This project involves using an Arduino to measure distances using an ultrasonic sensor and controlling a buzzer and LED based on the measured distance. The provided Arduino code performs the following ...

// Tested with green LED an 1 kOhm resistor at pin A5. // LED produce up to 1.4 voltage and 3 micro amps current at light. // The current is very small and messurements don not provide stable results.

Abstract: Drunk driving remains a significant issue worldwide, with thousands of lives lost every year due to accidents caused by individuals operating vehicles under the influence of alcohol. The ...

Description: Using an Arduino or a micro controller, we can generate cool-looking patterns with an led strip containing addressable LEDs. In this case, I'm using an Arduino uno (clone board) and a ...

We've all heard that "if you want something done right, you have to do it yourself." And that’s usually fine when it comes to ...

MicroPython is a well-known and easy-to-use way to program microcontrollers in Python. If you’re using an Arduino Uno Q, though, you’re stuck without it. [Natasha] saves the day by bringing us a a ...

Cardiovascular diseases remain the leading cause of death worldwide, accounting for nearly 20 million deaths each year. Rapid ...

It’s pretty easy to take a balloon, fill it up with helium, and send it up in to the upper atmosphere. It’s much harder to keep track of it and recover it when it falls back to Earth. If you’re trying ...

Optical sensors are a broad class of device for detecting light intensity. This can be just a simple component for notifying when ambient light levels rise above or fall below a prescribed level, or a ...

Abstract: In this work an integrated filter-less BiCMOS based color sensor is presented. It is capable of determining the center wavelength of a monochromatic light source in the visible range. This ...
