Just a quick note for those of you who are interested in the electronics. When setup this way the microphone is powered through the GND and 3V3 pins (via a complete circuit). When the sound around the sensor exceeds a certain level (as determined by the potentiometer, described in the n...
[Lucas] has more plans for his new little buddy, including integrating the original sensors and adding new ones. Given its intended mission, we’d saya lidar sensorwould be a good addition, but that’s just a guess. Whatever he’s got in store for this, we’re keen to hear what happe...
