🌡️Make a Temperature Meter Using LEDs and NTC #Shorts

In this project, I built a temperature meter using LM3915 IC and an NTC 10K thermistor. The circuit converts temperature changes into a clear LED bar graph display, where green LEDs show low temperature, yellow shows medium, and red LEDs indicate high temperature.

As the temperature increases, the resistance of the NTC decreases, causing more LEDs to turn ON. This makes it easy to visually monitor temperature without using any microcontroller or digital display.

This analog temperature meter is simple, low-cost, and ideal for learning electronics. It can be used for heat monitoring, basic thermal indication, or educational projects.

⚠️ This is an indicator, not a precision thermometer, but it works great for understanding temperature variation visually.
