I have recently bought the Lynxmotion AL5D arm with the Botboarduino/PS2 board and i cannot get it to respond. i followed the instructions on the Lynxmotion page and was able to download the PS2X control software onto the board but the Lynxmotion controller wont connect and when i bring up the terminal it says that it was not able to find the controller. if i try to turn it on it jerks to the right and down. Any help would be appreciated
We will be posting a solution to the issue shortly. The RC-01 V2 does not work with the old PS2 cable.
Unfortunately, the latest version of the PS2 controllers are not compatible with 5V TTL logic directly. In order to work with them, you will need to use a level shifter lynxmotion.com/p-870-ps2-wireless-controller-receiver-level-shifter.aspx.
Please note the controller sold at Lynxmotion includes the level shifter and that the PS2 direct cable is being phased out.
Please see below a diagram on how to connect the level shifter:

Also if you look at the picture by Carlos, you can see this is easy with 2 servo extension cables. Take the first one and in his picture plug it into the first three pins on the adapter (I would normally put the black wire where the white one is shown in the picture and then plug it into IO pins of botboarduino (6-8). Take 2nd cable and plug in to the other three pins, with the wires matching the colors shown in diagram (ie black to ground pin), and then simply plug the other end onto pin 9 of botboarduino with black going to ground, yellow going to signal.
As always for the DIY’s you can find out more information about PS2 signals up on: billporter.info/2011/03/27/a … ing-guide/
In here there is discussions on how to adapt a 3.3v PS2 controller to a 5v computer… In particular some have had success with adding resistors in the wires between the microcontroller and the PS2. From his document:
5V = 180 ohm, voltage drop of 1.85V (3.15v to the controller)
ATT = 5.6K ohm, voltage drop of 1.08V (3.92 to the controller)
CLK = 5.6K ohm, voltage drop of 1.15V (3.85 to the controller)
CMD = 860K ohm, voltage drop of 1.39V (3.61 to the controller)
