It’s now about six years since Star Wars: The Force Awakens first showed us the little spherical robot BB-8, but it’s fair to say that along the way we’ve not lost our collective fascination for rolling-ball robots. There have been plenty of attempts to make a fully-rolling device, but perhaps [Derek Lieber] has a better take on […]

Hello there! I hope you all are fine and in good health. This instructable is about making your own current sensor that is compatible with Arduino and most other widely popular microcontrollers. This project features a compact design and an all SMD component based circuit, making this sensor module very compact for it’s range. This

Counting change is a great way to teach children about mathematics and money, but it grows tiresome for those of us that have passed the first grade. Thus, a machine should the job, as [Daniele Tartaglia] demonstrates. A vibrating motor is used to shake a hopper full of coins, letting them fall through a feeder slot

Lightning is a force to be reckoned with: ever since ancient times, humans have been in awe of the lethal power of lightning strikes and the deafening roar of thunder. Quite reasonably, they ascribed these events to acts of angry gods; today, modern science provides a more down-to-earth explanation of the physics involved, and a

Note: this sketch is a work-in-progress and only partly tested. This multi-file sketch is provided to serve as a template for projects which combine responsive sensing and actuation with behavioral logic, implemented using a non-blocking event loop. The actual sketch does nothing specifically useful, but just exercises various sensors and actuators. This is in keeping

N.B. this is new and still being tested. This sketch demonstrates an example of ultrasonic range sensor data processing using a combination of signal filters and a classification tree. The classifier code was generated using the Python script classify_gen.py on recorded and labeled training data. The underlying classification tree was automatically generated using the Python scikit-learn library. For more
