7-सेगमेंट डिस्प्ले (एक अंक, 10-पिन) पिनआउट

पिन

Top row, left to right (decimal point at the bottom right): g, f, COM, a, b
Bottom row, left to right: e, d, COM, c, dp
a, b, c, d, e, f, g — the seven segments, lettered clockwise from the top (g is the middle bar); dp — decimal point
COM — both COM pins are the same net: common cathode (tie to GND) or common anode (tie to +V); check the part number before wiring

Digit height	0.56 in (14.2 mm)
Configuration	Common cathode (5161AS) or common anode (5161BS)
Segments	7 + decimal point
पिन	10 (2 × COM, same net)
Forward voltage	≈ 2 V per segment (red)
Forward current	≈ 10–20 mA per segment
Series resistor	220–330 Ω per segment at 5 V
Driving	One GPIO per segment, or a driver IC (MAX7219, TM1637, 74HC595)

Each segment needs its own current-limiting resistor (~220–330Ω at 5V).
This is the 0.56" single-digit layout (5161AS common cathode / 5161BS common anode); other sizes keep the same pin order.
