More Progress on XMas Decoration

Posted on November 28, 2015 by larry

I got the IR in and am able to write messages on to the LCD screens. But now I am having stability issues on my ESP8266. Another maker Dave had some recommendations on stabalizing the ESP8266, luckily I have the … Continue reading →

Power Issues With ESP8266

Posted on November 26, 2015 by larry

I am not sure what I am doing wrong, but I really struggled with my ESP8266 and its connection with the Arduino.  After some troubleshooting I figured out it is probably signal quality on the ESP8266.  I cap’d it and … Continue reading →

Programming The ESP8266

Posted on November 25, 2015 by larry

I started programming the ESP8266, for now I just pushout some data so that the Arduino can read it and display it.  It is my hope that the data will be held on the ESP8266 since it has considerably more … Continue reading →

XMas Display 2015

Posted on November 23, 2015 by larry

I made some progress on my Internet of Things Christmas display. This will probably be the minimum configuration, Arduino Uno, 20X4 LCD display, TM1637 and ESP-01. Will work on it some more. Just doing pushups and situps.

Self Shutoff Works

Posted on November 18, 2015 by larry

I figured out how to shutdown the arduino with a TIP-120. I needed a larger resistor though so I put two 10k’s in series. Just doing pushups and situps. Sleeping early.

Self Shutoff Arduino

Posted on November 17, 2015 by larry

I am trying to figure out a way to shutoff the arduino using a TIP 120. Actually is an esp8266 ESP-01 module. I was trying to keep it up with the signal send high through the base of the Tip … Continue reading →
