Nodal Voltage Analysis
Learn what is Nodal voltage analysis and how to use it a circuit network:https://circuitdigest.com/tutorial/nodal-voltage-analysis
Frequency to voltage converter converts the frequencies or pulses to the proportional electrical output such as voltage or current.It is an important tool for electromechanical measurements where repeated events are occurring.So,when we provide a frequency across a frequency to voltage converter circuit,it will provide a proportional DC output.Here we are using KA331 IC to build a frequency to voltage converter circuit.
In this DIY tutorial we use the same MCP4725 DAC IC to design a Digital to Analog converter usingRaspberry Pi.Check out the tutorial here:https://circuitdigest.com/microcontroller-projects/raspberry-pi-mcp4725-dac-tutorial
In this project,we are controlling aServo Motorusing a web browser with the help of Arduino and ESP8266.ESP8266 wi-fi modules is a cheap and powerful device,helps in communicating with any microcontroller,like here Arduino UNO.

In this DIY project,we use Arduino andUltrasonic Sensorto build an Obstacle Avoider.Here an Ultrasonic sensor is used to sense the obstacles in the path by calculating the distance between the robot and obstacle.If robot finds any obstacle it changes the direction and continue moving.
As ESP modules become synonyms for Wi-Fi applications,this LoRa technology also has caliber to build a vast network like Internet.We previously build manyIoT Based projects using ESP8266 and Arduino,here in this article we will learn vwin滚球官网about LoRa and how to use it with Arduino Development Platform.
