hello,
I want to make a line follower fire fighter robot so I want to use 2 IR sensors for line limitation and 1 flame sensor to check the flame. The robot has 2 dc motors for moving and a dc motor with propeller for winding to extinguish the fire so which driver (motor shield) I should select to control 3 dc motor and attaching 2 IR sensors and 1 flame sensor to the Uno board? (thanks)
Sounds like a nice project. How far have you gotten?
Can't recommend a motor driver without the motor specifications. Namely the rated motor supply voltage and the motor stall current. Those specifications should be listed on the motor data sheets.
I would suggest you do some research and look for "Arduino Robots" then expand from there. We are not a free design service but definitely are willing to help you through the process and help with your design as you progress. Motor specifications, voltages, etc are part of your side of the design process as well as choosing hardware and software parts. Explaining why you chose a part will not hurt.
