C8: Blinker Circuit + PCB Soldering

Aim:
 To build the LED blinker from Lesson 1 using a schematic diagram as your guide.

Requirements:

  • Printed schematic diagram (or drawn on board)

  • Breadboard

  • LED

  • Resistor (470Ω)

  • Capacitor (100µF)

  • 9V battery

  • Jumper wires (same as Lesson 1)

Steps:

  1. Look at the schematic: Identify the symbols for LED, resistor, capacitor, and battery.

  2. Find those components in your kit.

  3. Assemble the circuit on your breadboard by matching connections in the schematic.

  4. Double-check before powering the circuit.

Power it and watch the LED blink!
