In this guide, we will explore the DHTesp library, a powerful tool for interfacing with DHT temperature and humidity sensors in Arduino projects. The library works for Arduino, ESP8266 and ESP32.
The code for the ESP32 using the DHT11, DHT20, or DHT22 is identical to the Arduino example in the previous chapter. You just need to modify the connected OUT pin or the SDA and SCL pins. Also, ...
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 video I'm building an Arduino Heart Rate Monitor that is housed in a toy handle in the style of the Star Trek Tricoder. The device uses the PulseSensor with an Arduino Pro Mini and an OLED ...
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, ...
There have been many questions about what direction Arduino would take after being bought by Qualcomm. Now it would seem that we’re getting a clearer picture. Perhaps unsurprisingly the ...
How often have you pulled out old MCU-based project that still works fine, but you have no idea where the original source ...
How Does the ESP32 WhatsApp Alert Message Work? The ESP32 uses its built-in WiFi to communicate with CircuitDigest Cloud WhatsApp API and send WhatsApp notifications whenever a sensor condition is ...
