The Pocket Op Amp board brings the op amp inputs and outputs to a prototyping area on the board. These pins correspond to Arduino pins 13 to 19, excluding 18 which is the DAC. They can all be used for digital I/O and for analogue input, and 13 to 17 can be used for PWM ...
Notice that the voltage gain of the circuit does not depend on the gain of the op amp. We are assuming that if the op amp gain isreally big, then enough feedback will be applied to the non-inverting input to produce the desired function. Let us check that assumption about the two op...

The voltage control PWM could be generated by first using the triangle signal generator which provide the basic PWM pulse frequency and the necessary ramp voltage (rise and down) to produce the PWM signal. Next by continuously comparing this ramp voltage according to the voltage level produced by...
If the op amp is configured with a voltage gain of 2, the 1.5V regulator in combina- tion with the op amp behaves as an adjustable output regulator with a 0.75V reference voltage. The input to the op amp now serves as the ADJ input of the new regulator. This technique allows the ...
