- Countimer
This is simple timer and counter Arduino library. Offers three work modes: Count-up timer with call specified method when count is complete. Count-down timer with call specified method when count is complete. Calling any method at a specified time interval. It allows you to start/pause, stop or restart timer.

A single shot delay is one that only runs once and then stops. It is the most direct replacement for the Arduino delay()method. You start the delay and then when it is finished you do something. BasicSingleShotDelay is the plain code and SingleShotMillisDelay uses the millisDelay library.
This sketch is available in BasicSingleShotDelay.ino In the code above the loop() continues to run without being stuck waiting for the delay to expire. During each pass of the loop(), the difference between the current millis() and the delayStart time is compared to the DELAY_TIME. When the timer exceeds the value of the interval the desired action...
Here is the BasicSingleShotDelay sketch re-written using the millisDelay library. This sketch is available in SingleShotMillisDelay.ino Here is the millisDelay version where the code above has be wrapped in class methods of the millisDelay class.
These are simple examples of a repeating delay/timer. BasicRepeatingDelay is the plain code and RepeatingMillisDelay uses the millisDelay library.
This sketch is available in BasicRepeatingDelay.ino The reason for using delayStart += DELAY_TIME; to reset the delay to run again, is it allows for the possibility that the millis()-delayStart may be > DELAY_TIME because the millis() has just incremented or due to some other code in the loop()that slows it down. For example a long print statement....

- Gather the Components. Arduino board (e.g., Arduino Nano) TM1637 display module. Jumper wires. Breadboard.
- Connect the Components. Connect the CLK pin of the TM1637 display module to any digital pin on the Arduino (e.g., pin 2). Connect the DIO pin of the TM1637 display module to another digital pin on the Arduino (e.g., pin 3).
- Install the TM1637Display Library. Open the Arduino IDE software. Go to "Sketch" -> "Include Library" -> "Manage Libraries". In the Library Manager, search for "TM1637Display".
- Open a New Sketch. Open a new Arduino sketch in the IDE.

Arduino Countdown Timer: The Arduino Countdown Timer is a fun weekend project for beginners who wants to move on to something slightly more advanced. The timer controls two 7-segment displays which count down from 99 to 0, and can be stopped and started using a button.

Countdown Library. Arduino Library implements a simple counter. Apart from using a simple counter, such as a lap counter or an encoder, the main interest of the library is to use the Callback function to release part of the code to the program main stream. Author: Luis Llamas.
