So now, when we got the cv in- and outputs working it was time to get joystick and potentiometers. We just buyed a cheap Joystick and some 10k Potentiometers. In the first place we were disappointed by the Joystick. The accuracy was extremely low and the spring inside the joystick made it even worse for the usage of accurate voltage generation. So we decided to use 2 channels of the external 16 Bit ADC for the YX-Axis inputs for making the joystick more accurate. And we desoldered the Joystick Circuit, drilled a whole inside and took out the spring. Luckily we orded a 5-Pack of Joysticks instead of just one, because 2 Joysticks got broken in this procedure. The third one was working perfect. | So now, when we got the cv in- and outputs working it was time to get joystick and potentiometers. We just buyed a cheap Joystick and some 10k Potentiometers.

Then we decided to use the whole potential the arduino is giving us with its 6 internal ADC's and connected 4 Knob Potentiometers and 2 Slider Potentiometers to it. These should control different values of our functions on the arduino. | Then we decided to use the whole potential the arduino is giving us with its 6 internal ADC's and connected 4 Knob Potentiometers and 2 Slider Potentiometers to it.

Though we didn't had much functions written yet, we knew we would make different modes. So we got some LED's (1 blue, 3 red) for indicating different modes and also we took a switch button breakout board for changing modes. Another switch button we had available through the joystick itself, because this one had a push function. | Though we didn't had much functions written yet, we knew we would make different modes.

To not get users confused its important to say that these are global modi, which both work in the same way, no matter which of the following (local) modes is chosen. | To not get users confused its important to say that these are global modi, which both work in the same way, no matter which of the following (local) modes is chosen. | ||

The idea of these modes is to mix the voltage generated by the Joystick with different functions. Or, in other words, to make the joystick controlling an offset to different functions. | The idea of these modes is to mix the voltage generated by the Joystick with different functions. Or, in other words, to make the joystick controlling an offset to different functions. Of course, if the Joystick is placed in the left-down corner the offset value is 0 on both axis'. That means if the amount value in any Mode is completely up, the output voltage is completely generated by the function. | ||
