   5HP Motor speed control by arduino. By using Arduino we control 5HP Dc motor in easy way CIRCUIT DIAGRAM : ARDUINO CODE: #include <LiquidCrystal.h> LiquidCrystal lcd(12, 11, 5, 4, 3, 2);   const int currentPin = A0; const int pot=A1; int sensitivity = 66; int adcValue= 0; int adcValuee= 0; int offsetVoltage = 2500; double adcVoltage = 0; double currentValue = 0; double sensorValue=0; int ledPin=13; float ton=0; float toff=0; float duty=0;   void setup()  {   Serial.begin(9600);   lcd.begin(16, 2);   lcd.print("DC speed control ");   lcd.setCursor(0,1);   lcd.print("  with Arduino  ");   pinMode(ledPin,OUTPUT);   delay(400);    lcd.clear(); }   void loop() {      adcValue = analogRead(currentPin);   adcValuee = analogRead(pot);         ton=1024-adcValuee;      toff=adcValuee;     float y=ton=+toff;      float xx...
