Hello!!!
I am new to arduino and programming in general and am not incredibly tech-savvy so I am asking for help with this project I am making!
I am looking to take this light source (a vintage x-ray machine) and put it on a timer to turn on every 5 minutes! so it would be
power on for 5 minutes > power off for 5 min > power on for 5 min> etc.
I truly dont even know where to start on this, so please let me know if you know of any tutorials or something for a project like this!
seems you don't need an Arduino, just a mechanical timer would do
just find one with 5 minutes resolution
I really hope the old x-ray tube is replaced by some Edison stuff....
Or trybthe BLINK examples, using a 5 minute interval…
As you get the idea, you can move on by removing delay(), and adding other ‘smart’ features.
"Playing" with an x-ray machine would be a very dangerous practice.
Not only for you but for others within range of the transmitter.
I think the moderators should step in here before you do irreversible damage.
There is just a normal bulb in it! It's not that old!
It is basically just a light box, not old enough to have any toxic gasses or anything!
Hello prisybha
Take a view here to get some ideas:
Have a nice day and enjoy programming in C++ and learning.
MIND THE GAP
What is the voltage and current (or wattage) of the light source? How do you plan to switch it with the Arduino's 5 volt, 20mA output?
A 5 minute cycle timer for Nano, UNO, ProMini:
const byte lightPin = 8; // pin 8 turns ON/OFF every 5 minutes
void setup()
{
pinMode(lightPin,OUTPUT);
}
void loop()
{
static unsigned long timer = 0;
const unsigned long period = 600000, // 10 minutes
onTime = 300000; // 5 minutes
digitalWrite(lightPin, millis() - timer < onTime);
if(millis() - timer >= period)
timer += period;
}yes! sorry for not specifying!!
Speaking of vintage x-ray machines, one has been sitting in my garage (an Image Intensifier) for at least 20 years as I recall. I have never attempted to fire it up and would probably need to do so with a Variac in order to re-form the electrolytics safely, not to mention the state of the transformer oil.
Not even sure who I could pass it on to for recycling.
eBay?
