• Connect the components mentioned above as you can see in the fritzing diagram below.

Note: Download the project code here.

• Workshop 4 – 4Duino Basic Graphics environment is used to program this project. (The same could be implemented in the latest Arduino IDE)
• This project requires the Arduino IDE to be installed as Workshop calls the Arduino IDE for compiling the Arduino sketches. The Arduino IDE however is not required to be opened or modified to program the 4Duino.
• Open this file using Workshop 4.

• Change the SSID and the PASSWORD to suit your router, in the program.

• You can change your Home Security Password in line 62 ( char pass[7] ) , and your reverse password in line 64 (char inPass[7]).

• Connect the 4Duino to the PC using uUSB cable.
• Then navigate to the Comms tab and select the Comms port to which the 4Duino connected
• Finally, go back to “Home” tab and now click on the “Comp’nLoad” button.
• Workshop 4 IDE will prompt you to insert a µSD card to the PC in order to save the widget images. Select uSD card to be loaded and Click “OK”.

• All you need to do is insert the uSD card to load the image files to into the 4Duino.
• After uploading the program in to the 4Duino, it will try to mount the uSD card. If the uSD card is not inserted it will print an error message

• If you want to use the project away from the PC (e.g. door, vault), apply a portable 5V power supply to the 4duino.
