What apps do I use more in my smartphone?

Hi again!
I wanted to do a "trending topic" that many people is doing and is: WHAT APPS DO I  USE MORE IN MY SMARTPHONE?
First of all I have to say that my phone is an LG G2 and I am very happy with it, for me is perfect.
Let's start!
-Pixel Battery Saver:
A very useful app to save battery that, basically, turns off a cuantity of pixels of your screen, it is very useful for moments where you need to use your phone but without wasting so much battery.
-My Data Manager:
I think it is the best app to control your data plan, it shows data, wifi and roaming and estimates how many MB are you going to use. You can also program alarms.
-Strava & Runtastic Mountain Bike:
Very good apps for those that ride their bikes to make routes and control haw many kilometers have you made, I use them every time I go with my bike.
-Aliexpress:
I am a fan of shopping in China, although it takes a month to arrive, the objects are very cheap and I think that Aliexpress is the cheapest market.
-Splive Player:
The best for watching TV on your phone or tablet, it includes public and private TV!! Totally recommended!
I have to say that it is not on the Play Store so you will need to download it from internet.

Those are the most usefull apps that I have appart from WhatsApp, Facebook and soon...
I think it is OK for today, so have a nice day!!

LDR Project

The aim of this project was to create a circuit with an LDR and a Par Darlingtong that changes the active component between night and day.
My friend and me decided to make a heliport which, during the night turns the lights on and during the day turns the lights off.
I think the project was good, simple but well done. The teacher decided to give us a 10.
There you have a photo, a video of the project and the summary: 

-SUMMARY-(LDR PROJECT)-

-Objective:

The objective is to make a circuit using an LDR and a relay, by which a motor, led… etc. that works during day and does not during night.

-How does it work?

The LDR allows electricity to pass when there is light; it activates the “Par Darlington” and excites the relay so that the LEDs get off.

-Materials:

We have used LEDs, an LDR, a relay, a 5v power supply, a 10K potentiometer, two transistors, a resistance, wires, a tupper and wood.

-Building process:

1^st we made the circuit on a plate of wood and checked it.

2^nd we painted the tupper and the “H” on the wood.

3^rd we have built the project assembling the parts.

-Conclusion:

We have enjoyed this project because is the first time we make a project using an LDR and transistors and a relay and we have liked it because it is like an “automatic” project.

-Circuit:

Welcome!!

Hi people,
Welcome to my new blog where I will write about projects and works of the Technology class.
in the next days I will write about the latest work that I have made: An LDR circuit...
