Hey Folks, In this tutorial, we will learn, how to change the intensity of light using touch sensor the ARM (FRDM-KL25Z).
INTRODUCTION The FRDM-KL25Z is an ultra-low-cost development platform for Kinetis L Series KL1x (KL14/15) and KL2x (KL24/25) MCUs built on ARM® Cortex™-M0+ processor. The FRDM-KL25Z has been designed by NXP in collaboration with mbed for prototyping all sorts of devices, especially those requiring the size and price point offered by Cortex-M0+ and the power of USB Host and Device.The FRDM-KL25Z is supported by a range of NXP and third-party development software.It is packaged as a development board with connectors to break out to stripboard and breadboard and includes a built-in USB FLASH programmer.

Soil Moisture Monitoring using ESP8266 and Soil Moisture Sensor

Hey folks

In this tutorial, we will learn how to interface LM393 module(Soil Moisture Sensor)with NodeMcu(ESP8266). LM393 is a simple water sensor can be used to detect soil moisture when the soil moisture deficit module plant waterer device, so that the plants in our garden without people to manage; Adjustable sensitivity adjust the digital potentiometer (shown in blue) Operating Voltage 3.3V-5V; Module Dual Output mode, a simple.

Components Required:
LM393 Soil Sensor NodeMcu(ESP8266) Connecting wires(male to male) Breadboard  Follow the Image below for circuit connection reference:-

Here Pin A0 of the moisture sensor module connects to pin A0 on the ESP8266
The GND pin on the moisture sensor module connects to a GND pin on the ESP8266
The VCC pin on the moisture sensor module connects to a 3v3 pin on the ESP8266
D0 pin remain disconnected

After making the circuit dump the code given below:-

#include <ESP8266WiFi.h>
const char* ssid = "Enter SSID";
const char* password = …
