I am a middle school teacher building the SkyWeather 2 weather station with my 8th grade and I have never done any coding before (talk about jumping right in!) We have successfully connected our Raspberry Pi to the wireless network and are now trying to test the reception of the wireless weather sensors. When I follow the directions and put in the code for the testing, I get the error below. We have built the WeatherRack2 system (main weather station and indoor temperature humidity sensor). Can anybody help us get past this issue? We have purchased the SD card from Switch Doc since we are newbies at coding!
