List of components:
| Name | Value | Description |
|---|---|---|
| Raspberry Pi 3B | / |
Processor: ARM Cortex-A53 64-bit quad-core processor. Clock frequency: 1.2 GHz. Memory: 1 GB LPDDR2 SDRAM. Storage: microSD card slot for OS and data storage. Ports: 4 x USB 2.0 ports, standard HDMI, 10/100 Mbps Ethernet, 3.5mm audio output. Wireless: Built-in Wi-Fi 802.11n and Bluetooth 4.2. GPIO: 40-pin header, compatible with previous models for sensor and device connections. OS Support: Supports Raspberry Pi OS (formerly Raspbian) and other Linux distros like Ubuntu Mate, OSMC, LibreELEC, etc. |
| Red LED | λ = 635nm | A red LED that emits light when current flows through it. Voltage: Typically between 1.8V and 2.2V. Current: Typically 20 mA. Use: Indicates errors or prohibited states. |
| Yellow LED | λ = 590nm |
Voltage: Typically between 2.0V and 2.5V. Current: Typically 20 mA. Use: Commonly used in traffic lights or as a warning indicator. |
| Green LED | λ = 520nm |
Voltage: Typically between 2.0V and 3.5V. Current: Typically 20 mA. Use: Often used in various devices as a status indication (e.g., successful operation). |
| ADC | / | ADC is a device that converts an analog signal to a digital signal. Resolution: Expressed in bits (e.g., 8-bit, 10-bit, 12-bit). Max Frequency: Indicates the speed of conversion. Use: Used in projects requiring voltage, temperature, or humidity measurement. |
| ADC12 Click | / | ADC12 Click is an add-on board for Raspberry Pi or MikroBUS platforms containing a 12-bit Analog-to-Digital Converter. Resolution: 12-bit for precise measurement. Interface: Communicates via I2C or SPI. Use: Commonly used to measure temperature, voltage, or other analog signals. |
| Buzzer | I = ≥85dB | Buzzer is a device that produces sound when current passes through it. Voltage: Typically operates at 5V. Tone: Can produce various frequencies depending on operation mode (active or passive); Here: Active. Usage: Used in alarms, signaling, and notification systems. |
| Passive Components | R = ~270Ω | Resistors used for current limiting, in a pull-down configuration. |
| Wires | / | Conductive components that enable proper electrical connections within the system. |
