Introduction: Two LED Fading Circuits|| 555 IC or Transistor
This is a circuit in which the LED fades ON and OFF creating a very soothing effect to see.
Here, I will show you two different ways to make a fading circuit using:
1. 555 Timer IC
2. Transistor
Step 1: Components Required
These are the Components Required for making the circuit:
1. Using 555 Timer IC ()
• 555 Timer IC
• Transistor: BC 547
• Resistors: 330 Ω, 33 K Ω
• Capacitor: 100 μF
• LED
2. Using Transistor ()
• Momentary Switch
• Transistor: BC 547
• Resistors: 330 Ω, 33 K Ω
• Capacitor: 220 μF
• LED
Other Requirements :
• Battery: 9V and battery clip
• Breadboard
• Breadboard Connectors
