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 ...

Wearable technologies are starting to reshape how people manage health. Continuous glucose monitors that measure blood sugar ...

In this video I'm walking you through the steps I took to make a standalone version of my pellet level monitoring sensor that is not directly connected to Home Assistant but it functions separately .

The last week of the release continued the same “lots of small fixes” trend, but it all really does seem pretty benign, so I’ve tagged the final 7.0 and pushed it out. I suspect it’s a lot of AI tool ...

MicroPython is a well-known and easy-to-use way to program microcontrollers in Python. If you’re using an Arduino Uno Q, ...

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 ...

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 ...
