Binary and Hexadecimal Number Counter

What is Binary and Hexadecimal? Binary and hexadecimal are two numeral systems used in computing and digital electronics. Here's a brief explanation of them both:Binary:Binary is a base-2 numeral system, which means it uses only two digits: 0 and 1.Each digit in a binary number represents a power of 2, with the rightmost digit representing 2^0 (1), the next digit to the left representing 2^1 (2), the next 2^2 (4), and so on.Binary is the fundamental language of computers. Computers…

Theremin: Build Your own Arduino based Theremin

What is a Theremin? The theremin is an electronic musical instrument that is unique in that it is played without physical contact. It was invented by Léon Theremin, a Russian inventor and musician, in the early 1920s. The theremin's unique method of sound production relies on the interaction of electromagnetic fields with the player's hands, which control pitch and volume by moving their hands closer to or farther from two antennae on the instrument. Its eerie and ethereal sound has…
