I need to connect an analog sensor to the robot controller which sends currents of up to 2.4V in both ways. I mean, there are two wires. In one state both carry no current, in another one carries 2.4V and in the third it is the other wire wich carries 2.4V. Do you have an idea how I could solve this problem? Are the analog inputs able to read negative voltage?
Would it be possible split both wires and connect them to two analog inputs with one cable on the signal at one port and the other cable at the secound port (loose cable in both cases to ground)? Would it demage the controller if in this way 2.4V are also connected to the ground pin at one port? Are all ground pins directly connected?
Not sure what exactly you are trying to do, but hopefully this will help. Analog Inputs can not read negative voltages. You can connect your 2 output signal wires from your device to 2 different Analog Inputs. You must also connect a ground from your device to the ground on the Robot Controller. All ground pins on the Robot Controller are connected together. You will now have to modify your code to read these 2 Analog Inputs. You will be able to see changes on the Analog Inputs from about 0 to 5 volts.
