I want to replace a sensor that gives the circuit readings via varying resistance to ground, a high/low resistance that fits within certain values.
Trying not to make a whole new circuit to do this, I already have an output at the right timing on/off that I want, and I will soon get the two resistance levels that I need.
I'm wondering what to use as the "switch" that I have displayed as a transistor in this diagram, the switching signal is 0.619vdc to 0.040vdc. As you can see my attempt at switching between two resistance values to ground is a setup were R1 will be in series to ground (high resistance) and when the "high" from the other circuit kicks in, it will put R2 in parallel and making the resistance level go to a lower resistance to ground.
