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…
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…
On-line shopping has changed the way goods are acquired. For most packages it is not necessary to be around for the dropoff. But… for the important stuff it is. Those packages always seem to show up right when you are in the backyard for mere seconds causing that frustrating “Personal Signature Required for Delivery” note on the…
It happened to everyone, you buy an avocado, it’s not ripe yet. A few days pass by, and by the time it’s ripe you have forgotten about it… and in a few days, it may go bad! lucky for you we designed and built AvoRipe, a device that checks your avocado twice a day, or…
Stopwatches are very useful in several applications and made by yourself using an Arduino, it is really more interesting! This project is really simple, easy to be assembled using few components and has an excellent accuracy and responsiveness including the following features: The stopwatch shows the time in minutes, seconds and tenth of seconds. The…
The art of firebending as seen in Avatar: The Last Airbender and The Legend of Korra is a melding of Asian martial arts and pyrokinesis. So how can we control fire with fancy fight moves in real life? With Arduinos, of course! The flamethrower part of this project is composed of a butane fuel…
This is a mini project I made for fun. It was done at the beginning of this year and I thought I should share the story behind the making of this. It’s a cactus that tweet when it needs water :P. The idea started as an inspired project. I was watching a ted talk…
With the recent discontinuation of the SmartShield attachment for the Arduino. The Samsung SmartThings community has been looking for a replacement for this shield. This project presents the start of a solution to this, using the Arduino wireless shield and a Xbee series 2C to create a simple switch. The switch can control the…
In this example we have tried to send and receive data from a database in real-time in Firebase, learning how to create the DDBB, the application in Arduino, and then finally to access it from a mobile application created with App Inventor. Let’s see each part in detail. More info
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! …
The seismometer is a device for the detection of earthquakes and measuring their strength. Basically these are very precise instruments and are relatively difficult for self-construction. Commercially available sensors are very expensive, and cheap electronic modules sensitive to shocks are not sufficiently sensitive to this purpose. In the text and video that follow, you…
