This is a simple arduino project for a soil moisture sensor that will light up a LED at a certain moisture level. It uses Arduino Duemilanove microcontroller board. Two wires placed in the soil pot ...

After some searching, I ended up using a microcontroller and a piece of code borrowed from the web that I tweaked and adapted. The microcontroller-based concept was chosen because I wanted to scale ...

As a biomedical equipment technician [Adam Outler] equipment needs to be in top working condition. The emergency room staff were complaining about erroneous noise on the electrocardiogram and it&#8… ...

As much as we love the Arduino Uno, it's not the most powerful of hobbyist microcontrollers. Fortunately, the folks in Turin have just put the finishing touches on a 32-bit upgrade with buckets of ...

Ever thought of using touch sensors on your projects but didn’t because it would be too much work? [Paul Stoffregen] proves that it can be pretty easy if you use the CapSense library for Arduino.

In this particular project, I contemplated a shield for Arduino Nano, which can gather weather-related information by a built-in BMP280 Temperature and Pressure Sensor, a photoresistor, and a ...

Use Arduino to handle sensor input and relay control. Pi runs a Python Flask server with a simple UI to toggle GPIO pins via serial commands sent to the Arduino. Use cron jobs on Linux to schedule ...
