Arduino Laser Tripwire
I had an idea that could help people who want to build this: why don't you make the value below which the alarm should be triggered a variable that can be changed with a potentiometer? After all both components are resistors, which means they "create" an analogRead between 0-1023...I hope this helped someone and good luck with the project.
Bad idea...Just use if digitalRead(1, HIGH) || digitalRead(2, HIGH) etc.(|| means or).You can thank me later.
hi. I was wondering if I could use the Keyes laser beam and the laser detector to activate a servo motor? I've already got code for activating a motion sensor but I would like to use a tripwire beam to activate a servo. Can this be done and is there any Arduino code for it?
which anode and cathod will make highest amount of oxygen and hydrogen i dont care about the cost tell me the best output material for hydrogen and oxygen production
Do not EAT or DRINK any of that. You will make horrible heavy metal exposure into the water as it degrades the metal into sharp, cancerous, stomach ripping metals over time
It should work as is, gust use different inputs in your ardino and add the if()... code for each photo resistor.
No, actually Alluminium corrodes so fast you won't believe it...
I've seen graphite and platinum been recommended as they wont be corroded (?), but any conductive metal will work. Mix bi-carb with the water to make it conductive, and you only need 1.23 V for electrolysis, a higher voltage with just generate more heat; more amps is what you need to create more bubbles.
