Also note that as size and colour differs the amount of current consumed by the display will also differ. If you are planning to make your project look out of the box, then other colour display can also be used. The default and most commonly used / available one is the 14.20mm with Red colour display as show in the above animation. There many different types of size and colours to select from. We also have an option to show a decimal point using the DP pin.Īs discussed in the Features there are many options to choose for a 7-segment display. This way we can power more than one segment at a time to represent the numeric number 0-9 and also few Alphabets as shown on the graphic image below. So to make an LED of a particular segment glow we just have to power common pin along with the segment pin. These entire 8 segment LEDs have one end of their pins pulled out of the module as shown above and the other ends are connected together and pulled out as the Common pin. These 8 LEDs are separated into each segments which can be named as a,b,c,d,e,f,g,DP as shown in the picture above.
This display has nothing more than 8 LED inside it. The seven segments displays are the oldest yet one of the efficient types of display used in embedded applications. More details can be found at the datasheet given at the end of this pageĭot Matrix LED Display, 16×2 LCD Displays, OLED Display, TFT LCD Screen Display Note: The above current rating is for 14.20mm Red colour 7-segment display. Better, brighter and larger display than conventional LCD displays.Available colours: White, Blue, Red, Yellow and Green (Res is commonly used).
Available in many different sizes like 9.14mm,14.20mm,20.40mm,38.10mm,57.0mm and 100mm (Commonly used/available size is 14.20mm).Available in two modes Common Cathode (CC) and Common Anode (CA).If your display is not at 9600bps, you can do a software or hardware reset.Controls the left bottom LED of the 7-segment displayĬontrols the bottom most LED of the 7-segment displayĬonnected to Ground/Vcc based on type of displayĬontrols the right bottom LED of the 7-segment displayĬontrols the decimal point LED of the 7-segment displayĬontrols the top right LED of the 7-segment displayĬontrols the top most LED of the 7-segment displayĬontrols the top left LED of the 7-segment displayĬontrols the middle LED of the 7-segment display
