What are Hackable ports?


Hackable ports are ports that allow you to hack into the UnlimitedHand.

UnlimitedHand has a total of 2 Hackable ports.
With USB microB interface port being one of them,
we now introduce the other secret one, the ICSP port.
In fact, it has been kept a secret up till now.


What can you do with ICSP port?
There are 3 main uses for the ICSP port:
· SPI communication (connect with external hardware / devices)
· Expansion of input / output pins
· Boot-loading


CAUTION: Hacking through ICSP port may damage your device. Use it at your own risk.
In next section, we introduce tutorials for the ICSP port.

Blinking LED
In this tutorial we will blink an LED with the UnlimitedHand.


CAUTION: Hacking through ICSP port may damage your device. Use it at your own risk.

STEP 1. What you will need

1x UnlimitedHand
1x USB micro B-A cable (included in the UnlimitedHand Package)
1x Breadboard
1x LED
1x Resistor(values ranging from 300 Ω to 2KΩ will do for a 5V power supply)
2x Jumper Wires




STEP 2. Hardware Hookup

Connect D11 and GND on the device out to a breadboard with jumper wires.

Check out the Fritzing diagram below. 
Connect a LED and a resistor to the breadboard accordingly.

     




STEP 3. Writing of program

Open a new Arduino sketch, paste in the sample sketch below and save your sketch.

sample sketch<UnlimitedHandBlink>
/*
  Blink
  Turns on an LED on for one second, then off for one second, repeatedly.
 */


// the setup function runs once when you press reset or power the board
void setup() {
// initialize digital pin 11 as an output.
  pinMode(11, OUTPUT);
}

// the loop function runs over and over again forever
void loop() {
  digitalWrite(11, HIGH);   
// turn the LED on (HIGH is the voltage level)
  delay(1000);             
// wait for a second
  digitalWrite(11, LOW);   
// turn the LED off by making the voltage LOW
  delay(1000);             
// wait for a second
}

Save the sketch.


Connect UnlimitedHand to your PC with the USB microB-A cable provided.
Press once on the power button to switch on the device.


Set the serial port on Arduino IDE.
"Tools" -> "Port" (/dev/cu/-* on Mac, COM* on Windows)


Push upload button on Arduino IDE to upload the sketch to the device.


Make sure that the sketch is uploaded successfully, and the LED in your circuit will begin blinking.

Introduction



This tutorial runs you through how we can control an LED's blinking pattern.
This time we will show how you can apply it on UnlimitedHand to build a gesture controlled remote control.


How a remote works


Infrared is not visible to the naked eye, when a button is pressed on a remote an infrared LED on the device flashes in a very high frequency. Home appliances often receive these signals as commands that trigger various functions. Signals received may be used to control a television’s volume, channel and switching it on or off.


How can we use the UnlimitedHand?


UnlimitedHand is licensed as an AtHeart project by Arduino. This means that it’s micro-computer can be used in the same way as a Arduino board. The pins VCC, GND, TST, D11, D12, D13 can be used. UnlimitedHand’s ICSP port can be used as if programming Arduino’s DIGITAL pins with the functions digitalWrite() and delayMicroseconds(). By doing so we can control the blinking patterns of the infrared LED to create a remote with the Arduino licensed device.



1. Preparation

  • - UnlimitedHand and USB cable
  • - Infrared LED (TLN110(F))
  • - Pin Header (2mm)
  • - Shielded copper wires
  • - Resistor (47 Ohm)


2. Schematic

In this tutorial we will be following the schematic below.



3. Attaching the LED sockets


To complete the circuit, we will use a soldering iron to create the LED socket as shown by the image below.

Connect the socket to UnlimitedHand’s GND and D11 pins. Plug the LED into the terminal. Beware that the LED is polarized, make sure it is connected in the correct direction.




4. Installing the Library

We will need to update the program within the UnlimitedHand to complete this project.
Download Arduino's UnlimitedHand Library
We will explain how to install and use the library here.



5. Compiling the Program


Connect Unlimited to your computer, use Arduino IDE to compile the program. To select the program, click File > Examples > UH > remoteControl. This program allows you to switch on/off AQUOS televisions made by SHARP.



6. Operation Test


Once you are done with compiling the program, please follow the steps below.

  • 1. Since infrared rays are not visible to the eye, use a red LED in place.
  • 2. Strap on the UnlimitedHand, make a fist and open up your palm repeatedly to check if the red LED blinks according to the change of your gesture.
  • 3. Replace the the red LED with an infraredLED, point your hand at the television.
  • 4. If you hold a fist and see the television turn on, you have succeeded.




7. Further Reading

You could use the program in previous tutorial [blinking LED] to create blinking infrared patterns that are able to control home appliances. Combined with the [remoteReceiver] tutorial, you will be able to create programs that work both ways. With UnlimitedHand’s accelerometer and gyroscope, you can tweak the device to enter receiving mode when your arms are let down, and enter transmission mode when your arms are raised. Various gestural applications can be realized if you are willing to take up the challenge.

Introduction

This page guides you through making a remote for controlling a television with gestures.
This tutorial will teach you how to control the television with gestures using UnlimitedHand’s ICSP port.
This time we will use sensors to collect data from our environment.

We will demonstrate how the device is capable of reading IR signals transmitted by a remote controller.


Creating a gesture remote with the UnlimitedHand

Various sensors used to create a gesture-based remote with UnlimitedHand

Sensors are a general term for components that take in information from our environment. Temperature sensors, light sensors, humidity sensors, acceleration sensors, are some of the various sensors that we can put to use. In this tutorial, we will be using infrared sensors typically embedded in television sets and air-conditioners to receive signals from remotes. We will be able to sense blinking patterns emitted by infrared devices, which are not visible to the naked eye.

Infrared sensors are available for sale as various modules.
You can look for them in stores that sell electronic components.


Various types of infrared signal receivers

Realizing it on the UnlimitedHand

UnlimitedHand is licensed as an AtHeart project by Arduino. This means that it’s micro-computer can be used in the same way as a Arduino board. The pins VCC, GND, TST, D11, D12, D13 can be used.


UnlimitedHand’s ICSP port can be used as if programming Arduino’s DIGITAL pins with the functions digitalWrite() and delayMicroseconds(). By doing so, one will be able to control the blinking pattern of an infrared LED or receive remote signals with UnlimitedHand.


1. Preparation

  • - UnlimitedHand and a USB cable
  • - Infrared Signal Receiver Module (PL-IRM1261-C438)
  • - Pin Header (2mm)
  • - Breadboard
  • - Jumper Cables


2. Schematic

The circuit diagram for this project is listed below. Since it is made as a module, the three pins VCC, GND and D12 can be used as is. ( In order to prevent noise from influencing the circuit, please refer to the data sheet and apply an RC circuit.)



3. Building the Circuit


Let us use breadboard and jumper cables to put together the circuit shown below.



4. Installing the Library

We will need to update the program within the UnlimitedHand to complete this project. Download the Arduino Library
We will explain how to install and use the library here.



5. Compiling the Program

Connect UnlimitedHand with the computer, use Arduino IDE to compile the program. To locate the example click on File > Examples > UH > remoteReceive. This program prints out onto the serial monitor infrared blinking patterns received by the device.




6. Operation Test

Once the program has finished compiling, you can take the following steps to make sure it is working.

  • 1. Start up the serial monitor
  • 2. Prepare the pattern that you wish to read with the remote. Point at the receiver and press the button. Press and hold on to the button until the pattern is recognized.

  • 3. If you see characters outputted on the serial monitor, the transmission is complete.

  • Observing the received pattern by the remote
