Smart Lamp Photosensitive

We wanted to present you a smart lamp that based on the light you receive is the regulation of its intensity. The people who did this project are three 3rd year students belonging to the Escuela Técnica Roberto Rocca and our name is Alma Crismanich, Sabina Breska and Lucia De los SANTOS. 

The reason for this lamp is quite easy, to tell the truth, at school we were told that we had to choose a level of difficulty to make a lamp, we chose the basic level since we started to think about what level we were and, to be honest we did not have a good level to go to the highest, that led us to choose that level. The level consisted, as we said, that the intensity varies according to the amount of light it receives.

We also wanted to tell them how we lived it.

First we will tell the part that has to do with the carcasing and then the part that has to do with the operation.

Electronic materials : 

• 7 resistance (220Ω) 
• 6 leds 
• Approximately 45 cables (male-male and female-male)
• 1 Lightfastness 
• 1 Switch 
• 1 Breadboard 
• 1 Battery (9v) 
• 1 arduino UNO 

Materiales carcazado / Carcased materials : 

• Corrugated 
• Easy fibro 
• Jig 
• Carpenter's tail 
• Lamp holder 

First we started with the sketches (to be honest they were not the best sketches). Making a sketch consists of freehand making a simple drawing of what the product would be, in this case, a smart lamp.

In the sketches you can see the shapes of the pieces that are going to be used and how they are joined together, in addition to seeing how many pieces will be used and the shape of the final product. 

Then we made the sketches. Making a sketch is almost the same as making a sketch, with the difference that the sketches already have measurements, are more detailed and have to be done more neatly. 

In the sketches, more lines are usually used than the final ones, with loose and fast strokes, since their purpose is to find the main forms of the product.

In our case we drew the pieces and how the finished lamp would look.

MEASUREMENT: 

Base = Long: 180mm 

Wide: 140mm 

Height: 42mm 

Piece attached to the base = Wide: 65mm 

 Height: 1: 165mm 

Height: 2: 167mm 

 The part that is attached to the lamp holder has the same measurements as the newly named part.

After making the sketches and sketches we did the 3D modeling to buy if the measurements would be correct. When we did the modeling we were good at the measurements so to make it more "formal" we made the manufacturing plans. 

We did the 3D modeling in the Onshape application which at first was difficult for us because we did not know how to use it very well, but once we started we could hold his hand. A 3D modeling is the same as making a sketch, but in digital (more accurately). 

The manufacturing blueprint is much easier to do to tell the truth. The Onshape application has the option to make manufacturing drawings so it made our work much easier. A manufacturing plan is the same as a sketch, except that this is digital and as we said before... It is much more accurate. 

In this part we already pass to real life everything we draw. In our case we made the fibroeasy lamp and joined it with carpenter's glue. 

We made the cuts on each side of each piece and joined them, as I said, with carpenter's glue. Then we decided to paint it so that it is not so simple and give it a touch of who we are. 

The final lamp and how it was painted you will have appreciated it at the top. 

At this time we will begin to tell everything we did to give operation to the lamp. 

First we started with a deep search for what would be the components that we should use to achieve "give life" to the lamp (we put "give life" in quotes because it is a term that is not understood and means that it is to make it walk).   

As you have already seen much above are the components that we will use to operate the lamp so below we will explain what each of them is for: 

• Resistance 220Ω: Electrical resistors are semiconductor components whose main function is to limit the passage of current in an electrical circuit. ... This is a 220 Ω resistor and supports a maximum power of 1/4 W.  
• Led (6): An LED allows the passage of current in only one direction and that when polarized emits a beam of light. 
• Cables: Basically they serve to achieve the connection between the LEDs, the resistors and the battery.   
• Photoresistance: Measures the level of light in which the lamp is located and thus measure the intensity with which the LEDs will illuminate. 
• Switch: used to give the order to turn on or off.  
• Protoboard: It is practically a temporary PCB with a generalized shape and size. Commonly used for temporary circuit testing and prototyping. 
• Battery (9v): used to give energy to what would be the circuit.  
• Arduino ONE: It is a printed board with the necessary components for the microcontroller to work and its communication with a computer through serial communication. 

Once we explained what each component is for, we proceed to say that we did a simulation of the circuit. What we would then have to bring to real life to achieve what our teachers proposed to us.  

After doing the simulation we made a real-life assembly of how each component would be connected. In simple words we made the circuit that was virtual in physical. 

Once we did that we proceed to weld and get it to follow the shape of the lamp.  

In the image above you can see the lamp almost finished.

That's it, thank you very much.
