Let me introduce another simple microcontroller-based do-it-yourself circuit that detects motion and excites a light source in a flash. The “snooper” here is an ordinary passive infrared (PIR) motion ...

An Arduino library for the Hi-Link HLK-LD2450 24Ghz FMCW radar sensor. This sensor is a Frequency Modulated Continuous Wave radar, which makes it good for presence detection and has some interesting ...

Recently, I exhausted my stock of common passive infrared (PIR) motion sensor modules and was looking for a new one to play with. I searched the web for a small type with self-contained electronics.

1. Verify & upload the GetSerialNumber.ino sketch to get the board's serial number and print it on the console output. 3. Enter the board's serial number and click Submit. The license data of the ...

The Leap Motion controller is a rather impressive little sensor bar that is capable of generating a massive 3D point cloud and recognizing hands and fingers to allow for gesture control based ...

Before we get started it is important to understand that there two types of nRF24L01 modules available in the market one is called just nRF24L01 and the other is called nRF24L01+ PA+LN. While both the ...

It’s really hard to overstate how awesome ESP8266 development boards like the Wemos D1 Mini really are. For literally a couple of dollars you can get a decently powerful Wi-Fi enabled microcontroller ...
