HOW TO: Control an Arduino with an iPhone using BLE

This simple example shows a C++/Objective-C program running on desktop, iPhone, and iPad communicating with an Arduino via Bluetooth BLE 4.0 HM-10. Also known as Bluetooth Low Energy. The entire C++ code for communicating with BLE is packed into two small files.

In this example I have boiled away everything except for that code required to open up a serial TX RX pipe to a BLE v4.0 module connected to an Arduino.

The Arduino is a Nano, the BLE v4.0 is an HC-10, and it is controlling a MOSFET FQP30N06L from an iPhone.

The C++ SDK is cocos2d-x but that is not critical to the C++ library in question.

7 Raspberry Pi Substitutes Besides Asus Tinker Board: Speedier, Cheaper, Superb

Raspberry Pi, the debit card-sized PC and the pride of the English persons, has a robust rival coming from yet another coastline – the pride of the Taiwanese persons, Tinker Board. Whilst it has similar enhancements alongside Raspberry Pi, it’s going to be rolled out with stronger technical specs but at a much steeper price as opposed to Pi. On the other hand, the Tinker Board isn’t the only competitor for the most liked micro PC amongst amateurs; turns out, you will find at the very least 7 more.

Less costly Or Speedier Substitutes For Raspberry Pi

Raspberry Pi is the typical go-to single board computer for entertaining programming and practical projects. However , previous to buying one, it can be high-time to take into account its contenders, which are quicker, greater, or maybe more economical, ZD Net claimed.

VoCore 2. This is the new version of Linux and is open-source. It furthermore charges only $15 and is just the thing for projects like constructing tailor-made router or IoT.

C.H.I.P. also, it is quite economical at $9 per piece. It’s the evidence of how cheap computing is currently. It consists of 1.0GHz Processor, 512MB RAM, 4GB Storage area, and has integrated Bluetooth and Wireless network.

Banana Pi M3. It provides 2GB of RAM and offers Octa-core processor. With the ability to work on a wide range of other Operating system that include Ubuntu, Android, Raspbian, and more.

Parallella. It is another visa card-sized computer but depends upon Adapteva’s Epiphany multi-core chips. It is usually utilized three-ways: a stand alone PC, a part in a parallel server cluster, or as being an embedded device.

PixelPro. This features the Freescale i.MX6Q Soc Quad Core ARM Cortex-A9 that runs as high as 1GHz. It’s highly ideal for running multimedia applications of very rich quality with thanks to the 2GB 64-bit DDR3 RAM baked into it. It’s on sale at $129.95 per piece but you will receive a large amount of power for what you are investing in.

Udoo Quad. This $135 PCBA board can run both Android and Linux. Further, it features exactly the same quad-core as Pixel Pro but it is really more and is higher priced too. Still, it will be worth every single penny because of the power it has on the inside.

Arduino INDUSTRIAL 101. This is a $40 PCBA board which you can use either for industrial or commercial. It runs using Atheros AR9331 processor chip and comes with 64MB of RAM.

The Performance Of The Tinker Board

The Tinker Board has specifications that put it face to face versus the ruling Raspberry Pi, The Verge claimed. It possesses a quad-core 1.8GHz ARM Cortex-A17 Processor and 2GB LPDDR3 RAM. Further, it contains four USB 2.0 ports and it gives support for gigabit LAN and Bluetooth 4.0.

Additionally, the Tinker Board contains 3.5mm audio jack, microSD slot, as well as a Micro USB for power source. It can also be swapped with the 802.11 b/g/n Wi-Fi antennas and it carries an HDMI 2.0 port allowing for 4K video.

However , in spite of the 4K support, the Tinker Board is unable to support 4K Netflix streaming, therefore it’s not an excellent option for the people who’re seeking to build up their own unique media center. Even now, it gives owners an better 3D performance and can quickly deal with H.264 or H.265 encoded files.
