Touch Sensor Circuit Without IC | Easy Project #experiment #shorts #arduino #circuit #bc547

In this video, I show how to make a Touch Sensor LED using a BC547 transistor — no switch required!

This simple electronics project allows an LED to turn ON just by touching two points. It works by using the small current from your body to activate the transistor.

What you will learn:

- How a touch sensor circuit works
- BC547 transistor pinout (Emitter, Base, Collector)
- Step-by-step circuit connections
- Practical demonstration

Components used:

- BC547 Transistor
- Resistors (10k, 1M)
- LED
- Capacitor (optional)
- 5V Power Supply

This is a great beginner-friendly DIY electronics project for students and hobbyists.
