![]() It's that simple!Īnd you don't need anything But a DS18B20 can work. On the left is the resistor everybody is talking about! The resistor goes between GND and A0 (or any analog pin you like) and the thermistor goes between the same analog pin (A0) and 5V. On the right side you see the thermistor with just 2 connections. You also connect A0 to Ground with a 10K resistor.Īaaa, got it, so I'm splitting ground with resistor, so it goes like this: One wire from your thermistor goes to +5. I'm learning so much from this, really thank you all for your replies. To be honest, best way would be somehow get temperature of cpu from the motherboard itself - there are many cpu temp software that have this info - how easy would be to get it and use/send to Arduino? If the thermistor says it's 10K, what does it actually mean? Isn't that 10K Ohm, so it already has a resistor? WOuld I still need to solder resistor to one like this? First I need to put together this thermistor, I hope I won't kill any of the items plugging the one I have to it. I found this code here on this forum - not sure if this is gonna work. Thank you, it sounds like the thing I should do now. Then map the analog values into temperatures, of the desired scale (C/F/R/K), convert it into digits, and send them to the nixies. Now you're ready to read the voltage, using analogRead(), and output by Serial.print(). ![]() Connect it to Vcc and Gnd, and the center tap to an analog input. You have to add an resistor to your thermistor, to form a half bridge. Should I build a remake of that calculator now, using an Arduino?īut back to your problem. I used nixie tubes for my first computer, 50 years ago, driven by relays because no transistor supported the high voltage at that time, and a phone dial plate to enter digits. and how did you come up with that I don't use tubes?Īll works fine, tried few simple codes like blinking tubes, counting down etc.Ī nice module, the backlight idea is great ![]() Game rules: Post links to each piece of hardware - and specify which Arduino (though one would suspect, a UNO) - you are proposing to use. So you clearly are not using Nixie tubes. that requires somewhere around 70 volts and a current limiting resistor to operate. NIXI tubes use ionized neon gas to make the lighted character display. I know that this can be plugged to arduino easily with two pins.Ĭouldn't find anything like that, but maybe someone already tried this and have a simple code I could use? I have one old thermistor, I believe it's 10K, I used it ages ago, that looks like this: Now, what is left is to get thermistor sticked to cpu cooler radiator and plug it to arduino, then write a code that reads temps and passes to nixie modules. ![]() I have installed everything, added nixie module library, connected my arduino to pc via USB cable, connected nixie tube modules to it and I'm running simple code I found on Nixie modules website that changes numbers and background color. Now, please forgive me but I have NO experience in programming and electronics, so this is almost impossible to do this by myself, that is why I'm asking you guys for help I have purchased everything I need - Arduino, nixie tubes, nixie modules v2.0 and wires. I would like to have a simple 2 nixie tube CPU temperature display mounted in my computer. I have just started my "adventure" with Arduino:)
