Arduino project

Former Member

i saw a project in which the person made a wireless hand controlled robotic hand using 5 servos.(similar to what i am trying to achieve)

in that he uses 2 X bees and connects them to the 2 arduinos. Then in the program he just writes Serial.begin(9600);in transmitter, and Serial.read in reciever, and that's it . Rest of the program is just for the servo control. How does this work .

 

I am still not able to figure out how x-bee is working . is it just creating a serial comm between arduinos , just like between pc and single arduino via USB???

link to that project -How to make a remote controlled Robotic Hand with Arduino - All

code he has used

  • Hello, by a hardware point of view I see that there are two x-bee units that grant the communication between the two arduino boards. There is the discussion about the use of the PC that is a bit confusing, but it is just the programming side of the project.

     

    Your observation is true, to a first look it seems that x-bee connection is not mentioned at all. The same if you look to the test communication program. As a matter of fact it is correct. Accordingly with the x-bee for Arduino connection specifications and behaviour you find on Arduino - ArduinoXbeeShield you read in one of the first paragraphs:

     

    The module can communicate up to 100 feet indoors or 300 feet outdoors (with line-of-sight). It can be used as a serial/usb replacement or you can put it into a command mode and configure it for a variety of broadcast and mesh networking options.

     

    So, in a basic usage of the module (that is how this project uses it) you don't need to do nothing more than working with the serial connection that will be replaced by the wireless communication. The two resistors small breadboarded circuit where the X-Bee module is soldered in this Instructable project as a matter of fact replace at lower cost with a hand-made version the x-bee shield mentioned in the link above.
