Hey everyone, in this instructable I will show you how to make an LED light for photography. It can optionally be controlled by a smartphone.
Step 1: Parts and Tools
Here are the parts and tools that you will need to make this project:
Ultrabright white 5mm LEDs (x6)
Linkit ONE board with WiFi antenna
2n2222a NPN transistor
1k ohm resistor
Computer with the latest version of the arduino IDE and linkit ONE drivers
Desktop printer (for template)
Soldering iron and solder
Hot glue gun and hot glue
Step 2: Cut Out Template
Using a desktop printer, print the attached template. Then, cut it out on a bandsaw. Cut out the "bottom" piece in either translucent white or clear acrylic. I chose white.
Step 3: Glue Enclosure Together
Glue the long rectangular side pieces to the smaller side pieces at a 90 degree angles. Then, add glue the second long rectangular side piece to make one big hollow rectangle. Now, glue the white or clear piece to the bottom of the hollow rectangle. Don't glue the remaining top piece on yet.
Step 4: Glue LEDs
Hot glue the LEDs to the box, one in each corner and one at the middle of each side piece.
Step 5: Wiring
Use the wiring diagram to solder all electronic components together.
Also, you will need to attach the WiFi antenna. Do so by flipping over the Linkit ONE board and plugging the small uFL connector to the connector that says "WiFi/ BT ANT".
Step 6: Code
Download the (1st) attached code, open it, and modify the line that says: "#define WIFI_AP "Your Network"" by changing out "Your Network" to the name of your WiFi network. Do the same for the next line, only you will type in the network password this time. Now, upload the code to the board. Once that is done, open the serial monitor and copy the first IP address shown.
Now, download and open the 2nd attached code and change out the same two lines as last time. Then press upload.
Step 7: Testing...
To test the light,
