Things used in this project

Hardware components

Esquilo Air

Breadboard (generic)

5161AS 1 digit 7 segment LED display

Resistor 221 ohm

Male/Male Jumper Wires

It is nice to make them color coordinated. I used: 2 black, 1 red, 2 white, 2 blue, 1 orange, 1 green, 1 yellow

Story

This project builds on the typical LED examples because the basics of the 5161AS 1 digit 7 segment LED is basically similar to 8 LEDS except for the difference that they share a common anode or cathode (depending on the type you have). These types of displays are made by several different makers and there are some minor differences in specs and pinout. You may need to find the exact datasheet for the version you have and adjust the wiring diagram to suit.

Here is the pinout for the 5161AS I used for this tutorial:

             AAA 
E     1 --  F   B    -- 10   G 
D     2 --  F   B    -- 9    F 
GND   3 --   GGG     -- 8   GND 
C     4 --  E   C    -- 7    A 
dp    5 --  E   C    -- 6    B 
             DDD  dp

local led = LED_5161AS();

// Turn on all LED segments
led.all_on();

delay(500);

// Turn off all LED segments
led.all_off();

delay(500);

local i;

// Display hex digits 0-f and blink decimal point between
for (i = 0; i < 16; i++) {
    led.digit(i);

    delay(500);

    led.blink_dp();

    delay(500);

    led.blink_dp();
    
    delay(500);
    
    led.blink_dp();
    
    delay(500);
    
    led.blink_dp();
}

delay(500);

led.all_off();
