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...
