Create a pressure sensor using: – Needle-felted wool – Thin muslin – Velostat – Conductive thread This sensor can be used an analog input for Arduino code. Step 1: Prepare the Core Components Component 1: A felted wool ball. This can be made using unwoven wool (I used Leicester wool), a felting needle, and a […]

Why is it so hard to remember to use hand sanitizer between going into the store and driving back home? We tried hanging a bottle off the windshield wiper stalk, but it gets in the way and is hard to use and share with passengers. The ideal thing would be to have a hands-free pump in

In this tutorial we’re going to play with a gesture sensor (APDS-9960) and a neopixel ring to learn how to combine them both using an Arduino UNO. The end product will respond to left – right gestures by animating led movement right or left, and to up-down gestures by changing leds color. In the next

I recently built a simple 8 key piano using an original NES controller and Arduino UNO board.Unlike conventional Arduino piano projects which require one digital pin for each key / button the NES controller piano used only three digital pins (D5 for nesClock, D6 for nesLatch, D7 for nesDataIn) leaving 5 extra digital pins available for experimentation.

The Internet of Things (IoT) is creating many new exciting application opportunities to create smart environments where sensors monitor for changes so that the appropriate actions can be taken. The fastest growing examples of this are HVAC (Heating Ventilation and Air Conditioning), IAQ (Indoor Air Quality), smart homes and smart offices where a network of sensors monitors temperature and

This is a pill dispenser robot able to provide the patient the correct amount and type of medicine pills. The dosing of the pill is performed automatically at the correct time of the day, preceded by an alarm. When empty, the machine is easily refilled by the user. The dispensing and refilling mechanism is controlled

Hi everyone, this is my second instrucatable! This time we are going to build a wooden clock with temperature and humidity display. Like shown in the picture, our the time will be displayed through the “wood”. Since light isn’t strong enough to pass a piece of wood, we are going to use wood texture vinyl stickers

Ultra-compact high reliability design eliminates heat generation, improving safety and energy savings in industrial equipment ROHM has recently announced the availability of the industry’s smallest contactless current sensor, the BM14270MUV-LB. It achieves minimum power loss (no heat generation) in an ultra-compact size, making it ideal for industrial equipment and consumer devices that detect operating conditions via
INDUSTRY’S SMALLEST CONTACTLESS CURRENT SENSOR FEATURING MINIMUM POWER LOSS Continue Reading
NVE Corporation announced the new SM124-10E Smart Magnetometer. The new sensor combines a Giant Magnetoresistance (GMR) sensor element with elegant digital signal processing. The versatile product can be used for current or proximity measurements. In-Plane Sensitivity Unlike awkward, old-fashioned Hall-effect sensors, GMR is sensitive in-plane for optimal current sensing and easy mechanical interfaces. A Slick,
