Saving electricity is an issues that many suffer from, and creating a product or a reminder to notify about electricity abuse is complected and hard. So this product (Sunlight Sensor) was creating for the purpose of save and prevent electricity intemperance.
How We Create it
To Create the Sunlight Sensor we used two particle photons, two breadboard, connection wires, servo motor, power bank and a 22.1k ohm resistors. We combined these components together to make a very simple and effective product, where we used the two photons for a different objectives, the first photo-resistor (sensor of light), the second photon is the one that take the transmitted info from the cloud and translated it into the servo motor to make it move the switch. We executed this operation while using a 20000mA power bank, that will be providing a full power to the whole operation for 20 days straight. So the operation steps are detecting the sunlight by the photo-resistor and send info to the cloud, then the cloud transfer the info to the second photon and force the servo motor to move and move the switch with it accordingly.
This code accepts the event "light_output69" and actuates the servo to turn the light switch off.
Servomyservo;// create servo object to control a servo// a maximum of eight servo objects can be createdvoidsetup(){myservo.attach(D0);// attaches the servo on the D0 pin to the servo object// Only supported on pins that have PWMmyservo.write(10);}voidloop(){Particle.subscribe("light_output69",lightsOut);// Subscribe will listen for the event buddy_unique_event_name and, when it finds it, will run the functiondelay(1000);}voidlightsOut(constchar*event,constchar*data){/* Particle.subscribe handlers are void functions, which means they don't return anything. They take two variables-- the name of your event, and any data that goes along with your event. */if(strcmp(data,"on")==0){// if your buddy's beam is intact, then turn your board LED off and move servo to 180 degreesmyservo.write(33);delay(1000);myservo.write(10);}}
Photo Resistor
C/C++
This code detects light and sends out the event "light_output69".
