3-Digit 7-Segment Common Anode LED Display – Red Color

A 3-digit 7-segment common anode led display is a type of digital display that uses 7 LEDs to display a single digit, plus an eighth LED for the decimal point. The common anode means that all the anode connections of the LEDs are connected together, and the individual segments are illuminated by applying a ground signal to the cathode of the particular segment.

The display is typically driven by a microcontroller, which sends signals to the appropriate pins to light up the desired segments. For example, to display the number “123”, the microcontroller would send a signal to pins 1, 2, 3, 4, 5, 9, 10, and 11.

The display can also use to display other characters, such as letters, symbols, and punctuation marks. The specific characters that can display are determined by the character set that used.

The input voltage for a 3 digit 7 segment common anode display is typically 3.3V or 5V. The specific voltage required will depend on the display you are using.

The forward voltage of a LED is the voltage that is required to turn the LED on. The forward voltage of a 7 segment common anode display LED is typically around 1.8V. This means that the input voltage of the display must be at least 1.8V higher than the forward voltage of the LEDs.

The current draw of a 7 segment common anode display LED is typically around 20mA. This means that the input current of the display must be at least 20mA.

It is important to note that the input voltage and current of the display must be within the specified limits, otherwise the display may damage.

Features : –

The display features one decimal point per digit, and individually controllable apostrophe and colon points. The 3 Digit 7 Segment have a forward voltage of 3VDC and a max forward current of 20mA. This is the way the display works. It’s multiplexed, so you select the digit by setting its pin (we’ll get into pins later) HIGH, and you select the segment by setting its pin LOW.

here are some of the benefits of using a 3 digit 7 segment common anode display:

• Small size: 3 digit 7 segment common anode displays are relatively small, making them a good choice for applications where space is limited.
• Bright and easy-to-read display: 7 segment displays are typically very bright and easy to read, even in low light conditions.
