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 can ...

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 ...

ATtiny85 Dev Board
Misiek_86 Apr 22,2022
Hi, I would like to present another project. A board for ATtiny85. This is a board to be able to start with a microcontroller, the usb connector allows you to use VUSB after uploading a proper bootloader. Additionally a reset button was added to the board.List of elements: Capacitor (SMD 0805):C1 - 4.7uFC2, C3 - 100nFResistor (SMD 0805):R1, R2 - we choose according to LED color, I suggest 330RR3 - 1.5kR4, R5 - 68kDiode:D1, D2 - LED (SMD 0805)D3 - MBR0520LTD4, D5 - 3.6V ZenerPinHeader, usb m...

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...

Non-contact Infrared temperature sensor using Arduino
Manoj kumar Apr 17,2022
Hello guys, I want to make my own most accurate temperature meter. When coming to the high temperature measurements, PT1000, PT100 and K-type thermocouple can be the solution. But the problem is big and messy wires between the Microcontroller and sensor. These wires are not waterproof and heatproof. The analog sensors are not too much accurate and take a long heat-up and cooldown time.So, keeping all the factors and requirements in mind. I decided to go with MLX90614 Infrared Contact-less temper...

Mini Matrix
Arnov sharma Apr 16,2022
Hey What's up folks, this is my tiny 8x8 Matrix that is made from 64 WS2812B LEDs that are in the 2020 package.The Goal for making this matrix was to prepare a custom 8x8 matrix that I could use in small projects, the matrix available in the market uses Addressable LEDs of the 5050 package which would be too big for my application so I prepared my own by using smaller LEDs and a Custom PCB.The size of this Mini Matrix is 28.6 x 26.4 mm which is crazy small.This article is gonna be about how I ma...
