DIY Frugal CO₂ Sensor: Arduino & inexpensive parts to build a sub-$100 system to track and evaluate COVID-19 risk using CO₂ levels to estimate ventilation and occupancy.

The first version was an Arduino Uno, a protoshield, a TFT display shield, and a Mikroe EEG Click with what are really ECG leads and sticky electrodes. This worked fine, but the code kept crashing ...

We’ve seen a few cool hacks for mainstream commercial EEG headsets, but these are all a tad spendy for leisurely play or experimentation. The illumino project by [io] however, has a relatively ...

Build a simple LPG gas leakage detector using Arduino and MQ-5 sensor. This beginner-friendly project features buzzer and LED alerts, circuit diagram, and complete Arduino code for home safety.

[mircemk] shows how to create a simple non-contact proximity sensor using little more than an Arduino Nano board, and a convenient software library intended to measure the value of capacitors. The … ...

Create a smart blind stick using Arduino to help visually impaired individuals navigate safely. This DIY project uses an ultrasonic sensor, buzzer, and LED indicators to detect obstacles and provide ...

Watch the video below to learn more about this awesome DIY Arduino watch that uses a GY-87 sensor board, that offers three sensors in the form of HMC5883L for the compass, BMP085 for the pressure ...
