November 14, 2010 by RSW	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.
November 14, 2010 by RSW	Figured it out: send the numerical value as a string, followed by "\n".
November 15, 2010 by hevans (NerdKits Staff)	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. Humberto
