Recently I bought 2 attiny45 to play around with. I have made myself a simple shield to program the tinys on my UNO and tested a few sketches.
Now. I have an rf 433 transmitter and reciever. The last couple of days i have veen searching for some sample codes explaining how to sent text through the transmitter.
The problem has been that they use some libraries that are too big (more than 4kb) or else i havent been able to make them work.
I have tried RCSwitch (old 4.8kb version), Manchester and Virtualwire..
I want 3 sensor valued transmitted to my arduino by my attiny.
What would be my next approach? Manchester and virtualwire kept giving me errors..
