I'm not sure what the 4050 buffer chip is used for. (Some older flashes put as much as 300 volts through their sync terminals.) The Optoisolator also serves to protect the Camera Axe from those high voltages. It protects the camera axe from the high voltages sometimes present in cameras and especially in flashes. Internally it uses an LED and a phototransistor to decouple the input from the output. The Optoisolator chip provides electrical isolation between inputs and outputs. LTV-847 Optoisolator (Left)74hc4050 Buffer Chip (Right) Why we need this chips when we build the Camera Axe 5 Shield The Camera Axe library has special methods that provide very fast-responding digital read, as well as nanosecond timing information. Normally the digitalRead method is too slow for accurate timing, as is the micros() function.

The Camera Axe makes use of special software to calculate the timing accurately. Yes you could, but then the burden of making it work would be up to you.

The arduino cant calculate the time in nanosecond so how this person could use ARDUINO UNO R3 to calculate the Time From Sensor SignalĪnd can some one explain this code in menu01_projectile.ino how it workĭirectly to arduino input digital pin with out use the Camera Axe 5 Shield Look for sensor2 to detect search in internet

If (readSensorDigitalFast(0) = lowHigh) // If sensor1 detects projectile The function used to start timer in arduino in milli and microĭistanceBetweenSensors = 200 // Distance between sensors is 2.00 inchesĭistanceBetweenSensors = 508 // Distance between sensors is 2.00 inches (or 5.08 cm) If you go to arduino refrence to read the function of programming language you will see I download the source code for this sensor to use it in Arduinoīut if find something unable to understand Im trying to make device using arduino mega or UNO to measure the speed of bullet by using Projectile Sensor From Camera Axe
