Instead of datasheets360 using up a dozen- - so of your microcontroller' s pins to control the LEDs all you need is one. Similar to datasheets360 the previous example LinkIt 7697 connects to the input pins of 74HC595 with orange wires the output pins of segmenti 74HC595 are with blue wires. Moreover, four control pins ( yellow wires) are needed from LinkIt 7697 to turn on / off each digit in the module. Driving four seven- segment display with one 74HC595. This application note shows a typical application configuration for driving sixteen mono- color 7- segment LEDs using the MAX6954. We use seven segment display that will display number from 0- 9 in a single datasheets360 segment. The MAX6954 is a versatile segmenti display driver capable of controlling a mix of discrete, 7- segment, , 14- segment segmenti 16- segment LED displays datasheets360 through a serial interface. The supreme light intensity allows applications under direct sunlight or segmenti “ black segmenti front” designs by using tinted datasheets360 filter glass in front of the display. The Serial 7- Segment Display is an easy- to- use 4- digit display that is controlled using a serial interface.
Questo modulo e' composto da 4 display a 7 segmenti pilotati dal driver TM1637 ( qui il datasheet) monato sul retro del modulo Il chip TM1637 ha anche la capacita' di leggere gli scan code di un tastierino 4x4, ma non viene trattato in questo post. A 5VDC Arduino Uno or Nano with the ATMega328 microprocessor can safely power this project, driving the 74HC595 Shift Register and Toplite 5161BS 7 Segment LED Display used to develop this tutorial. Any other Single Digit 7 Segment LED Display should be safe to use as long as total current does not exceed 200mA. Display 2 contains digits 4 and 5, and Displa y 3 contains digits 6, 7, and 8.

Notice that although the 8 digits have been arranged in 3 groups, the digit numbers are still consecutive. The severe downside is that it takes longer to display information and brightness is reduced because the program needs to cycle through all the 7 segments + decimal or each LED first before moving to the next digit or row.
