Use this template if you're planning to get your 1 to 2-layer board manufactured in JLCPCB. It has the via min/max and trace width constraints already baked as global rules. #project-template #template #manufacturer-design-rules
This project was intended for the spirit of Halloween, This circuit functions are meant to detect the movement of an object holding candies. If the sensor detect that anyone moves the object, it will send the data from the sensor to the microcontroller. Lastly, once the microcontroller receives the data, it will send it to the buzzer to output a buzz that will stimulate a shock.
makes a circuit which has transistors, diodes, relays, IC Timer, LED, which first turns on a green LED lit from 0 to 35 degrees Celsius then turns off and turns on a yellow LED from 35 degrees Celsius to 50 degrees Celsius then turns off the yellow and turns on the red at 50 degrees or more which in turn will turn on an oscillator circuit with IC555 and a Buzzer. In addition it should turn on an exhaust fan at 110 VAC.

Mini Paper USV PCB Upgrade v1.0 schematic twin using an ELEGOO MEGA 2560, L293D H-bridge, HC-SR04 ultrasonic sensor, SG90 servo header, LED indicators, buzzer, and dual 9V parallel battery input.
This module involves the design of a keypad lock system. It utilizes an ATMEGA328P microcontroller, buzzers, LEDs for indicator functions and a 4x3 matrix keypad. An in-circuit serial programming (ISP) header is also present for programming the microcontroller. #template #lock #keypad #reusable #module #simple-embedded #microchip #arduino #atmega328 #TPS613222A #ISP #buzzer #sublayout
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 is a schematic of an IR (infrared) remote control system. It's built around a Microchip ATTINY2313 microcontroller (U1) and boasts five push-button switches, an indicator RED LED and an electret buzzer for user interaction. An ISP header provides programming capabilities. The project is battery-powered and implements boost converter TPS613222AD (IC1) for stable power supply. #project #Template #projectTemplate #lock #keypad #attiny2313 #TPS613222A #ISP #buzzer #reusable #module #simple-embedded #microchip #arduino #sublayout
