Question:I have a lynxmotion robot, and I want to make it talk to a machine connected to a VEX Cortex using inputs and outputs. How do I do this?
Answer:This is called handshaking, and you will need at least one computer, Flowarm and RobotC Software, a Lynx arm with SSC32 controller, and a VEX cortex to do this. Below is a worksheet that you can download with all of the basics, and there will be a video below shortly as well. VEX 2 Lynx Handshaking Continue Reading
Question:I have two lynxmotion robots, and I want to make them talk to one another via inputs and outputs. How do I do this?
Answer:You will need two robot arms using SSC32U controllers, a few 4N25 optical isolators a few resistors, FlowArm software and some wires and a breadboard and you are ready to go! Below is a worksheet that you can download with all of the basics, and there will be a video below shortly as well. SSC32U to SSC32U Handshaking Continue Reading

Soldering Diagram (Better one coming soon!)
- Solder 4N25 IC’s in place. Use caution and work quickly as they are heat sensitive.
- Solder LED’s and Headers in place (or wires, your choice!)
- Knock the corners of the board off so it fits into the container.
- Snap the board into the container.
- Place the spacers on top of the board.
- Place the cover on carefully.
- Put the 4-40 screws through.
- Put the nuts on the back, tighten carefully.
Tips and Tricks:
|Paint the cover BLACK before you peel it, and the black dots will indicate where the black wires go! The arrows indicate the direction of the communication: Tail of the arrow = the signal “Sender”, head of the arrow = signal “Receiver”|
|Container back prints with space for 4-40 nuts.||Container front prints so that the board will snap into the built in standoffs. IN ORDER TO FIT, YOU HAVE TO KNOCK THE CORNERS OFF THE BREADBOARD. I used a belt sander.|
|To assemble the parts, see below. Be sure to use the printed spacers to stop the board from wiggling around!|
