You aren't going to heat a nichrome wire by simply connecting it to an Arduino. First, the Arduino can't supply enough current to generate any significant heat; and second, your nichrome wire will look to the Arduino as a short circuit and possibly damage it.If i connect a nichrome wire to arduino , will it be a short circuit ? or it will be a resistance that is connected to arduino , I need to heat the nichrome wire ....
I need to heat a100 mm diameter dish to 37 deg c at may be 5v and 2A and i am looking to find which heating element that may be suitable, but i need to design a heater my self or find one that is suitable so that i can wrap it around the dish and keep light going through it . and then control its temperature with arduino.Unless it is a very, very, long thin wire the arduino will see it as a short circuit.
What length and what diameter is the wire?
Wrapping a wire around it will not give even heat. Make an incubator box with fan and heater (almost any source...light bulbs to heater elements from hair dryers or homemade) as suggested in one of your previous threads on this subject. If you want to incubate in the dark, that is easy. Connect the heat box to the incubate box with a duct. If you want a microaerophilic environment, you can add CO2 much easier (and safer) to a box incubator.I need to heat a100 mm diameter dish to 37 deg c at may be 5v and 2A and i am looking to find which heating element that may be suitable, but i need to design a heater my self or find one that is suitable so that i can wrap it around the dish and keep light going through it . and then control its temperature with arduino.
I came up with some type of resistive wire that i can wrap around it but which wire/heating element i should use, that's the problem...
