Abstract: We connected $\mathbf{p H}$ sensor and solar cell into Arduino Board to control data transmission via red laser communication or popular known as visible light communication (VLC). The ...

I recently had to build an infrared close proximity sensor that could tell if something was dropped in a parcel delivery drop box. After some searching, I ended up using a microcontroller and a piece ...

Why is pH measurement important in paints? The pH level of paint can affect its properties such as viscosity, drying time and color. A high pH level can cause the paint to become too thick, dry too ...

Arduino libraries, like libraries for other programming languages, help easily extend the range of functions available to users in the standard integrated development environment (IDE). They are ...

Are you a researcher who understands the significance of precise pH measurements for your experiments? As minor errors in pH measurement can have a detrimental impact on your research, it's essential ...

Today, We will review the Cytron Maker Uno RP2040 development board combining the Arduino UNO form factor with the Raspberry Pi RP2040 microcontroller that makes it programmable with the Arduino IDE ...

(Nanowerk News) Measuring the pH of substances gives us vital clues about the world around us, such as identifying contaminated water or checking the toxicity of medical or cosmetic products. Often, ...

A prototype designed to neutralize acidic water, improving the pH levels to a safe range. Our solution employs an Arduino UNO, pH sensor, peristaltic pump, LCD display, and a volume input keypad.
