assist in summarizing information and, later, accounting. He was the founder of the Tabulating Machine Company that was amalgamated (via stock acquisition) in 1911 with three other companies to form a fifth company, the Computing-Tabulating-Recording Company later renamed IBM. Hollerith is regarded as one of the seminal figures in the development of data processing.^[2] His invention of the punched card tabulating machine marks the beginning of the era of semiautomatic data processing systems, and his concept dominated that landscape for nearly a century.
