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 ...

In this video I've created a device that can notify in real time about events that happen on a website. The project uses NodeMCU board and a buzzer to produce sound as alert. The board is programmed ...

It’s pretty easy to take a balloon, fill it up with helium, and send it up in to the upper atmosphere. It’s much harder to keep track of it and recover it when it falls back to Earth. If you’re trying ...

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, ...
