The bag looks aggressive? Not at all! Let’s do something to add more fun to the aggressive shape. Just think when you touch the spikes, they will retreat just like a snail’s antenna and several minutes later, they will gradually reach out again.
Here is the video.
This may makes us reflect on the relationship between being cool, isolated and more communication with people.
Wanna have your own snail antenna bag? Now it’s making time!
1. Let’s see the theory first
2. Tools and materials
- A spiky bag
- Arduino board
- MPR121 capactive touch breakout
- 12 mini servo motors
- 12 stiff wires
- 12 capacitive touch sensing
- Cardboard paper
- Conduct tape
- Hot melt glue
- needle nose pliers
- electric soldering iron
- First, you will need to solder the headers to the MPR121 shield.
- Next, you will need to add two male header pins to ADDR and IRQ pins on the top of the MPR121 shield. Make sure the long portion the pins are facing up as shown in the picture below.
- Use a female/male jumper cable to connect the MPR121 IRQ pin to digital pin 4.
- Then connect the servo to the Arduino board.
- Glue the stiff wires to the servos and the wires connected to MPR121 shield.
- Stick the conductive tape to the spikes on the inside.
- Fix the servos on the Arduino board and put them into the spiky bag.
