You can use other sensors like LDR or NTC instead of the copper ones so you can use this circuit for detecting light or temperature. I love all about electronics, circuit diagrams and crazy projects ...

are clear, simple diagrams showing all of the input, process and output elements that make up the system being designed. They are easy to read and show how the circuit will work. Circuit diagrams ...
