I've come to using PuTTy to capture Arduino's serial data to a log file, and then I have a data connection from Excel to that log file for plotting. (I am reading an analog voltage and printing 'millis, value' to serial every 200 ms, it's a very simple program that works great for what I want) Two problems: The voltage I want to measure is likely to range between 25V to 45V. I thought of using a 10k potentiometer to create a voltage divider, but then I lose one bit of resolution (that would map to about 2.2V to 5V). I could ignore this, but it would be good to have the resolution, and I also wonder if there is a better range for the adc, such as 1V to 4V rather than say 2V to 5V? Ever so often, there is a data glitch, it looks like the data in a cell gets truncated or shifted one cell to the right.

It guarantees that when you make a purchase, sensitive data is encrypted and sent to the right place, and not to a malicious third-party. Download iso 9001 internal audit checklist xls files.

Sep 3, 2015 - When you think about serial communications, Microsoft Excel isn't typically the first. With a little coding, be used to send and receive data over your serial port. Frustrating) language that offers a subset of the features from Visual Basic. You can save your Arduino data into csv or tsv file via Python.

The nashville number system ebook torrents germantown. It is a steel guitar, named after the steel bar, but it is also a standard dobro, nothing special.

I suspect this might be Excel accessing the log file (via auto refresh every 1 min) the same time as PuTTy and interrupting the communication to the log file. I could manually clean the data later or just access the log file after the test is complete, but it is nice to see the data plot update periodically. I had initially hoped for a more direct path into Excel from the com port serial stream and have a more live update. Here are a couple VBA scripts I tried that would work once out of a thousand times or just capture some garbage or nothing.

I gave up on them after days of hacking away at found code, but I post them for amusement. Code: Sub Send_and_Read() 'this one seemed to work when sending a 'plain string, and sometime when casing a static integer variable cast as a string(intVar), for example. It will likely stop at the concrete floor, so your carpet may suffer. Nah, if the output of the charger is floating i.e. Not connected to earth, you should be fine. Some galvanic separation between the arduino and the pc would be best. Why not use a (cheap) multimeter with serial output?

Safety and accuracy would be much improved. You can still capture that (optical isolated) data with arduino and log it to a sd card. If you decide to go that route make sure you get a multimeter with a fs9922 chip so I can use that program to.
