Simply send us a message through our Customer Support Center indicating your invoice number and requesting an exchange for the DFRobotShop Rover Main Board. You can also include a link to this forum thread so we can quickly determine the nature and origin of the message. We will then send you an RMA number so you can proceed with the exchange.
That is rather strange.
Especially since pin 13 is flashing. Maybe there is a short-circuit somewhere. Are you sure you are jumping the correct pins. We have reproduced your setup and everything seems to work just fine (i.e. the motors turn when the jumper is in).
Maybe you charger is malfunctioning. Could you please measure its outputs and let us know what are the values (i.e. is it providing 5V?)
Even under optimal sunlight condition, we believe the current won’t be enough to power the motors directly. It might be able to make them spin a little but the current would be too low.
EdZilla,
That is very strange. The LEDs should be independent of the motors. Is the LED jumper in place (right next to the switch). Also, if we understand correctly, the LEDs do turn on when connected to the USB.
If this is the case, then you might have a defective power regulation / step-up circuit. Could you confirm this is the case?
We are working on the video ans should be posting it shortly. You got the procedure right but we believe that maybe you did not load the right program. It seems as if you have the blink example loaded.
Please make sure the sample program provided in the manual is the one loaded.
EdZilla,
We measured the voltage and indeed there is a transient dropout but the voltage rises quickly up top 5V again. This is basically caused by the change in load but it should last less than a second.
Low means OFF for the H-bridge. Thus, the motors should not be consuming power when the robot stays immobile.
Merry Christmas to you too!
@ dias, any plan on sharing the code for the WiShield. Your application is awesome and could certainly still be useful for everybody trying to do WiFi Robots!
Thanks for sharing!
In order to make sure your Bluetooth module is connected and working fine, you might want to make a loopback test by shorting its RX and TX pins. In your console, you should get an echo that will prove you are actually sending and receiving data.
Using the USB cable to upload a sketch while the Bluetooth module is plugged-in might not work since they both share the same serial lines.
Also, it is always good to double check the same baud-rate is being used everywhere.
