Certainly! Let's break down the project step-by-step:

Project Overview

The project is a simple LED circuit that involves a resistor, an LED, and a voltage source.

Components

Resistor (R1)
- Designator: R1
- Manufacturer Part Number (MPN): CFR-12JB-52-330R
- Value: 330 Ohms
- Manufacturer: Yageo
- Pins:
  - 1 (P1)
  - 2 (P2)
LED (LED1)
- Designator: LED1
- Manufacturer Part Number (MPN): 598-8070-107F
- Forward Voltage: 2V
- Current: 20mA
- Manufacturer: Dialight
- Pins:
  - Anode (A)
  - Cathode (K)
Voltage Source (V1)
- Designator: V1
- Voltage: 5V
- Pins:
  - Anode (ANODE)
  - Cathode (CATHODE)

Net Connections

Net 1 connects:
- $\text{R1:P2}$ to $\text{LED1:A}$
GND connects:
- $\text{LED1:K}$ to $\text{V1:ANODE}$
Net 3 connects:
- $\text{R1:P1}$ to $\text{V1:CATHODE}$

Circuit Description

The 5V voltage source $\text{V1}$ provides power to the circuit.
The resistor $\text{R1}$ limits the current flowing through the LED to protect it from damage.
The LED $\text{LED1}$ emits light when current flows through it.

Calculations

To ensure the LED operates within its specified current rating (20mA):

The total voltage drop across the resistor $\text{R1}$ and LED $\text{LED1}$ is 3V (5V - 2V).
Using Ohm's Law: $R = \frac{V}{I} = \frac{3V}{0.02A} = 150 \Omega$

But the resistance value used is 330 Ohms, meaning the actual current will be:

I = \frac{V}{R} = \frac{3V}{330 \Omega} \approx 9.09mA

This is a safe value for the LED.

Summary

This simple circuit lights up an LED when powered with a 5V source, with a current-limiting resistor to protect the LED. The project uses standard components available from various distributors.

Sure! Let's break down the project step-by-step:

Overview

The project consists of a few components: two resistors, an LED, and a power source. These components are arranged in a simple circuit to power the LED.

Components

Resistors:
- R1:
  - Resistance: 330Ω
  - Manufacturer: Yageo
  - Package: Through-hole
- R2:
  - Resistance: 220Ω
  - Manufacturer: Vishay
  - Package: SMD 0402
LED:
- LED1:
  - Manufacturer: Dialight
  - Forward Voltage: 2V
  - Current: 20mA
  - Package: SMD 0603
Power Source:
- V1:
  - Voltage: 5V
Connections:
- GND:
  - Shared ground for the circuit.
- [Net 1](Net 1):
  - Connects several nodes in the circuit.
- [Net 3](Net 3):
  - Connects the power source to the first resistor.

Circuit Explanation

Power Supply:
- The positive terminal (ANODE) of the power supply (V1) is connected to GND (which is actually listed as the ANODE pin name, but is connected to the ground).
- The negative terminal (CATHODE) is connected to [Net 3](Net 3), which includes the first resistor R1.
R1:
- Connect V1:CATHODE to R1:P1.
- R1:P2 connects to [Net 1](Net 1).
LED1:
- The A of the LED (LED1) is connected to [Net 1](Net 1).
- The K is connected to GND.
R2:
- Connect R2:P1 to [Net 1](Net 1).
- Connect R2:P2 to GND.

Summary

When the power supply V1 provides 5V, the currents flow through R1 and R2, setting up a voltage that powers LED1. Resistors R1 and R2 limit the current flowing through the LED to ensure it operates within safe parameters.
