Abstract RADAR is a system that detects objects by using radio waves to measure the distance, height, position, or velocity of objects. Radar systems are available in a range of sizes and come with various performance specifications. Certain radar systems are employed for managing air traffic at airports, while others serve for long-distance surveillance and […]
Update: The Arduino system is fine; the only thing you have to take into consideration is the 9.54 hour rollover event, which Rob Faludi has provided an excellent solution for here. I made up a nice little over-analysis of the issue, available here. For a while, I’ve wanted to make a clock that can change […]
Greetings to all, we welcome you back to Techatronic. During today’s meeting, we will discuss the development of a smart water heater project that involves Arduino and DS1820B temperature sensors. If you’re interested in creating a mobile smart water heater for the winter, then this project is perfect for you. This new technology can be […]
Introduction Hello everyone, I hope all of you are doing well. This article gives guidance on constructing a circuit to control a stepper motor using an Arduino UNO and the ULN2003 motor driver. Listed below are three circuit diagrams along with their corresponding codes. You are free to choose and customize any of these circuits […]
This project demonstrates building a real-time clock (RTC) with temperature display using an Arduino, DS3231 RTC chip, and SSD1306 OLED display (128×64 pixels). The DS3231 RTC chip provides more accuracy than the DS1307 and incorporates an onboard temperature sensor. It maintains timekeeping even without the main power, making it well-suited for this application. It communicates […]
In modern-day society, an increase in rail passengers means that rail companies must do more to optimize networks to keep up with the demand. In this project we will show on a small scale how temperature, rainwater, and vibration sensors on an arduino board can potentially help increase the safety of passengers. This Instructable will […]
Today, I constructed a compact 3x3x3 LED cube utilizing an ATtiny2313 that I acquired around 2 weeks ago. Every time I wanted to update the LED cube with better patterns, I had to bring out my breadboard, reconnect everything following ATtiny2313 pin-outs, and upload the updated code. I proceeded to search on eBay and Amazon […]
Eventually you are going to find yourself holding a 12v solenoid, motor, or light and wondering “How the heck am I supposed to control this from my Arduino?” And we have covered this in the past. Today we are going to talk about another way of doing just that, this time with an N-Channel MOSFET […]
Electrical appliances, such as smartphones chargers and room heaters, play a crucial role in our everyday routines. This includes larger devices like air conditioners and washing machines. With the ongoing worldwide energy crisis, it is essential to understand the electricity usage of these devices. Although our monthly electricity bills give us a broad view of […]
Have you ever faced this situation while sitting on your favorite spot on the couch or recliner, comfortably watching your favorite TV program? You’re snugly tucked under the blanket, the air conditioning is pleasantly cool, the sun outside is shining it’s delicate warm golden rays on the closed window, the air (from the air vents) […]
