Rc car Bluetooth control and manual control

Using Arduino Programming Questions
#1

I want to control rc car in two operations control like Bluetooth control & manual. In this function i am using two (motors1 for forward and reverse),(motor2 for left and right)
Requirements
Bluetooth control :
*control motor1(forward & reverse)
*control motor2(left & right)
Manual control :
*control motor1(forward & reverse)
*motor2 no need

Problem
After adding the code for manual control. my bluetooth control also not working only left & right Working

Hi Dhanavignesh,

I have made a few adjustments to your code.

I am not sure if it will work but please give it a go!
