comment Faulty NXT Motor
Glad to hear you could fix your problem with electrical tape. I doubt that will help this "Faulty NXT Motor", since "very stiff to rotate manually" is an indication of broken gears inside to motor.

comment Teleoperated arm trouble
Are the robotic arm (motor) and the gyro sensor connected to the same EV3 brick? If two EV3 bricks, the programming is more about the communication protocol between the bricks.

comment How do I get the Mindstorm EV3 software to recognize an NXT brick via Bluetooth?
A screenshot of the lower right corner of the EV3 software running on your PC/Mac would help. There is a collapsible panel there that should list EV3/NXT(s) connected. Also, the NXT has to be ON.

comment Code for PID for EV3-g
Not clear whether "I used PID for NXT-G" means you wrote a PID in NXT-G for use on an NXT, or you bought a 3rd party PID control for use with an NXT. Let's assume you want to write the program. A starting point is: e-fisica.fc.up.pt/edicoes/8a-edicao/projectos/… (from a google search for "PID NXT").

comment Is there a time mechanism that can be added to an NXT program?
86400 seconds is a long time for an NXT. I think mine shuts down after ten minutes of inactivity. If it can be set to never shut down, how long do the batteries last?

comment Are NXT Light sensors compatible with EV3?
The question asks "is it as accurate as the EV3 light sensor?" The EV3 has a Color sensor. There are important differences, like the ability to turn on/off the 3 color lights. I'm not editing because the main question is about the Light sensor.

comment How can I remove permanent marker from a LEGO brick?
What color is the marker and the piece of plastic? What type of plastic? Most Lego pieces are ABS plastic, but I think the clear pieces are something else.
