In the spring every year, we have a group of robins who start making nests around the house. We also have lots of windows in a patio area that when the robins see their reflection they think it’s a rival bird. They attack the windows repeatedly for months. They land on the chairs, railing and […]
The Optoelectronics group of Vishay Intertechnology, Inc. (NYSE: VSH) today introduced a new proximity sensor that offers a sensing distance of up to 30 cm. Combining an IR emitter, photo detectors for proximity, amplifiers, and ADC circuitry into a single package, the Vishay Semiconductors VCNL3040 features a programmable interrupt function and supports the I²C bus communication interface
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
In his blog, Charalampos describes his experience with SeeedStudio’s Grove Ear-clip Heart Rate sensor and Cosm (former Pachube) cloud service. The employed sensor is quite cheap and can detect heart pulses from the ear lobe, by measuring the infra-red light reflected by the tissue and by checking for intensity variations. By connecting this sensor with an ADK board
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
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

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

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
