* Question 1Q: What will the voltage at A_IN be? What are the upper and lower values? * Question 2Q: Looking at the Arduino help for the <code>analogRead()</code> function, what will the value <code>val</code> be for those highest and lowest voltages? * photoresistor from your 147A kit... 160k - ~10k (depending on your lighting conditions).* Q: With the same 10k resistor from the schematic above, what range of voltages (and corresponding data values) would you expect to see with this?* Q: How could we verify this?
* strain gauge
