I am about to totally give up. I have yet to download a sketch that works anywhere for any of the things I bought. Why is this so difficult? Why can't I just load a sketch and have it work? DHT11 sensor does't work. HR501 RIf sensor can't make it work, have tried every sketch I can find.
This is too general. I find most stuff works. Sometimes (due to the rate of change) you need to update libraries/sketches to match current developments. Or, downgrade the IDE.
Start with a specific sketch, post it, describe the hardware, show any error messages, show what you expect and what actually happens.How to use this forum
