This is an Arduino-based Proximity Sensor circuit wired using the popular HC-SR04 Ultrasonic ranging module,used here for non-contact object detection purpose. The HC-SR04 module includes ultrasonic ...

[Klaus] wanted some sort of aid for parking his car, and after running across a $4 ultrasonic sensor, decided to build his own speaking distance sensor (.de, Google Translation). Inside [Klaus]’ ...

The Turtle Bot is one of the classics for Arduino tinkering. The YouTuber UncleStem has built it seven times larger – and it works.

The main goal of this application is to design an ultrasonic qualitative distance estimation sensor using Dialog Semiconductor’s SLG47105V. The system is designed using high-voltage (HV) macrocells ...

As the world struggles with the impact of COVID-19, businesses and governments are seeking ways to safely restart global commerce and local economies to mitigate the financial impact of the virus.

Inductive sensors are non-contact proximity sensors that detect ferrous targets, ideally ones made of mild steel thicker than one millimeter. They consist of four major components: a ferrite core with ...

Sometimes, it’s time to shut down the oscilloscope, and break out the cardboard and paints. If you’re wondering what for, well, here’s a reminder of an Instructable from [CrazyScience], that brings us ...
