In this video, I'm exploring the use of Mini PIR Sensors with ESP32 with both Arduino-based projects as well as making a movement sensor for Home Assistant by using ESPHome. The sensor is quite ...

In this tutorial, you will learn how to send WhatsApp messages directly from an Arduino UNO R4 WiFi using the CircuitDigest Cloud Whastapp API. Instead of using a GSM module, SIM card, or complex ...

Hello Hackers! Today we have a really interesting topic. Searching the internet, I didn't find any simple solution on "How to read data from car parking sensors," so I decided to write a short and ...

The sensor continuously sends out infrared light and measures how much of that light is reflected. When a reflective object is within its set detection range, it returns a low signal. The Arduino ...

Abstract: This research aims to develop a RADAR system using an ultrasonic sensor (HC-SR04), servo motor (SG90), and Arduino UNO. This RADAR system can detect objects in the vicinity and display ...

The P0118 code means that the engine control module (ECM) has detected a voltage signal that’s too high from the engine coolant temperature (ECT) sensor (below). In practical terms, the ECM believes ...

Carlo Gavazzi has launched three new series of ultrasonic sensors with integrated IO-Link communication: the UA12, UA18 and UA30 ASD..IO Series. These sensors feature a compact design with reduced ...

I built a mini radar system using Arduino UNO, HC-SR04 Ultrasonic Sensor, and SG90 Servo Motor, paired with a JavaScript-based visualization dashboard 🖥️. The servo sweeps from 0° to 180°, collecting ...

As robots increasingly enter human spaces, robotics companies will need to think about safety differently than they did when robots were largely siloed from their human counterparts. Sonair thinks its ...

According to a new report, the Pixel 10 series may feature a faster ultrasonic fingerprint sensor. The upgrade builds on the tech introduced in last year’s Pixel 9 phones. Other rumored features ...

Hi, I'm Bill. I'm a software developer with a passion for making and electronics. I do a lot of things and here is where I document my learning in order to be able to inspire other people to make ...
