Everything Else » Sending decimal values through PySerial

Hello, I was experimenting with PySerial and I noticed that the write( ) function can only send strings. Is there any way to send number (int, float, etc.) values to my nerdkit? Thanks.

Figured it out: send the numerical value as a string, followed by "\n".

Hi RSW,

Glad you figured it out. In case someone stumbles on this thread with the same question, the answer is indeed to send the value as a string. On the MCU side you can use one of the scanf family of functions to read the value into a variable. Check out the print and scanf tutorial for more on those functions.
