Arduino + Android Projects for the Evil Genius: Control Arduino with Your Smartphone or Tablet

By Simon Monk


Filled with useful, selfmade instruments, Arduino + Android tasks for the Evil Genius exhibits you ways to create Arduino units and keep an eye on them with Android smartphones and capsules. Easy-to-find apparatus and elements are used for the entire initiatives within the book.

This wickedly creative advisor covers the Android Open software improvement equipment (ADK) and USB interface and explains how you can use them with the fundamental Arduino platform. equipment of communique among Android and Arduino that do not require the ADK--including sound, Bluetooth, and WiFi/Ethernet also are mentioned. An Arduino ADK programming educational is helping you start correct away.

Arduino + Android initiatives for the Evil Genius:

  • Contains step by step directions and beneficial illustrations
  • Provides guidance for customizing the initiatives
  • Covers the underlying rules in the back of the tasks
  • Removes the disappointment factor--all required elements are indexed
  • Provides all resource code at the book's website

Build those and different devious devices:

  • Bluetooth robotic
  • Android Geiger counter
  • Android-controlled mild express
  • TV distant
  • Temperature logger
  • Ultrasonic variety finder
  • Home automation controller
  • Remote strength and lighting fixtures keep an eye on
  • Smart thermostat
  • RFID door lock
  • Signaling flags
  • Delay timer

That's, it's the Arduino that's in command of the location because the USB host. It needs to start up the relationship with the Android mobile. whilst it does so, it will probably additionally set off the telephone to instantly change into accent mode and open a customized app. accordingly, it's going to open the DroidGeiger app we have now constructed for this undertaking. The Arduino can be required to supply charging energy to the telephone. So any accent we construct utilizing our Arduino has to be in a position to delivering as much as 500mA at 5V over USB to cost the telephone. which means the accent both has to be powered from an influence adapter, or when it comes to this undertaking, powered from a good battery. Later during this bankruptcy, we additionally examine find out how to get round this challenge and use a noncharging lead for the relationship. building just like the robotic of the former bankruptcy, this venture makes use of a safeguard connected to the head of the Arduino Uno. as a consequence, the safeguard is a USB host defend. you can be pondering that this can be pointless as the Arduino has a USB connector. regrettably, the USB connection at the Arduino itself is a USB buyer connection, and to hook up with an Android mobilephone we'd like a USB host connection. in reality, the USB host guard has a convenient prototyping sector to which we will solder the opposite elements wanted for the undertaking. The schematic diagram for the undertaking is proven in determine 2-3. determine 2-3 The schematic diagram the most goal of the circuit is to generate the 400V wanted by means of the GM tube. you will find a extra targeted description of the way this circuit works within the “Theory” part on the finish of this bankruptcy. What you'll want as well as an accessory-capable Android telephone (Android 2. three. four or later), you'll want the parts indexed within the following elements Bin to make the sound hyperlink module. should you plan to make the noncharging USB lead, you will want 1kΩ resistors instead of only one. additionally, you will want an previous USB extension lead. For a longer-lasting battery substitute, use a holder that might settle for six AA cells to provide the venture with 9V. This replacement is proven in the various figures. the most important part for this venture is the GM tube. those will be simply discovered on eBay from overseas dealers, usually from former Soviet Union nations. The tube that the writer defined is a “Russian army GEIGER TUBE COUNTER CI-1. ” The tube has the subsequent requirements. notwithstanding, different related units may still paintings simply wonderful. Our Geiger counter isn't for serious events. it's going to now not be calibrated, so accuracy is just not a attention. variety: Gamma detector 360–440V anode voltage Plateau size: 80V Inclination: zero. 125%/V Load resistance: 10MΩ size: 90mm Diameter: 12mm we are going to see later how one can modify the anode voltage we generate utilizing the Arduino caricature among zero and 450V, the restrict for our capacitors. This layout employs the Arduino Uno. The professional Arduino website (www. arduino. cc) lists providers of the Uno. in spite of the fact that, when you are on the cheap, you should use an Arduino identical to the Arduino Uno.
