Hi buddies!! In our previous class, we built a 7-segment display counter using an 8051 microcontroller. In this tutorial, let’s see how to display the same counter output on an LCD display. 📺 How Does an LCD Work? An LCD consists of three major parts: Backlight – A small LED that provides light behind the display. Liquid Crystals – These crystals align when voltage is applied, allowing them to either block or twist light. Polarizer […]
Hi buddies! In this tutorial, let’s learn how to create a simple 0–9 counter using a 7-segment display and an 8051 microcontroller. If you’re just getting started with embedded systems, this is a perfect project to understand digital output and counters! 🧠 What is a 7-Segment Display? A 7-segment display contains 7 individual LEDs arranged to form numbers from 0 to 9. These LEDs are named from a to g, and there’s sometimes an additional […]
