Thanks to Noter's suggestion that I add code to the led_blink program in order to get 5V out on the relevant pin, my led blink project is successfully completed. But I can't get tempsensor to produce a readout on the LCD. The sensor is correctly wired, the LCD works fine, and the program compiles without difficulty. Does this program also need modification? I'm not using the walk through version in the guide-just the untampered with tempsensor program as it downloads from the website.

One of the two versions of "tempsensor.c" needs to be modified (the one located in the "tempsensor_edu" directory I think). The other "should" compile as is. If your temperature sensing chip isn't working or the A/D converter isn't working you should still see a message on the LCD saying something like "ADC: 0 of 1024 Temperature 0 deg F"
