This tutorial explains how to get started with your 1Sheeld, if you don’t have a general working knowledge of Arduino and Arduino programming, we recommend you check out the instructions and tutorials on the Arduino website.
– 1Sheeld Library works on Arduino IDE 1.0.5+
– 1Sheeld+ based on a BLE “Bluetooth Low Energy” technology which is supported only by devices that has bluetooth 4 , So please check if your device has the technology specially in old android/Iphone devices.
Step 1: Gather your materials
- Arduino board (UNO-DUE-MEGA or any board with a similar form factor for Arduino shields)
- USB cable
- Android Smartphone
- Jumper wires (Male to Male)
- Resistors (1kohm)
P.S: you don’t need to buy any sensors because you already have them in your smartphone.
Step 2: Adjust 1Sheeld
Warning! If you have the Arduino Due or any board that works on 3.3V, you must switch your 1Sheeld to operate on 3.3V since it may damage your board. To switch 1Sheeld to 3.3V locate the toggle switch on the top of the board and switch it to the 3.3V position.
Place your 1Sheeld on your Arduino board then plug the Arduino to your laptop or PC.
1Sheeld works on Arduino (Uno/MegaADK/Mega2560/Leonardo/Due).
Please refer to (using 1Sheeld with different Arduino boards tutorial) for more information on adjusting 1Sheeld on your Arduino board.
Step 3: Download 1Sheeld Application onto your smart phone
Step 4: Download 1Sheeld library
For users having Arduino IDE prior 1.6.2, download 1Sheeld library.
Then, after you successfully downloaded the library, extract the files in Arudino’s library directory “Path\UserName\Documents\Arduino\libraries”.
Step 5: Write your Sketch
Open Arduino IDE on your computer, write your sketch according to your project and the shields you will use in that project, or you can choose an example from our library’s examples.
Let’s try a simple example of the mic shield, we will use the mic to turn an LED on if the noise in the room exceeds a certain level.
You can open the mic shield example from the examples tab as shown above.
Note: there’s a forced delay inserted in sending any frames from 1Sheeld Library “about 200 msec between each frame sent” to sustain sending/receiving frames between the application and the Arduino.
Or use Codebender.cc
Step 6: Upload your sketch
Here comes the most important part of the whole tutorial, switch 1Sheeld to the Uploading-mode (this is the switch labeled UART Switch on the board) before you upload your sketch to the Arduino board to avoid serial conflicts between 1Sheeld and Arduino, then press the Upload button in the IDE.
Upload mode is turned on when the UART switch is pushed away from the 1Sheeld logo. Or if you have 1Sheeld+ switch it to the SWS “Software serial” sign that appears on the board.
Step 7: Once you have completed your upload you need to switch 1Sheeld back to the operating mode
Don’t forget! If you don’t switch the UART Switch back to the operating mode your project will not work properly as you will have no communication between 1Sheeld and the Arduino board.
Operating mode is turned on when the UART switch is pushed closest to the 1Sheeld logo. Or if you have 1Sheeld+ switch it to the HWS “Hardware Serial” sign that appears on the board.
Step 8: Use 1Sheeld Application
Open 1Sheeld application on your iOS or Android smart phone. The application will first scan over bluetooth for your 1Sheeld, it will take a few seconds and the phone will find it. Once it appears on your screen as 1Sheeld #xxxx, you will be required to enter the pairing code (the default pairing code is 1234) and connect to 1Sheeld via bluetooth.
Note: If you are having trouble please make sure the bluetooth is turned on for your Android phone and that the Android phone is close to your 1Sheeld.
If you get an error message as shown below that your phone cannot find 1Sheeld, press the reset button on 1Sheeld and try again.
Note: Make sure that the UART switch is on the operating mode.
Step 9: Access Shields
Select the shields you would like to use in your Arduino sketch (project) and press on the multiple shields icon at the top right of the app.
In this case, use the Mic shield and have fun prototyping!
Refer to the documentation pageto know how to use each shield.
Rarely the first time playing with 1Sheeld may not work properly so please make sure to upgrade the firmware by pressing the Logo on the application while connected “Blue led on board is steady” and then choose upgrade firmware then press upgrade. “You may also need to check your internet connection before the trial or it will state upgrade error”
