Why buy one when you can build it cheaper?

The Turtle Bot is one of the classics for Arduino tinkering. The YouTuber UncleStem has built it seven times larger – and it works. The hobbyist and YouTuber UncleStem has built the often-replicated ...

Instead of sticking with the typical tabletop-scale builds, Arduino hobbyist and YouTuber UncleStem chose ...

The sensor continuously sends out infrared light and measures how much of that light is reflected. When a reflective object is within its set detection range, it returns a low signal. The Arduino ...

Is the Arduino Uno Q the missing piece in your next project? With its hybrid design that fuses the precision of a microcontroller with the flexibility of a Linux-based single-board computer, this ...

Looking for practical Arduino projects? This guide shows how to control a relay from your smartphone using an Arduino Uno — either via Bluetooth or Wi-Fi with an ESP8266 ESP-01 module. With ...

Spectroscopy seems simple: split a beam of light into its constituent wavelengths with a prism or diffraction grating, and measure the intensity of each wavelength. The devil is in the details, though ...

The working principle of the water level sensor module is very similar to that of a Rain Sensor. The water level sensor has three pins, runs on 5V power, and gives out the data in analog format. 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 ...

Programming this versatile microcontroller efficiently can significantly impact the success of your projects, whether you’re working on IoT applications, automation, or educational experiments. This ...

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 ...
