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…
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…
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…
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…
https://www.youtube.com/watch?v=fG55OmGgqmQ&feature=youtu.be&ab_channel=PCBWay A sensor converts data such as heat, light, sound, and motion into electrical signals. These signals are passed through an interface that converts them into a binary code and passes this on to a computer to be processed. Today, let’s see how makers use plenty of sensors to build their awesome projects! …
Just when we think we’ve peeped all the cool baby keebs out there, another think comes along. This bad boy built by [andyclymer] can be configured three different ways, depending on what kind of control you’re after. As designed, the PCB can be used as a six-switch macro keyboard, or a rotary encoder with two…
As part of our studies at Polytech Sorbonne, this is a project of embedded system. We designed a system for measuring various parameters of plants on a roof and then apply it to the study of the relationship between solar panel efficiency and plants for the agri-food section of our engineer school. Our device is…
Unfortunately, the Coronavirus problem is also affecting PCB production. Our friends of JLCPCB have informed us that the situation is returning to normal and that production has suffered delays that aim to recover shortly. Since the outbreak of the novel coronavirus epidemic, the Chinese government has been taking the most comprehensive prevention and control…
