Hello
Today I wanted to connect my BAspi to a Current Transformer, but I ran into a roadblock. In Week 2, I changed the IP Address of my Raspberry Pi and now I wasn't able to access my BASpi. So, what I did was just reformat my SD Card. Here is a picture of my reformatting set up:
Next, I took a 5 Volt to 10 Amp Current Transformer and put around the Black wire coming from a light bulb. For safety reasons, I wrapped a 1K ohm resistor around the leads I put in the CT which I also had connected to my Multi Meter. I connected the White and Black wires from an electricty cable to the White and Black wires on the Light Bulb respectively. I didn't use the Green Wire on the cord. I plugged in the the cord and measured the voltage with my Multi Meter. I got 52 millivolts. Here are some pictures of my setup and I also included a picture of the CT I used above:
Since my CT is 5 Volts to 10 amps this means that if I have 5 Volts, I'll get 10 amps. 2 volts which get me 5 amps, and so forth. Put the cord is supplying the bulb with 120 Volts which is way over the 5 Volt scale, then why am I getting 52.0 millivolts?
Afterwards, I reformatted my SD Card agian, but I used a computer in C505 rather than my tablet. It only took a few minutes and when I hooked up my Pi, it booted up correctly and I was able to access my BASpi. Here is my setup:
Here is the guide I used to reformat my SD Card: https://www.ccontrols.com/pdf/is/BASPI-soft-install-guide.pdf. Next week, I'll hook up my BASpi again and start programming in Sedona, as well, as figure out how Current Transformers work.
