What is a countdown timer?

A countdown timer is a digital, analog, or software timer that counts down time to show the remaining time. A countdown timer will stop counting when the count reaches zero.

Stopwatch vs Countdown Timer:

We will compare between stopwatch and countdown timer in this section.

In short, the main difference between the two is:

With the countdown timer, we set a predetermined time to complete a task, but with the stopwatch, we time how long the task took.


(Video) Countdown Timer Circuit Using 7 Segment Display | Working

At numerous points in our lives we use a stopwatch to measure the timing of many events, for example: When playing a board game or at a sporting event or when cooking, to avoid overcooking or undercooking food.

The stopwatch starts counting from zero and increases. The count will be stopped manually when the task is completed. It shows the time it took to complete the task from the beginning. When you reset the stopwatch, it settles to zero.


We also knowingly or unknowingly use the countdown timer in numerous places in our lives, for example: timers on the microwave oven.

In the countdown timer, the amount of time is predetermined to complete a task. For example, we set 2:00 min to heat a food, once the timer counts to zero, it stops its operation.

By now you would have an idea about stopwatch and countdown timer and when to use these two timers.

Design of the proposed circuit:

Now let's dive into the design explanation of the countdown timer.

We will use a 7 segment display to show the counts in combination with the IC 4026 display driver. The proposed circuit will have two digits for the minutes count and two more digits for the seconds count.

The minute digits can be set to a maximum of 99 minutes and the second digits to a maximum of 59 seconds. When the time is set, the timer digits count down.

Two pushbuttons are provided for setting the time, each digit can be set individually. A buzzer is provided to sound an alarm when the counts reach zero.

Now let's look at the pin diagram of IC 4026 driving the 7 segment display.

Countdown Timer Schematic with 7 Segment Display - DIY Electronics Projects (1)

Pinbelegung des IC 4026:

  • Pin #1 is Clock-In, where you input the clock signal.
  • Pin #2 is clock inhibit, when this pin is connected to high, the IC ignores the clock pulses and does not increase the digit. It should be connected to GND to enable count increase.
  • Pin #3 is the display enable, when you set this pin high, the 7-segment display lights up. When this pin is low you can't see the digits, but it counts the digit internally.
  • Pin #4 is not used here.
  • Pin #5 is executed, for every 10 pulses, pin #5 goes high, or we can say this pin is divided by 10 output. We'll use the output of this pin as an input for the clock in of another IC4026.
  • Pin #6, #7, #9, #10, #11, #12, #13 are output for the 7 segment display.
  • Pin #8 is ground supply.
  • Pin #15 is reset, when this pin is connected to high, the IC resets the count to zero, it should be connected to ground during counting.
  • Pin #16 is Vcc (maximum 3 to 15V)

NOTE: The IC 4026 is designed to increment (not decrement) the digits on the 7-segment display.

How to decrement digits on the 7-segment display with IC4026:

We know that IC 4026 always increases the count on the 7-segment display when we apply a clock pulse to the clock pin, but how can we use IC 4026 to decrease digits? Well, this is achieved by using a microcontroller and programming it in a smart way. Let's examine that now.

Usually IC4026 is used in applications where the numbers need to be increased. To increase the digit from "0" to "1" we apply an impulse, to increase from "1" to "2" we apply another impulse, to increase to the next digit we apply another pulse on; This is the same up to the digit "9" and the cycle continues.

Counting down the digit is only possible with the help of a microcontroller, which should be programmed as described below.

(Video) Seven Segment LED Count Down Timer Using Arduino

Arduino controls the rest pin and clock pin of all four IC 4026, to display the digit "9" on the 7-segment display, the Arduino applies nine pulses quickly to the clock pin, to display the digit "8", the Arduino applies one Pulse to reset pin which zeroes the count and quickly applies 8 pulses to the IC. To display the digit "7", the Arduino applies a pulse to the reset pin and 7 pulses fast to the clock pin.

The pulses are applied to the reset pin and the clock pin so fast that we don't see a number transition while it counts backwards from 9 to 0.

By now you understood how we can count backwards with an IC designed primarily for counting up digits.

This completes the circuit diagram and the program code.

How to operate this circuit:

  • Turn on the circuit, the Arduino will perform a display test with all four displays counting from "9" to "0" at the same time. You should look and verify that all segments are properly connected, if not, check and repair the connection(s).
  • After the display test, the rightmost digit (unit digit of the second) lights up and the remaining digits are off. Now press S1 to increase the seconds and press S2 (OK).
  • After pressing S2, the tens digit of the seconds digit lights up and the pause does not appear. Now press S1 to increase the seconds and press S2 (OK).
  • Now the minute unit will light up and press S1 to increase the minutes and press S2 (OK).
  • The tens digit of the minute now lights up. Press S1 to increase and press S2 (OK), now the timer starts.
  • Once the timer has counted all the digits to zero, a beep will sound and the display will flash.

How to make a timer with 555 IC? ›

Use jumper wire to connect pins 4 and 8 to each other (red) and pins 2 and 6 to each other (yellow). Attach the positive lead of a speaker to pin 3 of the 555 and connect the negative lead to ground (pin 1). Low values of RA should be avoided because they prevent the 555 timer from discharging the capacitor C normally.

A Digital Decoder IC, is a device which converts one digital format into another and one of the most commonly used devices for doing this is called the Binary Coded Decimal (BCD) to 7-Segment Display Decoder.

How many bits are needed to display the 7 segment patterns? ›

The seven-segment displays are configured as two 32-bit registers. Each byte of each register directly controls the segments of the corresponding displays, turning them on and off. Thus, it is necessary to provide some decoding to display hexadecimal values on the displays.

What are the two types of seven segment display? ›

There are two different types of driving seven-segment displays:- the common anode type and the common cathode type. In the common anode type all the anodes on the display are tied to a common pin, typically the power source, and the LEDs are controlled via the cathodes with the ground being on and power being off.

How much current can a 555 timer handle? ›

The standard TTL 555 can operate from a supply voltage between 4.5 volts and 18 volts, with its output voltage approximately 2 volts lower than its supply voltage VCC. The 555 can source or sink a maximum output current of 200mA, (but it may get hot at this level), so the circuit variations are unlimited.

Are 555 timers still used? ›

To that end, two types of 555 timers are in use today, both being eight-pin chips. The most common is the rectangular “V” package, which has four pins down each side. The other version, which used to be the most common but has now fallen somewhat from favor, is the circular “T” package.

Do 7-segment displays need resistors? ›

Each individual LED in the 7-segment display needs a resistor between it and the Propeller's I/O pin. When each I/O pin is set to high (outputs 3.3 V), the LED it is connected to lights up. Any resistor value between 100 Ω and 1 kΩ will work for the LED resistor and the lower the resistance, the brighter the segment.

How to make a 7-segment display using Arduino? ›

Connect either of the common pins (seven-segment pin 3 or 8) to the ground. And connect the rest of the pins to D2 to D9 of the Arduino through a current limiting resistor, as per the connection diagram. Just like driving an LED, it is preferable to use these current limiting resistors to increase the display life.

How do you control multiple 7-segment displays? ›

To control the segments on a single-digit 7-seg display, you need at least seven GPIOs. And in order to control multiple digits at once, we need one additional GPIO for each scan pin. This can really add up, so we can use a shift register to increase the number of output pins available to us.
