Ultrasonic distance level meter without arduino microcontroller

Visitor counter without microcontroller course, in this course you’ll learn how to design and build a simple visitor counting system using analog components without the need for programming or microcontrollers. This course will cover the fundamental concepts of counting circuits and guide you through using sensors and basic integrated circuits, such as the IC 4026 and a 7-segment display, to create a reliable counter. You’ll learn how sensors like infrared (IR) or light sensors detect when someone passes by, triggering the counting mechanism to increment the display. We’ll dive into circuit design basics, including how to wire the IC 4026 to count each visitor and display the number on a 7-segment LED. The course will also cover powering the circuit, adjusting sensor sensitivity, and handling common issues such as false counts. By the end of the course, you’ll have built a fully functioning visitor counter ideal for small spaces like shops, exhibitions, or offices, all without needing a microcontroller. This hands-on course is perfect for beginners in electronics, offering a practical approach to real-world circuit design and sensor integration.
