Phantom 3 Payload drop

thingiverse

a drop mechanism for drone. i use it for fishing. for 2 years.(it rust from the salt...but its ok). i switch to a other model...but it my be useful for somebody... stuff: 2 M2 10mm bolt and nuts...for motor. 2-3-4 bolts and nuts for bridge. 5CM shrink tube for photoresistor. switch sg90 100k resistor 100k Photo resistor Arduino nano connector for 2 wire...i forget the name of them 2 battery connectors...i use old ones. stainless rod 1mm. printed scale 105%...become abs shrinks(i don't want to fight the battery to fit) ...100% infill(good for drilling holes later) dry fitted. soldered Arduino. only pins A0, d5, gnd, 5V. boot loaded, code: // Include the Servo library #include <Servo.h> // Declare the Servo pin int servoPin = 5; int sensorPin = A0; int sensorValue = 0; // Create a servo object Servo Servo1; void setup() { // We need to attach the servo to the used pin number Servo1.attach(servoPin); } void loop() { // read the value from the sensor: sensorValue = analogRead(sensorPin); if (sensorValue < 700) { // Make servo go to 0 degrees Servo1.write(190); delay(100); } else { Servo1.write(80); delay(1000); } } test on Breadboard...and solder...(schema on photo) you need drill hole for motor and for brige. photo resistor attached to one of the front LED’s on the drone(on phantom 3 at least)- it should be close in duct tape from any ambient lite for it to work properly. you can play with sensitivity in the code(sensorValue ) attach it to some kind of bridge for simplicity: https://www.thingiverse.com/thing:2055189
