151  Using Arduino / Project Guidance / Re: Rebuild a CNC router with Arduino on: November 28, 2012, 04:00:43 pm
I think that it's better to get parts from http://probotix.com/index.php?view=home or similar stores. I had to get parts from Probotix to get an old CNC router working again.

I meant the XBee 5V/3.3V Adapter that I ruined trying to solder the headers on it. The XBee SIP adapter is "plug-and-play" ready instead of a kit.

I found out that a part on the XBee 5V/3.3V Adapter almost came off. I need $28 plus shipping for another XBee SIP adapter.

I don't know why Jeremy Blum didn't use the SoftwareSerial library. I didn't know that I can't use Arduino's Rx and TX pins when the board is connected to USB.

I got the XBee SIP adapter in the mail today. If I connect one XBee to USB adapter and another XBee to SIP adapter with DOUT connected to DIN, and run X-CTU program, both XBees communicate with each other. I searched the Internet for Arduino and XBee tutorials and found one at http://www.jeremyblum.com/2011/02/27/arduino-tutorial-9-wireless-communication/ I found out that I need two XBee adapters. I took the XBee 5V/3.3V adapter and removed extra solder. I couldn't believe it that it worked with the X-CTU communication test. After connecting XBees to Arduino Unos, wiring up a pot to one board and a servo to other board, and uploading the code to the boards, I turned the knob and nothing happened to the servo. If I run the Serial Monitor connected to the board with the pot, I see values change when I turn the knob. If I run the Serial Monitor connected to the board with the servo, I don't see anything on the monitor. The video in the tutorial didn't have captioning. I think that I didn't set up the XBees to communicate with each other. Any suggestions?

I ordered a XBee SIP adapter like this:

The soldering iron's tip was too fat, making me put solder all over the adapter. I don't have soldering iron with skinny tip. I ruined the adapter trying to solder the 0.1" headers to the adapter. The 2mm headers were already soldered on the adapter at the factory. I need 5V/3.3V adapter with all headers already soldered to the adapter at the factory. If the 2mm headers aren't soldered to the adapter at the factory, I would solder the 0.1" headers to the adapter before soldering the 2mm headers to the adapter. The yellow LED doesn't light when I connect 5V and GND wires to the adapter.

I ruined XBee 5V/3.3V Adapter trying to solder headers to it. Any suggestions for assembled adapters? I think that Radio Shack has XBee Shield.
159  Topics / Robotics / Convert angles to microseconds? on: November 17, 2012, 05:53:07 am
How do I convert angles to microseconds? I know that 1000ms = 0 degrees, 1500ms = 90 degrees, and 2000ms = 180 degrees. What about 60 degrees and 120 degrees?
160  Using Arduino / Microcontrollers / Re: Arduino boards with onboard servo and motor controllers? on: November 15, 2012, 09:04:05 pm
I got the Dagu red back spider controller and Dagu Servo Controller Shield for Spider Robot Controller today. There are no instructions on connecting the Dagu Servo Controller Shield to power source and to Dagu red back spider controller. There are two screw terminals marked "IN" and "5V_OUT". I think that the power source is connected to screw terminals marked "IN" and Dagu red back spider controller is connected to screw terminals marked "5V_OUT" but I am not sure. How should the power source be connected to Dagu red back spider controller and Dagu Servo Controller Shield? How should servos be connected to the headers on the Dagu Servo Controller Shield?
161  Using Arduino / Networking, Protocols, and Devices / "Getting Started with XBee RF Modules" tutorial for Arduino? on: November 15, 2012, 04:07:48 pm
There is "Getting Started with XBee RF Modules" tutorial for BASIC Stamp microcontrollers. Is there a similar tutorial for Arduino microcontrollers? I'll be getting the XBee Starter Kit.

I cancelled order for Orion Servo Shield and ordered Dagu red back spider controller.
163  Using Arduino / Motors, Mechanics, and Power / Re: Controlling the parallax standard servo on: November 11, 2012, 06:23:40 pm
Connect the servo's black and red wires to a separate 6V battery (4 1.5V cells). Connect a wire between GND pin on the Arduino and the black wire.
164  Using Arduino / Microcontrollers / Re: Arduino boards with onboard servo and motor controllers? on: November 10, 2012, 07:51:43 pm
I ordered Orion Servo Shield from Basic Micro store. It can control 32 servos and it plugs into Arduino boards.

Am I supposed to use the RCArduinoFastLib with a radio transmitter? My Vex Robotics radio transmitter has RJ10 tether port. How can I connect the radio transmitter to my computer? I ran 12 servos on my Arduino Uno board! Would an Arduino Mega 2560 board run about 40 servos?
