Ever wanted to remotely control your Arduino ? Or read sensor values, or to make it something ? Maybe even create a remotely controlled robot ? Well now you can. The most basic example will cover; Switch off the LED on and off .

Step-4: Download the PLab app
Step-5: Running the sketch
First , sketch app can find it , a place where there should be . This means it must be uploaded to the Internet .
InterfacesInc.pde only need to upload the app so SimpleButtonExample.pde , internally covers
Sketch run , first connect the device to your Bluetooth or Bluetooth
After successfully loading the sketch , a white button should be visible on the brown background . Pressing the button to go dark a
Step -1: what you will need
- 1 x 220 ohm (or similar) resistor
- Assorted wire
- 1 x smart phone (currently the app we will use only support
- Android, but we are working on getting it accepted for iOS AppStore).
- To use with a Bluetooth LE unit, the phone must support Bluetooth LE.
- 1 x LED
- 1 x Bluetooth or Bluetooth LE unit. The ones we have tested and works:
- Bluetooth: HC-05 and HC-06 (will not be supported for iOS)
- Bluetooth LE: HM-10
Step -2 : Hooking Everything Up
Only now called BT ) Bluetooth or Bluetooth to connect the unit to :- GND on BT to GND on
- Arduino
- TXD on BT to digital
- 10 on Arduino
- RXD on BT to digital
- 11 on Arduino
- VCC on BT to 5v on
- Other side of 220 ohm resistor to GND on Arduino
- LED anode (longest foot, rounded side) to digital 4 on Arduino
- LED cathode to one side of 220 ohm resistor

- Open the source file.
- Press upload.

Sketch run , first connect the device to your Bluetooth or Bluetooth
- Select the device from the list
- Select wheter you want to connect to a Bluetooth or a Bluetooth LE device. To connect to a Bluetooth unit, this unit has to be paired with your phone. This is not neccessary when working with Bluetooth LE.
- It is already uploaded here , it should be possible to directly use the upload . Be aware , and feeds into the app . This can be done by :
- Leave settings andpainstakingly write the entire address into the "Sketch ID" field.
- Go to settings and delete "URL address base" and "URL address end"
After successfully loading the sketch , a white button should be visible on the brown background . Pressing the button to go dark a
