Right-Angle Socket Header
To keep the build slim, we used a right-angled Socket header pins to connect the continuous servo motor.
Slide Switch
Using a short length of ribbon wire, solder one of the slide switch's outer legs to the EN pin and center leg to the GND pin on the Feather.
Mount Feather
Align the Rod-Holder part to the screw mounts on the Feather.
Use M2.5x12mm screws to fasten the Rod-Holder and Feather to the Body-Mount part.
Mount Slide Switch
Place the slide switch inside the cut-out on the Body-Mount part.
Connect Transducer wires
Solder wires to the Transducer. Use the terminal block to connect wires. Tuck the wires under the Feather
Lipo Holder
Use M2x8mm long screws to fasten the Lipo-Holder part to the Body-Servo Part.
Insert a 2200mAh lipo battery into the Lipo-Holder.
Mount Servo
Use the included servo screws or a M2x8mm screw, to secure to the Body-Servo part. Attach a double arm servo horn with the included screws.
Mount Transducer
Press fit the Transducer to the bottom Body-Servo part.
Assemble Rod
The Rod on Top-Body part slides into the Rod-Holder part.
The Stopper part is fastened with a M2.5x8mm screw.
Use a small amount of lube to reduce friction on the rod.
We used Ardent Reel Butter Bearing Lube.
Align body parts
Connect the Servo and Lipo battery to the ports on the Feather.
Thread wires away from the servo horn and the body side edges.
Use M2x8mm screws to join the bodies together.
Use
In the code, whenever the accelerometer detects the device is being shaked, it’ll drive the continuous servo and play the sound effect through the I2S audio amplifier.
The servo actuates the top clapper repeatedly while the transducer turns the surface into a speaker and plays the thumper sound effect.
We think this demo code could be used in other projects, just change up the accelerometer's sensitivity and timing of the servo to fit your project.
