[font=Helvetica]Hello,[/font]
[font=Helvetica][/font]
[font=Helvetica]I originally bought the AL5DCU-KT and finished constructing everything based on the instructions. Using the instructions from lynxmotion.com/images/html/build185.htm, I matched the jumper setup to the Botboarduino because originally the jumpers were placed in the wrong locations. However, after plugging everything in except for the servo wires and attaching the receiving module from the PS2 v4, the green LED at the end of the receiving module never established a stable connection with the ps2 controller. I don’t know if it is because I plugged something in incorrectly or because the servos weren’t plugged in. I have attached a photo down below. I was wondering if this was the right setup for jumpers. Thank you and I hope to hear from you soon. [/font]

[font=Helvetica]In the image below, I added the blue jumpers because they were shown in the photos from the website but weren’t included in the kit.[/font]

Hi,
First, lets start by correcting a few potential issues and giving you some information about the wiring. See the image below for reference:
From the numbered list in the image (1-5):
]This jumper ties in VL and VS. If you have two different power sources (like you seem to have), you should remove this jumper as it will most likely cause issues./:m]
]These should be set to VS for using with the servomotors. The on-board 5 V regulator cannot provide enough power for the servomotors./:m]
]This is where you will connect the base/shoulder/elbow servomotors (pins 2/3/4). github.com/Lynxmotion/Arms/blob/Botboarduino/PS2_Control/PS2_Control.ino#L42/:m]
]This is where you will connect the wrist/gripper/[wrist rotate] (optional) servomotors (pins 10/11/12). github.com/Lynxmotion/Arms/blob/Botboarduino/PS2_Control/PS2_Control.ino#L45/:m]
]If the yellow-blue-purple cable has the yellow wire going to DAT on the receiver’s adapter board, then it should be all good. Its power jumper should be set to 5V, as you already have done./:m]
Also, you can get quite a bit of information concerning the BotBoarduino here.
As for the receiver itself, if it is powered properly by the BotBoarduino, as soon as the receiver it turns on it will try to connect with it. This should take only a few seconds before the green LED on the receiver turns solid. The blinking state indicates it cannot find the controller. What about the status of the LEDs on the controller itself?
Sincerely,
Thank you for the help. The LEDS on Thebes’s actual ps2 controller are also blinking red and green when it is trying to connect to the receiver. Is this normal?
Hello!
After connecting all of the needed wires and various power sources to my botboarduino v1.0 and connecting the PS2 receiver module, when I try to connect the PS2 controller to the receiver, the red and green lights keep blinking on the PS2 controller and are never able to establish a stable connection. I have tried to wait for a very long time, but nothing seems to work. The lights on the receiver itself also blink periodically. It is almost as though they establish a stable connection for a few second and then lose it and start blinking again until it gets established again. The cycle just keeps going. Is something wrong with the controller? Thank you, and I hope to hear from you soon!
Hi,
It would seem like the controller and receiver are not establishing a connection properly. This may indicate a defective product.
In our last response, we indicated a few things to fix that may interefere with getting a proper PS2 receiver connection. Did you correct all of them?
Please provide us with one or more pictures clearly showing all components (BotBoarduino, wirings, jumpers, power sources, etc.) so we can confirm everything is well setup.
Also, please confirm what power sources you are using for both VS and VL.
Sincerely,
Hi!
I corrected all of the circled items from your first post. I have included pictures of the board and receiver module down below.
As for the power sources, the VS wire that is shown in the first few pictures which I later disconnected was just serving as a backup power source just in case the VL power source didn’t work. So, the VS had no voltage going through it, and the switch was off when I was trying to get the PS2 controller to connect to the receiver. The VL is connected to a 9 volt battery. After connecting everything together including all of the wires from servos, the PS2 controller and receiver module still failed to make a stable connection. It was still blinking. I hope to hear from you soon. Thanks!
Hi,
We notice a few issues with your setup & video.
First, as mentioned previously, the VS=VL jumper needs to be removed.
Also, please note that the VL is meant to only power the on-board electronics (prevent brownout of the microcontroller), not the servomotors. The VS connection is required and should be connected to a stable 6 V DC power source (one is provided with the kit).
The situation you see in your video (the flickering of lights) is most likely due to the board continuously going into reset because of a brownout condition.
Make sure the 5V/VS jumpers in front of the servomotor ports are set to VS so that they get powered by the 6 V DC power supply (the 9 V battery cannot provide enough current for motors).
Sincerely,
