![]() ![]() ![]() The segments are conventionally notated from a to g in the manner shown in the diagram, and it is possible to make them display any number (numeral) from 0 to 9 or alphabetic character from A to F (in a mixture of upper and lower case letters) by activating these segments in various combinations, as shown in the truth table in Figure 2.įIGURE 2. Standard form and notations of a seven-segment display. The best known type of alphanumeric indicator is the seven-segment display, which comprises seven independently-accessible photoelectric segments (such as LEDs or LCDs, or gas-discharge or fluorescent elements, etc.) arranged in the form shown in Figure 1.įIGURE 1. Digital watches, pocket calculators, and digital multimeters and frequency meters are all examples of devices that use such displays. The module is an excellent display for lots of Arduino projects, it is cheap, clear to read and has an enclosure.» Skip to the Extras SEVEN-SEGMENT DISPLAYSĪ very common requirement in modern electronics is that of displaying alphanumeric characters. ShiftOut(dataPin, clockPin, LSBFIRST, LED_SEG_TAB) The Green PCB displays the digits in reverse order 4, 3, 2, 1 and the red PCB displays as digit 1, 2, 3, 4 – They are the same product, though with one slight difference, the order the digits display. After contacting the company I found out that there are 2 versions, one is the Green PCB (shown in product image), and the other is a Red PCB (the one I received). I initially gave this product a 1 star rating because it didn’t look like the one in the image nor did it work the same. Needs 300mA to display 8888, because the high brightness.If you don’t need enclosure, there are four screw holes, easy to install too.VCC, GND, SDI – DATA in, SCK|CLK – clock, RCK|LCK latch lock.four displays, can connect one by one, and only connect the three wires of the first display to MCU is enough. Simple interface: +5V, -5V, data, data shift CLK, latch LCK, only need 3 wires to MCU, save resources.Static driven, when the number is not changing, MCU don’t need to refresh it, save MCU resources.All the segment display are current limited. ![]() All these four seven segment display controls by 4 pieces 74HC595 ICs where are on the back PCB board.The mounting hole dimension should 72*39 mm, and you need leave two extra cutout place for the “ear” on the side of the panel. Standard 5135 enclosure, nice look, easy to install on devices.See the pictures about how it looks like. There is four 7 segment display inside of this module, with a PCB control back board.
