In this project, we will be making a mini weather station that measures temperature and humidity and transmits them wirelessly to a ground station, which displays the readings on an LCD display!
It’s a fairly easy project and can be used either on its own or part of something bigger.

Anyone awake in the early 2000’s knows the familiar shape of those candy bar style mobile phones. In the Shenzhen phone markets we see tons of them. Literally, there are tons of these phone passing through the markets every day. Some are resold while others are disassembled for parts and recycled. This is where all those cheap Nokia 3310/5110 LCD shields come from. It’s great to see so much reuse and recycling.
Having all these cheap LCDs is nice, but most of the interesting and useful parts are wasted. We saw a fantastic opportunity to save a heap of phones from the recycling bin and save people a pocket full of money. We can make a positive impact on the environment if we reuse some of these phones that we are literally tripping over in the streets. Let’s make an Arduino to GSM network bridge for just a few dollars.

Okay, here’s the deal. There are some tutorials on youtube showing how to get graphics to show on the nokia 5110 and that’s great. If you just want a simple way to do that, go and watch them instead but there are a few problems I see,
1. There are none for mac. I am using a mac and everyone in the videos are using a windows.
2. Sometimes I just wanna go to the computer and search up how to make some graphics. When searching “Nokia 5110 graphics” on google, I found nothing but some libraries and some text.
In this tutorial I will show you how to connect the display, use the code and use some web-based and downloaded tools to create some awesome graphics YOU can customize however you want. Now, enough of me speaking, let’s just begin.

Initial testing. Ignore the humidity sensor, that was for something else.
The vacuum gauge outputs 0-10VDC. This had to be changed to a 0-5VDC range using a potential divider so it was compatible with the Arduino. Initial build used a 10k pot in place of a vacuum gauge to make it simpler.

When you think about Samsung, the first products that come to mind are probably phones or televisions, not Maker-focused electronics. Today, with their announcement at Internet of Things World, Samsung has entered the Maker world with their ARTIK platform, an Arduino compatible family of devices targeted towards Internet of Things applications.
Currently there are three ARTIK devices: The ARTIK 1, ARTIK 5, and ARTIK 10. All are multi-core ARM processors with built in Bluetooth Low Energy. The ARTIK 5 and 10 also include Wi-Fi, BT, Zigbee, and Thread wireless connections.

We are often asked on discussion boards, about conflicts between IRremote or IRLib and other Arduino Libraries. In this post, we present a sketch for ‘Simple Infrared PWM on Arduino’. This is the first part in a 3 part series of posts. Part 1 shows how to generate the simple Infrared carrier frequency on Arduino, using any available IO pin and without conflicting with other libraries. Part 2 will show how to send a RAW infrared signal using this approach and Part 3 will show how to send a common NEC signal from the binary or HEX value.

PyroEDU began in 2012 with the mission of offering free online courses teaching the fundamentals of electrical engineering in an approachable and entertaining manner. Rather than studying textbooks and advanced mathematics, students are taught using a learn-by-doing approach that follows four basic steps: introduce the topic, explain the theory, build an experiment to demonstrate the theory, and offer real-world examples to demonstrate how the topic is utilized today. Students can interact with other students and the instructor via the PyroEDU forums or by joining one of PyroEDU’s hosted classrooms on uReddit or P2PU.
PyroEDU is currently teaching its sixth course, An Introduction to Sensors, covering a wide variety of sensors from motion detectors to temperature sensors. This sixth course is the capstone in the Introductory Series of courses PyroEDU offers (visit http://www.pyroelectro.com/edu/ for a complete listing of courses in the Introductory Series). Working with The Gadgetory, an online electronics retailer, PyroEDU will be offering a comprehensive kit that includes all the parts necessary to complete the Introductory Series of courses. More advanced series are planned in the future which may include courses in animatronics and robotics.
