I recently began the water tank sensor experiment showcased in chapter 12. I have done some basic Arduino and sensor assembly, but the addition of the op-amp has proven more challenging than anticipated.
So far, the figures 12-3 and 12-4 do a pretty good job showing the assembly on the protoshield, but it would be great to have a view of the traces as well.
Any help would be much appreciated!
The book "Practical Arduino" by Jonathan Oxer and Hugh Blemings covers a range of projects and techniques from basic to advanced. [Book site] [Buy online]
