Overview In this article, we will dive into the exciting world of ESP32 BLE on the Arduino IDE, exploring how to easily connect your Arduino with other BLE devices. Whether you want to create a wireless sensor network, control your smart home devices, or build a mobile app that interacts with your Arduino, the ESP32 BLE module has got you covered. The ESP32 BLE module is a versatile and powerful Bluetooth solution that allows for fast and efficient communication between devices. With its low energy consumpt...

There are several examples in Arduino IDE to help you get up and running with Arduino boards. In this tutorial, you will learn about each of them. 1. Basics Analog Read Serial: To read the value of a potentiometer and to display it in the Monitor Serial. Bare Minimum: To create a simple sketch with the most basic parts of the coding (setup and loop). Blink: Turns an LED on and off flashing. Digital Read Serial: Reads the status of a switch and displays it in the Monitor Serial. Fade: To...

Double-sided Touch Sensor Features There is a wide variety of touch sensors. One of these sensors is double-sided touch sensor with 3-pin and 4-pin interface on each side. Pin N in 4-pin interface is not used. Note Pin S is always HIGH and changes to LOW if the switch is touched. (If not touched, it will be HIGH again.) Double-sided Touch Sensor Pinout This Module has 3 main pins:VCC: Module power supply – 3.3/ 5 VGND: GroundS: Sensor output (5V)N: Not us...

Character LCD Display Features Character display module is an LCD module with a certain number of rows and columns, and has a green or blue backlight and white character. These displays can usually be used to display text, characters and numbers. The contrast can be adjusted by connecting a potentiometer to pin 3. Pin 15 and 16 are for backlight. You can use 6 pins E, RS, DB4, DB5, DB6, DB7 to interface the display with Arduino. You can download the datasheet of 2004 C...
