Comment on A practical approach to Kalman filter and how to implement it by Lauszus

@kim
No. X, Y and Z simply refer to the axis of the different sensors.

@Winnie
Glad to hear the library is coming to good use

Thank you so much for your work !
It works very well, and it was exactly what I ‘m looking for !
Thank you !

Comment on WiFi Controlled RC Car with the Arduino by Lauszus

@Kakaya_Raznitsa
Just change it from

virtual void write(uint8_t);

To:

virtual size_t write(uint8_t);

In WiServer.h at line 198 and change

void Server::write(uint8_t b) {

To:

size_t Server::write(uint8_t b) {

WiServer.cpp at line 212.

Hi,Lauszus!
I wonder about your power supply for your bot.You use battery as a common source to supply control board and motor or one source for control board and the other for motor ?.thank you?

Comment on RFCOMM/SPP Library for Arduino by the_ether

@Lauszus Thanks for the reply. I don't understand how you can say that Arduinos can't talk together but yet suggest I look at some code that allows them to talk together. But at any rate, since posting this I've discovered Xbee. Zigbee would seem better suited for a mesh network than Bluetooth. Thanks anyway.

@the_ether
At the current time an Arduino can’t talk to another Arduino, but you can connect multiple devices to the Arduino -- see: https://github.com/felis/USB_Host_Shield_2.0/blob/master/examples/Bluetooth/SPPMulti/SPPMulti.ino.

If you want to Arduinos to talk to eachother, then take a look at the following code: https://github.com/felis/Arduino-Bluetooth.

Can Bluetooth be used with one host and several clients that can communicate to the host at the same time? I’d like to build a star network of Arduino devices that communicate wirelessly, using Bluetooth or some other system.

@kim
Simply upload the firmware: https://github.com/TKJElectronics/Balanduino/tree/master/Firmware/Balanduino to your board.
Then download the Processing app: https://github.com/TKJElectronics/BalanduinoProcessingApp then you will be able to see the data on a graph.

@ROY
Check out the firmware for the Balanduino: https://github.com/TKJElectronics/Balanduino/blob/master/Firmware/Balanduino/Balanduino.ino and these I2C routines we wrote: https://github.com/TKJElectronics/Balanduino/blob/master/Firmware/Balanduino/I2C.ino.

Hey,guy!
Cân you tell me how do you calibrate mpu6050 and how do you get the stable angel from mpu6050.It’s better ì you give me your code.Please reply early ! sorry for my disturbing and thank very much.:)
