A Smart House<\/a> will be the next smartphone. The technology that encompasses a smart house will become the new normal for modern-day homeowners. Smart houses range from basic to advanced depending on the sensors that are installed in the house and the operating system. The ARD-02, 201 Arduino Basics Starter Kit<\/a>, comes with everything to build a Smart House Model. The kit comes equipped with a temperature sensor for temperature control, LED lights for the house lighting system, sound for the security system, servo motors, and stepper motors for a wide range of motion control.<\/p>\n\n\n\n

We want to take advantage of the lessons that come with the ARD-02 Kit<\/a>, we will use their provided code and do a little modification to work with the smart house project, I will attach the link for the ARD-02 example code below for reference. <\/p>\n\n\n\n

In today\u2019s project, we will implement the \u201cSensing Light\u201d lesson on page 23, which is the most basic step of a smart house, smart LED light system.
The light sensor will provide constant input from the environment and change the light level accordingly. The light system can be set to a specific mood such as dinner, movie, party, etc.
You can print the house template and glue it on cardboard with school glue, and then cut it out. This project also works with LEGO City Series<\/a> and you would have to run the wire internally within the building.<\/p>\n\n\n\n

\"\"<\/a><\/figure><\/div>\n\n\n\n

Now you need to cut the slot for the door and windows.<\/p>\n\n\n\n

\"\"<\/a><\/figure><\/div>\n\n\n\n

Install the LED lights for the first and second floors.<\/p>\n\n\n\n

\"\"<\/a><\/figure><\/div>\n\n\n\n

For reference, we used glue and a white piece of paper to close up the windows for better light distribution.<\/p>\n\n\n\n

\"\"<\/a><\/figure><\/div>\n\n\n\n

I will include a schematic below for the wiring. <\/p>\n\n\n\n

Assemble and Testing the Light Sensor<\/h5>\n\n\n\n

Required part for assembling the Light Sensor<\/p>\n\n\n\n

\"\"<\/a><\/figure><\/div>\n\n\n\n

I would test the resistor<\/a> value to make sure that you have the correct 10K Ohm.<\/p>\n\n\n\n

\"\"<\/a><\/figure><\/div>\n\n\n\n

I will include the schematic below for reference.<\/p>\n\n\n\n

\"\"<\/a><\/figure><\/div>\n\n\n\n

Finally, connect the 3 wires to the Osepp Uno.<\/p>\n\n\n\n

\"\"<\/a><\/figure><\/div>\n\n\n\n

Upload the code to make sure the Light Sensor work as expected. I will attach a link below where you can download the example file.<\/p>\n\n\n\n

Now, we need to make the sensor portable so that it works with our Smart House project. <\/h5>\n\n\n\n

Solder the one side of the resistor to the photoresistor as the photo below, then solder the wire according to the code. <\/p>\n\n\n\n

\"\"<\/a><\/figure><\/div>\n\n\n\n

The Light Sensor should look like the picture below.<\/p>\n\n\n\n

\"\"<\/a><\/figure><\/div>\n\n\n\n

Pick a location toward the roof of the house for the best light input and connect the wire to the Arduino just like previous step. <\/p>\n\n\n\n

\"\"<\/a><\/figure><\/div>\n\n\n\n

Now we will change the code so that a certain light condition, the LED light system for our smart house will turn on or off accordingly. <\/p>\n\n\n\n
