Hello,
I have a troubleshooting problem with my A4WD1 PS2 Controlled Rover. The issue is that after following the tutorials provided, placing jumpers in correct spots, and coding the given code there seems to be a problem with the communication between the PS2 controller and the receiver. I have ruled out all other possibilities due to the rover following both test codes which check to make sure it is operating correctly. I have switched out receivers and controllers several times with others and they too do not seem to work.
The communication issue appears to be between the PS2 Receiver and controller because no matter how long they are both on or if we turn one of and back on they do not synch up and communicate. I have tried everything I could think of. I have tried both old receivers and the newer version with the level shifter. Neither version has been able to communicate with the rover. Any possible solutions would be much appreciated.
As a result my satisfaction with this rover is diminishing greatly….
Thanks for looking,

Can you post an image of the PS2, receiver and connection to the board? The RC-01V2 with level shifter should work assuming you have all 6 wires connected correctly. Turn the robot on first, then the controller. The light on the left side of the receiver should become solid (stop blinking) when the transmitter is turned on. In case it’s not the controller which is the issue, can you also include a clear image of the connections on the microcontroller board as well? Last, include a link to the code you are using.
Here is the link to the program that we are using:

Here are pictures of the V1 PS2 Controller and Reciever:

You are using the old PS2 controller with the old cable - so the two should be compatible.
The VL=VS jumper is in place - but it’s hard to see if you have power going to each of the screw terminals and what the voltage is for each?
Is the jumper associated with pins 12 to 15 in place? I see it’s missing for pins 8 to 11. If the jumper is not in place, then the receive will not be getting proper power.
Last, is to triple check the PS2 connections and ensure they correspond with the sample code.
After trying all 3 of your items listed we got the same exactly result… Solid green light and flashing red light on our receiver. And a blinking red light on the controller. Any other suggestions?
Thanks,

Can you include an updated photo of the bot board 2 clearly showing the jumpers and connections?
We also note that your VL=VS jumper is in place, but how are you powering VL? If you are only using the 4.8V to 6V servo supply, it’s important to note that VL requires about 9V (we suggest a 9V battery). It could be that “the lights are on but nobody’s home”.
