Create a burglar-tripwire with the ultrasonic sensor.

Intelligently reduce the moisture in your basement/crawlspace to help control mildew growth and lower your heating/cooling bill.

How long were we released from the gravity of the Earth? This machine measures how many seconds we are zero gravity state.

As the title says, this is a pretty simple PIR motion controlled relay using an Arduino Nano.

The ElectronicsLovers Tech Team built this module, which has one difference from a usual one: it’s digital.

During the summers, many people get sunstroke because of playing in the sun for too long. So this device will prevent getting sunstroke.

UltrasonicEyes is a fun and quirky project you can place somewhere and watch as it looks at things moving around in front of it. Freaky!
