Are there conventions to indicate a new item in a list? It was a timer/stopwatch. Note: You should connect digital output pins of Arduino with LED segments pins of a 7-segment display using a 220-ohm resistor. Then the code which I presume you found will have to multiplex the display. You have no current limit resistors? Sometimes the simplest solution is the best solution, thanks Majenko! We have a similar guide with ESP8266 NodeMCU: Now upload this code to Arduino board and observe the output. It only takes a minute to sign up. Hence, unlike direct interfacing method, only four pins of Arduino are used. If your display lacks the extra dots then it may not have the LEDs on pin 11, and pin 12-13 may be moved down one, so you have 4 commons on 9, 10, 11 and 12 with no pin 13. Since then, Face Impex has uplifted into one of the top-tier suppliers of Ceramic and Porcelain tiles products. The best answers are voted up and rise to the top, Not the answer you're looking for? Do you have some sort of guide? If it is there is a simple library to include and a single statement to display a decimal number. Powered by Discourse, best viewed with JavaScript enabled. It is not a practical solution to use 8 digital output pins just for a single display.Therefore, we generally use a separate IC to minimize the use of digital output pins. Experimentally I found out how it works, even though I don't understand it, but anyways every segment is lit by a combination of HIGH and LOW of certain two pins, the combinations are below: So I tried to make it work, but encountered the following problem (as you can see in the first picture): if, for example, I want to activate the segment that requires pin 5 high and pin 6 low, it also activates the other segments that require 5 to high, because apparently if a digital output is not high, it's automatically pulled to ground, and that's a problem. As you see the pinout of a common anode 7-segment display by facing a dot point towards the upper side, pins 1-5 are on the upper side, and pins 10-6 are the lower side of the module.
