7-segment displays comprise 8 LED elements – 7 linear segments that form numerals, plus a circular dot. Numbers 0-9 and some letters (A, C, D, E, F, H, L, O, P, U) are represented using combinations of the 7 lines. The dot creates decimals. Each element connects to a dedicated pin, allowing individual control. Pins […]
