Hey, so I've got to build the circuit to output the signal specified below I've currently got an Arduino UNO and I have written the code to output this. however, I can only put out 5v from my Arduino and the circuit requires 12V and 10V output, being able to switch between12 and 0v incredibly quickly. (the 10v signal is a maximum, this signal needs to be able to be controlled by software). does anyone have details of the hardware required to output this, (an opamp maybe?) a pre-made shield/ shields is preferred but I can create the circuit myself with enough detail in a diagram, thanks.
