In this post we are going to learn how to build a RFID based attendance system using Arduino development board, RC522 RFID reader module and external EEPROM. We will take a brief look at RC522 RFID module, external EEPROM and other circuit modules that makes this proposed RFID attendance system work. RFID card based…
In this project, we’ll create a status indicator PCB shield for the ESP32 featuring two rows of addressable RGB neopixel LEDs, a BME280 sensor, and a pushbutton. We’ll program the board to display a web server with the BME280 sensor readings and show the temperature and humidity range on the LEDs (like two progress…
In this project we’ll create a PCB shield for the ESP32-CAM AI-Thinker board with a PIR motion sensor, a BME280 temperature, humidity and pressure sensor and some additional exposed pins. We’ll create a Telegram bot for the ESP32-CAM that allows you to control your board from anywhere to request a photo, sensor readings or…
Hey Geeks, Now I am studying in +2 which is equivalent to 12th Grade. I am very interested in computer science and also my main subject is that. I spent a lot of time in developing Embedded projects. I have around 3 years of experience in the embedded field. I always focus on innovative…
Most cars use the CAN (Controller Area Network) communication protocol to enable communication between different devices. The goal of this project is to replace data from the radio with others from Arduino Nano, in order to visualize other data on the display. To do this, a custom PCB based on Arduino Nano, a TJA1055 and…
Today I am going to show you, how I build a “Racing Game Simulator” with the help of Arduino UNO. The working is very simple Arduino is use as a HID device that can communicate between computer and external componentdevices More info
I started this as an academic exercise, but ended up with a very accurate clock. After running for 5 days, it had not lost or gained any time. The main issue with using just an Arduino is that its internal clock speed is not 100% accurate. Hence if you just rely on this then…
In this project we are going to learn how to build an infrared based non-contact thermometer which can be utilized for screening people at schools, offices, shopping malls etc. for abnormal body temperature which could be a sign of contagious diseases. The proposed non-contact thermometer can measure body temperature of a person at forehead…
https://youtu.be/2FcOQE6c_SA Nowadays USB port is used widely for data transactions between electronic devices and computers. In many scenarios, there is no need to communicate with the USB port directly, therefore electronic designers use USB to UART (RS232-Serial) converter chips, so the USB port is converted to a virtual COM port on the computer. The…
What is Piunora? Piunora is a development board complete with IO headers, USB ports, and HDMI output. It has an M.2 connector, some built-in LEDs, a camera connector, and a few other features. It also opens up some new functions, such as the ability to run the Pi as a USB gadget rather than…
While the Arduino IDE provides a simple and clear interface that is ideal for novice users, the more advanced users often report that the editing capabilities are a bit limited compared to modern editors. This includes features like code indentation, block folding, auto-closing brackets, regular expression search and replace, comment toggling. In addition to this, many…
Technology is becoming a crucial part of every industry and is spreading its wings in the world. With the technical advancements, the robotics industry is also providing its services in several forms. Medical Robots are there in the medical industries that help several organizations manage patients and their data efficiently. But still, there are multiple…
