I'm trying to provide analog control to a Bluetooth controlled car, via Arduino. I have joystick app (as the pot). It send values between 0 to 255 So I'm thinking... Whether this flow down here 👇 will work?
Joystick app --> Bluetooth Rx --> DAC --> Vs pin of L293D. Or motor?
Is Arduino required at all? Or is the serial word enough to translate into voltage via DAC?
