In your code, you set the serial baud-rate to 115200
Code: Select all | TOGGLE FULL SIZE
Serial.begin(115200);

But your serial monitor is set to 9600 (lower right corner)

If you change your serial monitor baud rate to 115200, you should see better results.

hello good morning, you know that my traducccion is not good, but I have problems with my project, first of all I'm basing this project, https://learn.adafruit.com/wifi-controlled-mobile-robot, I am using the components that makes me the picture, I would like if I can provide the connections that I connect them like the diagram says, but I am using the CC3000 shield, not the CC300 breakout, I wonder if they change the connections or what same. I send you some pictures of what I wear, to help me and tell me that is failing me, they are much appreciate, thank you for your attention.

could tell me if there is an error

Here is this by clicking on a button, it is observed that if the data is sent but disconnects the client, and the car does not move forward, be that the connections are not well

The pinouts for the shield are shown in the CC3000 tutorial here: https://learn.adafruit.com/adafruit-cc3 ... onnections
There are some differences from the wiring used for the breakout in the robot tutorial.

good night and check the connections and are well, one of my concerns is that I'm using the shield and engine outputs m1 and m2 are to the engines, I would like to help me with elextronico diagram of all the connections that are used in example you say me, because if you looked at the dainty pictures where supposedly being tested sends the order but the motor does not move, need help with connections https://learn.adafruit.com/wifi-controlled-mobile- robot, I hope your answer thanks
