- 15. Coding loops and working of UNO Void loop() Next to explain it void setup() { // put your setup code here, to run once: pinMode(lSinput, INPUT); pinMode(mSinput, INPUT); pinMode(rSinput, INPUT); pinMode(rMU3, OUTPUT); pinMode(rMD4, OUTPUT); pinMode(lMU1, OUTPUT); pinMode(lMD2, OUTPUT); }
- 16. Code Partition of the Project First Partition if (rin==LOW &&(lin== LOW)&&(Min== HIGH) ) // move forward { digitalWrite(lMU1, HIGH); digitalWrite(lMD2, LOW); digitalWrite(rMU3, HIGH); digitalWrite(rMD4, LOW); }
- 17. Second Partition if (rin==LOW &&(lin== LOW)&&(Min== LOW) )// move back { digitalWrite(lMU1, LOW); digitalWrite(lMD2, HIGH); digitalWrite(rMU3, LOW); digitalWrite(rMD4, HIGH); }
- 18. Third Partition if(rin==HIGH &&(lin== LOW)&&(Min== LOW) )// move RIGHT { digitalWrite(lMU1, HIGH); digitalWrite(lMD2, LOW); digitalWrite(rMU3, LOW); digitalWrite(rMD4, LOW); }
- 19. Fourth Partition if(rin==LOW &&(lin== HIGH)&&(Min== LOW) )// move LEFT{ digitalWrite(lMU1, LOW); digitalWrite(lMD2, LOW); digitalWrite(rMU3, HIGH); digitalWrite(rMD4, LOW); }
- 20. Conclusion We have concluded that we can make any desired robot by using microcontroller like in our project, we have used Arduino UNO R3 and given it some particular instructions from the code which you have seen in our methodology. This project enhance our knowledge and working skills regarding H-bridge and motor function, and also motor driving with the help of Arduino and L293D.
