How to Use TM1637 and Four Seven Segment Display Module

How to Use TM1637 and Four Seven Segment Display Module

A seven segment display has one pin for each of its seven segments. This means if directly interfaced with a microcontroller, you will need at least seven pins. Fortunately, there is a way to use four seven segment displays and using only four pins from your Arduino.

The main aim of this project is to understand that how Seven Segment Interfacing with Arduino is explained with seven segment multiplexing & distance measurement using ultrasonic sensors.

Towards DIY Flip Digit Clocks

Seven segment displays and Nixies are one thing, but the king of all antique display technologies must be electromechanical flip dots. These displays, usually found in train stations or rarely on old bus lines, are an array of physical disks, black on one side, light on the other, that ‘flip’ back and forth with the help of an electromagnet. They’re expensive and impressive, driving them is a pain, but oh man do they look awesome. While flip dot displays can be bought new if you know where to look, [sjm4306] had the idea to build his own out of inexpensive …read more http://pje.fyi/PNKX86

Progress!

Wanted to upload a movie to show how the Arduino Countdown Clock just wakes up as soon as you open the cardboard box and starts the stressful countdown to zero, but Tumblr would have none of it tonight. We are not done adding all the required stressful sounds, blinking lights, etc… but with Tully’s help tonight and a fair amount of trial an error (error being the keyword here), we managed to reach roughly an 85% completion level. This “Movie Prop” needs to be completed by Nov. 8th so time is running out… LITERALLY!

Here is the flowchart of my desired functionality. I am currently having trouble integrating all the functionality as the Seven_Segment library (from Tully/Devon) supports Counting Down & producing speaker tones while the awesome Doomsday library (from Devon) supports the Photoresistor, produces tones, can blink the seven segments LCDs & strobe/chase the dots on top but I have not been able to make it count down, which is the whole purpose for the clock...

Imagine as soon as you open a closed cardboard box, the photoresistor triggers and the countdown starts with no ability to stop it...

Assembled the brown-paper battery holders and found a suitable transparent box to hold the countdown clock.

I finally got to talk with Devon, the creator of the Doomsday library the clock uses and confirmed that he is an amazing software developer. Also found that he is a real nice guy and he even speaks French!

I am hoping to record and post a movie soon of the full cycle of countdown to display all the special effects the device will have.
