On this mission we’ll see how one can construct a programmable countdown timer within the vary of 1s – 9999s which can be utilized in home or industrial functions in addition to by learners to learn to assemble an digital module and cargo a program.

In the course of the chosen time interval, the system can energy a load by a relay on the board. For repeated timings it’s attainable to memorize the period of the timing, the top of the time interval is signaled acoustically with a “beep” and optically by turning off the LOAD POWER LED.

The wiring diagram is predicated on the Arduino Nano microcontroller which exhibits data on an LED show (such because the one based mostly on the TM1637 chip, used on this case, or the TM1650).
