Use this circuit to modulate your Synthkit modules with Brute LFO.

Add wahwah, long sweeps, tremolo, etc. to your projects

How To Make It

STEP 1 : RGB and Light sensor

Place the RGB and Light Sensor bit as seen in the picture. Rotate them so that they keep together ( magnets are attracting each other ) Take measurements and cut out a cardboard light shield. Keep it a bit loose so you can easily move the bits inside the cardboard. With a bit of glue you can keep the cardboard box together, take time to let dry.

STEP 2 : Adjustments

Adjust the 3 colors of the RGB module at MAX. Set the switch of the Light sensor to dark

STEP 3 : Set up your circuit

To understand the principle, build the circuit as seen in the picture

STEP 4 : Install Brute LFO

Install the app and connect the headphone jack of your IOS device to the input of the microphone module with a standard mini jack stereo cable. Play around with the controls and have fun !
