This project is the first step in my motion tracking. This Eye was built and adapted from an LRM post here .
please dont laugh at my soldering job, its what i can manage with that kind of board, I like the ones that mimic a breadboard setup. With very little trouble i finished soldering in about 2 hours but had to go back a desolder one transistor and replace it and resolder one wire. After that i tested each IR sensor by themselves to make sure they all worked, each one gave a little different reading off the same IR source but that can be fixed with a little calibration in the software. But for now my goal is to hook it up to 2 servos and control the x and y for the motion tracking, eventually i would like to put this into an enclosure that looks like an eye.
This is to make sure all 4 eyes are working
const int sensepin0 = 0;
const int sensepin1 = 1;
const int sensepin2 = 2;
const int sensepin3 = 3;
int sensorValue0 = 0;
int sensorValue1 = 0;
int sensorValue2 = 0;
int sensorValue3 = 0;
void setup() {
Serial.begin(9600);
}
void loop() {
sensorValue0 = analogRead(sensepin0);
sensorValue1 = analogRead(sensepin1);
sensorValue2 = analogRead(sensepin2);
sensorValue3 = analogRead(sensepin3);
Serial.print("sensor = ");
Serial.print(sensorValue0);
Serial.print(" ");
Serial.print(sensorValue1);
Serial.print(" ");
Serial.print(sensorValue2);
Serial.print(" ");
Serial.println(sensorValue3);
delay(10);
}
this will test all 4 sensors and print to the serial port.
also this code is written for the arduino but can be adapted to other microprossecors.
Here is a screenshot of the schematic as well
Next i will mount it to the servo and start writing the logic for 1 of the axis, but my question is how to mount this to a servo with stuff wround the garage. I will answer this question soo.
and this is why you should never place you MC on your keyboard…………..
that large stack to the left is about 30 print screen applications running. I placed my arduino on my print screen button for about 10 secs before I realized what was going on.
Parts:
- 4x 2n 2222 NPN transistors (generic NPN)
- 4x 220 Ohm 1/4w resistors
- 4x NPN photo transistors
- a bunch of wire
