Step 1: Tools and Materials
LCD Keypad shield
Ultrasound distance sensor
wood with the same size that the bag has
Step 2: Put the Arduino Into the Bag
We will put framing squares to fix the bracket in the bicycle's box. We have to remember to make enough place for wire-cables.
Step 3: Put the Sensors
We will put this sensor under the seat. All the bicycle's seats have the same structure. They have 2 metal bars. We can use wire to fix this sensor. The wire has to allow the sensors' movements, because in case you fall with the bicycle the gadget will not be damaged. Don't worry about this position because this type of sensor have a wide angle.
It detects if someone moves the bicycle. Depending on where it is placed, the movements can been modified in different level. The best place is the handlebars. We will hide this sensor inside the bar of the handlebars. If you want to instal it permanently maybe you should do a small hole with the drill on the handlebars.
We will fix the sensor on the stem (supporter of the handlebars), and you can do it in differents ways. One of the most easy way is to use a plastic tube. You make a vertical cut and 2 big holes for the sensor. And then you can use a lot of things to fix it to the bicycle.
Step 4: Plug In
The code's annotations are made in Catalan. If someone needs to read the annotations, he can ask someone who speaks Spanish, becouse both languages are very similar.
