Wemos D1 Multishield Arduino
Apr 22,2022
Project OverviewThe shield consists of a temperature sensor, a motion sensor, an LDR, and a 3 pin socket where you can connect any output, we’ll be using a relay module.We’ll also write a program that runs a web server to control the shield using 4 different modes with several configurable settings.Automatic motion mode, meaning that when it detects motion the relay stays on for a determined number of seconds.Or you can use the luminosity mode, so the relay turns on when the light goes below a…

Reflow hot plate controller board
Curious Scientist Apr 22,2022
Description:This project realizes a custom made reflow hot plate controller. I made a fancy graphical user interface for programming the heating curve and displaying the temperature in real time. The programmable reflow curve and the real-time time vs. temperature graph is shown on a 1.8" LCD. All the parameters can be set with a rotary encoder. The temperature is measured with a thermocouple via a MAX6675 module. The system also contains two outputs for fans, so at the end of the heating progra…

Arduino Location Tracker
Apr 22,2022
Introducing the NEO-6M GPS ModuleThe NEO-6M GPS module is shown in the figure below. It comes with an external antenna, and does’t come with header pins. So, you’ll need to get and solder some.This module has an external antenna and built-in EEPROM.Interface: RS232 TTLPower supply: 3V to 5VDefault baudrate: 9600 bpsWorks with standard NMEA sentencesThe NEO-6M GPS module is also compatible with other microcontroller boards. To learn how to use the NEO-6M GPS module with the Raspberry Pi, you ca…

Attendance System With Arduino & Rfid Tag
Apr 22,2022
MFRC522 RFID ReaderIn this project we’re using the MFRC522 RFID reader and that’s the one we recommend you to get (although this project may also be compatible with other RFID readers).RFID means radio-frequency identification. RFID uses electromagnetic fields to transfer data over short distances and it’s useful to identify people, to make transactions, etc.An RFID system needs tags and a reader:Tags are attached to the object to be identified, in this example we have a keychain and an elect…

SHROOM from Super Mario
Arnov sharma Apr 20,2022
Hey what's up guys, this is the SHROOM PCB Badge that is themed after SHROOM from Super Mario.This wearable Badge is made completely from PCB I got from PCBWAY and is powered by an Attiny85 which is in the SOIC8 Package.I added three WS2812B LEDs to this badge which are visible from the front side of the board.These LEDs are placed in an inverted position so their glow will be visible from the front side through the soldermask opening I left in both layers.This article is gonna be about how I ma…
