[00:01] Hello, my name is Sparky Guyer.
[00:04] This is the project I've been working on for the DOE.
[00:07] So what I have here is a setup of three thermal sensors and one heater connected to a Raspberry Pi using interface to heat up the heater which is supposed to heat up a sample.
[00:28] And then I have two thermocouples that are going to be connected to each end of the sample which will then tell me the temperature at each end.
[00:40] I also have a voltage or room temperature reading.
[00:44] Oh, also told me that here are my connections.
[00:49] This is how I heat up the heater using the external power over there.
[00:56] I use a transistor which uses the Raspberry Pi.
[01:06] As a switch which is turned on by my code using Python, that is basically what I'm doing here.
[01:23] Let me show you what happens when I run the code.
[01:27] So here's the code.
[01:31] Person on so that turns on power source.
[01:39] Then keeps up my heater; it's not really connected to anything right now.
[01:46] Who puts output some data.
[01:50] Right now I'm trying to work on doing gives us a graph, but right now I'm trying to work on figuring out about my room temperature value is so random.
[02:04] I'm trying to use foil.
[02:10] To block out the noise, but that doesn't seem to be the issue.
[02:14] What I think the issue is, though, what I'm gonna try is that my one ADC is connected to the same port as my other ADC.
[02:24] And the temperature is based on binary values, right?
[02:29] So like, just maybe, maybe a little binary values from this ADC are interfering with the binary values from this one.
[02:43] So I'm going to try and see what happens.
