This project demonstrates creating a hardware-based circuit that mimics a programming [for loop], specifically to blink an LED five times upon button press, using an SR Latch, a 555 Timer, and a 4017 Decade Counter. This approach showcases the integration of classic electronic components to perform a sequence of operations without software, highlighting the enduring relevance and application of these components in modern electronics


When the button is pressed, it activates the SR Latch, maintaining the circuit in an "on" state. The 555 timer, set up as an oscillator, begins emitting regular pulses. These pulses are sent to the 4017 Decade Counter, which advances one count with each pulse. Once the counter reaches the fifth pulse, it sends a signal back to the SR Latch, turning off the sequence, and resets itself to start the count over. This results in the LED blinking five times.
