When I wrote about a DIY ESP32-S3 internet radio last week, "raspbeguy" commented he'd rather choose an ESP32-based DIY DAB+ ...
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 ...
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: A Wireless Sensor Network (WSN) is a distributed set of sensors deployed to work together for collective sensing and possible data processing. A WSN can be used to monitor environmental ...
An automatic toll gate system using Arduino revolutionises traditional toll collection by eliminating manual intervention. The “automatic toll gate system project” demonstrates how simple sensors and ...
The DHT11, 21, 22, 33 and 44 are relative inexpensive sensors for measuring temperature and humidity. This library can be used for reading both values from these DHT sensors. The DHT11 only returns ...
Maria Emanuella Moura Silva for testing and verifying this experimental code on a Galileo. It needs a diode between the input pin of the MCU and the data pin of the DHT sensor. The output pin of the ...
