Modify your voice by experimenting with the Microphone and the Synth Kit. Add echo and feedback with the delay and change the sound’s character with the filter.
Start by building the circuit: power + split + microphone + wire + filter + delay + wire + speaker. To the other side of the split, add an rgb led.
Test out the circuit. When you speak into the microphone and turn up the feedback, you should here your voice start to echo. Adjusting the time will make your voice sound low and deep or high and fast depending on which direction you turn the knob. Make sure to adjust the filter as well - it is a little tricky. Make sure the cutoff is in the middle range and peak is not too high.The Synth Speaker was not as loud as we wanted it to be for this project so we plugged external speakers into the output jack. This helps to get a much louder and dynamic voice changing sound.
Make a base structure for your microphone. We used the top of a round metal box. We drilled holes in the base for the knobs on the Filter and Delay, a small hole for the Synth Speaker wire to pass through, as well as a hole to secure the neck of the loudspeaker.Note: Be careful when working with littleBits and Metal. The modules should never touch metal, as this will cause them to short. If you do work with metal, make sure to encase the modules in such a way that they can’t touch the metal surface.
