I have successfuly connect my HC-05 bluetooth module to pyboard via UART(6). I also have tried to connect and send serial data from computer. Now I currently trying to receive data from Bluetooth Serial Controller Android app to pyboard. The app can connect to bluetooth module and I try to send char...

I am using ULD2003 and trying the code from @riklaunim. It works but the rotation is too slow, even after I change the delay to 2ms. How can I raise the speed?

Wow, nice information. I first thought that the only way we can connect the board from web is using Wifi.
I will try it to this project. Thanks, Dave!

Ok, I get it now. Thanks

I still rather confuse of what pin connect to what pin on pyboard. The pin sequence on i2c lcd board (from top to bottom) is GND, VCC, SDA, SCL. On pyboard, SDA is X10 and SCL is X9. Do we need to cross SDA-SCL from lcd to pyboard, or SDA to SDA and SCL to SCL? Because I see in UART that TX go to RX...

Ah, I found this in micropython wiki https://github.com/micropython/micropyt ... rduino-Due
But porting hasn't yet been done for this board..

Is there any way to run micropython on Arduino board? Which Arduino Board that can run Micropython and how to do it?

Ah, one more thing. I tried to add pyb.usb_mode('VCP') and then write the code to main.py via REPL like above. But when I go to safe mode to open mass storage, the file isn't in utf8 format or in other words, the file can't be opened. http://i.imgur.com/kIAOUMP.png How we set the file to UTF-8 forma...

Thank you very much, as always

I run this code on REPL: >>> import os >>> f = open('/flash/main.py', 'w') >>> f.write('while True:\n') 12 >>> f.write(' pyb.LED(3).toggle()\n') 22 >>> f.write(' pyb.delay(1000)\n') 18 >>> f.close() >>> os.sync() and the code run successfuly after I press Ctrl + D. But if I check the main.py via mas...
