The hardware setup shown below includes the Arduino Uno R4, a DHT11 sensor, and the built-in Wi-Fi for email alerts. The DHT11 is connected with VCC to 5V, GND to ground, and the data pin to Digital ...

In this video I'll be showing you how you can control the contrast and the back light brightness of a 1602 LCD display with just the Arduino. The contrast is typically adjusted with a variable ...

This section defines the network credentials and server details required for sending the email. The ESP32-CAM connects to WiFi using the SSID and password. The host address, HTTPS port (443), and API ...

Arduino has just announced the Arduino Matter Discovery Bundle (AKX00081), an all-in-one development kit designed to help ...

Today I learned that WiFi and Bluetooth LE could NOT be used simultaneously on Arduino boards featuring the ESP32-based u-blox NINA-W102 wireless module, ...

Minecraft remains one of the best games of all time over a decade on from its release, but spending such a long time in one game could lead to you running out of ideas. We've been there: you've ...

The library gives control over up to 16 parallel working PIR devices over I2C. The idea for this library came up in a discussion about how to fully cover an area with PIR sensors without blind spots ...

Abstract: Passive infrared (PIR) sensors are widely used in motion sensing and lighting control. However, stationary occupants always trigger false-negative detects of PIR sensors and result in ...

Abstract: In this paper, we use a modified passive infrared radiation or pyroelectric infrared (PIR) sensor to classify 5 different human motion events with one additional “no action” event. Event ...
