• Exam registeration

  When can I register for the exam. Can we register for the exam whenever we are ready or is there a specific date in which we should appear for the exam?. Can I get the complete details about this.

• Kindly explain code line inside if statement

  analogWrite(fwdbuttonState == LOW ? ICpin2 : ICpin7, motorValue);                digitalWrite(fwdbuttonState == LOW ? ICpin7 : ICpin2, motorValue);kindly give explanation for these two lines, how can we change directions we have not used bckbuttonState variable.

• Doubt in tutorial Pulse width Modulation

  At time 9: 30 in the tutorial the input to the Function map (potvalue, 0,1023,0,255) is not explained. and At time 9: 45 in the tutorial the input to the Function analogWrite (fwdbuttonState == Low ? ICpin2: ICpin7,motorvalue); digitalWrite (fwdbuttonState == Low ? ICpin2: ICpin7,motorvalue);is not explained properly..Thanks!

• how digital value can be written by analogWrite command?

  analogWrite(fwdbuttonState == LOW ? ICpin2 : ICpin7, motorValue);in above line how motor value (digital value) can be written by analogWrite cammond?also in video two line are as analogWrite(fwdbuttonState == LOW ? ICpin2 : ICpin7, motorValue);digitalWrite(fwdbuttonState == LOW ? ICpin7 : ICpin2, motorValue);whereas in source code lines are as analogWrite(fwdbuttonState == LOW ? ICpin2 : ICpin7, motorValue);digitalWrite(fwdbuttonState == LOW ? ICpin7 : ICpin2, LOW);why discrepancy like this ?also why you have used analogWrite in above line and digitalWrite in below line? why it is not digitalWrite in both lines?relpy soon...

• Logic of the program.

  Would you please explain the if condition of the program and why was it used? Also why we are using digitalWrite in the conditional loop and also what does "if fwdbuttonstate==LOW?ICpin2" and "if fwdbuttonstate==LOW?ICpin7" means??

• Conditional statements in if else

  In the if statements there r two functions analogwrite() & digital(), analogwrite() is to power up the selected icpin2/7 depending on the conditional logic, with motor value but idint understand why u r using digital wrte()

• Can we give potentiometer value via program

  Sir,I have a small doubt that can we give the potentiometer value through arduino code itself instead of rotating the knob of potentiometer.   If so please let me know.
