Making mosquitoes stay away from your yard.
There is no known alternative solution for people to set up open, mosquito free islands for their day to day activities . . . . their animals too.

Material:
6 5050 RGB LED.
6 220 Ohm resisors.
1 Aurdino as module since the system only use 2 output.
Schematic: The attached file draws 1 RGB LED, you will use 6 in parallel.
Layout Configurations: Please see the second attached file:They are the insides and the finals that we distributed for humanitarian purpose.
Sketch:
#define RED_LED 4
#define BLUE_LED 5
// Per schematic the LEDs pins, set low to turn ON.
#define RED_ON digitalWrite(RED_LED,false)
#define RED_OFF digitalWrite(RED_LED,true)
#define BLUE_ON digitalWrite(BLUE_LED,false)
#define BLUE_OFF digitalWrite(BLUE_LED,true)
void setup() {
pinMode(RED_LED, OUTPUT);
RED_OFF;
pinMode(BLUE_LED, OUTPUT);
BLUE_OFF;
}
void loop() {
// optional testing procedures
while(1){
RED_ON;
delayMicroseconds(500);
RED_OFF;
delayMicroseconds(500);
BLUE_ON;
delayMicroseconds(500);
BLUE_OFF;
delayMicroseconds(500);
}
}
Usage: They are not intuitive, and difficult to use. Please follow the instruction carefully.
The keyword is 'shadow' and 'line of sight'. shadow is the place mosquitoes can hide out of line of sight and become a highway for them to into the object in the middle. Our observation show mosquitoes don't go further more than 3 feet under 'line of sight' area to get into the object.
The unit is ineffective within 2' right up front of the LED. Please don't test by put them next or near you. It doesn't work that way.
It works day and night.
For single unit:
Although we have to have provide guides for single unit usage, It's never been a recommendation. At least 2 one covers the shadow of the other.
Imagine that the unit has 90 degree shining angle, It must be place up high, to generously cover all around the footprint of the shadows of the subjects (at least 3' buffer). Then you are safe. - Don't worry about the effective radius which is very far 100's (only if the above conditions met.)
For multiple units:
We have use 4 unit at 4 corners for a 100 boy scout group. As long as shadow of one is cover by the other.
Make sure you are far enough for the light covers all around you: For single person the light should be at least 8' away, for a large group about 10 people it could be as far as 30' away, etc . . .
