Class: Technology, Arduino

 

Hardware:

  • Arduino Uno
  • Breadboard Circuit
  • Jumper Wires
  • DHT11 sensor x 1
  • Mini Servo Motor x 2

 

Software:

  • Arduino

 

Task:

The idea was to program servo motors to rotate according to humidity and temperature as an input. I used two servo motors and DHT 11 sensor. When temperature gets higher than 26c, servos start rotating for 180, when the temperature goes down, they rotate back.

Assembly:

I prepared all the components. After I began to wire them, actually it took much time, because I didn’t know how how to do that. I started searching on www.instructables.com for similar projects, i found some and began to create the code. When I finished it all worked well, servos were rotating according to the temperature and humidity. I was really proud of myself. You can check my code at the end of the post.

City Project / Things

Materials used
  • copper wire 0.5 mm
  • 1 led lightbulb
  • cardboard tube 160 x 17 mm
  • 6 magnets 15 x 5 mm
Idea

To create device that transforms the kinetic energy from your motion into power and stores it. We are going to use inductor technology that enables the device to generate significant power while remaining compact. The idea is that movement shakes internal magnets which generate current that can be then stored and used.

Process

Our first aim was to understand how induction works. We decided to make a tube covered with copper coil connected to the lightbulb and to put inside the tube magnets. The result that we wanted to see – was blinking lightbulb.



 This image shows pieces that we used to create our prototype.

 


We had some problems with soldering copper wire to the lightbulb but soon we are going to improve our skills 🙂



This video shows how induction works.
