Arduino Uno + L293D Motor Shield + ESP-01

Other Hardware General Electronics

Hi,
Can I use the Arduino Uno board with an L293D motor shield and at the same time use the ESP-01 for wireless communication?

I am planning to solder the wires on top of the L293D shield and connect it to the ESP-01.
Is this feasible?

Thanks

Yes i think it is. You will need to connect the ESP using either hwSerial or swSerial (at a lower baud rate) are you planning to use the AT-commands or will you create custom firmware (the way to go usually). You may even be able to connect the motorshield straight top the ESP. How many pins are in use for the motorshield ?

I would recommend you use something other then the L298, it has a bipolar output and will drop about 3V to the under load. Pick something with MOSFET outputs. If you are planning on using 9V batteries they do not supply enough current.
