This document provides a detailed guide to building a relay circuit that uses a Raspberry Pi to control a buzzer. The relay acts as a switch, allowing the Raspberry Pi to turn the buzzer ON and OFF through GPIO pins.

This board measure battery voltage and shows a current battery level. Based on ATTINY13 MCU and compatible with Arduino IDE. J1 is 6-Pin AVR ISP Connector

Generic Connector Single Row 01x06 6 pin 6-pin

WT32-ETH01 carrier refactored for a single 2x10 WT32 header, 12V input terminal, 6-pin Wiegand terminal, and a 12V-to-5V buck stage with level-shifted D0/D1 plus transistor-driven LED and BUZZER outputs, prepared for a simple 2-layer layout.

This project involves a Charge-Coupled Device (CCD) constructed with key components including a TCD1103GFG integrated circuit, SN74AC04PWR IC, several resistors and capacitors, a MMBT5401 transistor, and a 6-pin connector. The design demonstrates a simple CCD application. #referenceDesign #project #sensor #CCD #image
