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. LM393 Soli Moisture Sensor Module(over view)  Components Required: LM393 Soil Sensor  NodeMcu(ESP8266)  Connecting wires(male to male)  Breadboard  Follow the Image below for circuit connection reference:- (Interfacing all components)  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 th...

Hey Folks, In this tutorial, we will learn how to interface a Seven Segment Display with ARM(FRDM-KL25Z).
