Project Specification

Overview

Simple 9V battery-powered LED blinker using a through-hole NE555 timer in astable mode.

Architecture

Diagram

Functional Blocks

Power input: BT1 9V battery connector and SW1 SPST switch.
Timing: U1 NE555P with R1 = 47kΩ, R2 = 47kΩ, and C1 = 10µF.
Output: U1 OUT drives R3 = 680Ω and D1 red LED to GND.
Stability: C2 = 10nF on CONT and C3 = 100nF from VCC to GND.

Key Calculations

Astable period: T = 0.693 × (47kΩ + 2 × 47kΩ) × 10µF ≈ 0.977s.
Blink frequency: approximately 1.02Hz.
LED current: (9V - 2V) / 680Ω ≈ 10.3mA.

Assembly Requirements

All selected/configured parts are through-hole or hand-solderable for a simple prototype PCB.
