Thanks for the overview. I now understand the differences. Your work is great... I am glad you continued to improve it for us.

Doug- I have been following your threads for quite a while as I built my three keg super strut system over the last 15 months. I hacked Android onto an HP TouchPad and installed the server on an Rpi and the app on the Touchpad. I have also been building a TeensyPi and a TeensyNet on Jim...

I have Teensynet 14.0 boards on the way... I am going to give it one more shot. At least the teensypi works, if the need arises. In my researching around, how many amps are needed to light up the wiz820io leds on the teensynet boards? I have 2 amps right now, and lack of amps may be the issue...

Yes, they finally showed up along with some of the sensors. Now another issue... the wiz820io is not working, therefore no teensynet.local webpage data. I am looking through the net trying to trouble shoot it. On the PJRC website, you stated that you made the board using D23 for the WIZ820io...

OK, here's the scoop so far. I soldered together a second teensynet, and a teensypi. I followed the trouble shooting steps above. Everything is going well until I put a temp sensor in the action board. Nothing found. I then un-jumpered and wired the action board into the teensypi (with 3v3...

I did a dumb novice thing (which l am a novice). The tantium capacitors were not all the same polarity in the board. One is soldered one way, the other is the opposite. I don't know what that does to the circuits, but the markings are so small, I now know I need a magnifying glass to figure out...

The wall wart is a repurposed 5v, 2amp unit taken off of an old tablet. I measured the output to be 5.2 v. I am soldering together a teensypi board now just to be able to look for an address within Linux just for the heck of it. I was able to find the addresses of the switches and temp sensors...

I greatly appreciate your time and help. By "pegging" I mean my analog multimeter measures much greater than 5v. I only have two DS18B20s left (I keep breaking the leads). Both show toggling of voltage but do not register any addresses. I guess the fun is over for now until I get a bunch of...

I checked with the first script. Every line is pegging the multimeter. I removed the jumper, it is now alternating from 0 to +5v on all lines and boards.

I jumpered both the action combo and LCD boards. No joy. "No more addresses'. LCD is not working either.

I had bought some Fairchild replacement BS170s earlier. Q2 was bad, replaced it. Loaded the first sketch, SDA, SCL, and Data lines all alternate between 0 and +5v on all boards! Loaded the second sketch... serial monitor states "no more addresses". LCD no longer lights up. Progress made...

OK, Thanks, this is very helpful. The SDA and SDL lines alternate from 0v to +5v after loading the first program. The data line pegs the multimeter. Soldering has no bridging. Can I troubleshoot which bs170's related to the data line that might be defective? I tried to take an unpopulated board...

l meant to ask you about the 4k7 resistor... As I put one in the "optional" 4.7k spot on the teensy board. Also I have the jumper on the 5v side of the LCD board. Do I need to place an additional 4k7 resistor in the circuit? Is the jumper for voltage correct?

Thanks to both Jim and Yuri for taking time out for explanations... The last time I did programming was in fortran 77, with stacks of punch cards! Using either method of modding the teensynet.ino file, there is no output to the serial monitor for any chips, either the switches or sensors. I used...

Thanks, Jim, I did not put he cumulative value on one line, I put in two lines. I will send you the results.

I see the teensynet.ino code in the IDE, but I do not know how to change the values you have asked. As for the code for the I2C scanner, I should copy/paste, name the sketch something like I2C.ino and compile, right? I am not familiar with the code language. Please bear with me.

OK, here goes... I have included a pic of the current setup, and a schematic. I was able to compile only using linux (Debian 7- SolydK to be exact), not with Win 7. Teensynet.ino is compiled on a teensy 3.1. I am using the 16 G image you have provided on a 16 G Class 10 Sandisk Ultra card on...

Jimmay- In an earlier post I stated that I had gtent the RPI, WIZ820io, the teensy 3.1, the teensynet v5.2 board, and the TL-WR70N, combo action board, and the RGB LCDs and boards. I need to get this on my rig and start rockin'. I can't get these boards to work together as l do not know how they...

Day_trippr - that was it! Thanks for the help.

I have the same issue, except that I am wiring two 115v pumps from a gcfi to two single throw switches. The wiring in the diagram does not work, because of the extra connection to center, which is not present in the single throw switches. Any help for a guy in the States?
