This Non inverting amplifier circuit demonstrates the principle of working of opamp as non inverting amplifier. This project also uses the concept of negative feedback. The input voltage is given at positive pin of opamp while its negative pin is connected to resistors
R1 and R2. R1 is connected to ground and R2 is connected to Vout.
The amplification takes place according to the formula:
Amplification factor = [1+ (R1/R2)]
