Automatic Resistance: Resistors Controlled by the Environment

Resistors are one of the fundamental components used in electronic circuits. They do one thing: resist the flow of electrical current. There is more than one way to skin a cat, and there is more than one way for a resistor to work. In previous articles I talked about fixed value resistors as well as variable resistors. There is one other major group of variable resistors which I didn’t get into: resistors which change value without human…

NEW PRODUCT – Adafruit Universal Thermocouple Amplifier MAX31856 Breakout

NEW PRODUCT – Adafruit Universal Thermocouple Amplifier MAX31856 Breakout Thermocouples are very sensitive, requiring a good amplifier with a cold-compensation reference, as well as calculations to handle any non-linearities. For a long time we’ve suggested our MAX31855K breakout, which works great but is only for K-type thermocouples. Now we’re happy to offer a great new […]

Adafruit MAX31856 Universal Thermocouple Amplifier

Now you can handle any kind of thermocouple! Thermocouples are very sensitive, requiring a good amplifier with a cold-compensation reference, as well as calculations to handle any non-linearities. For a long time we've suggested our MAX31855K breakout, which works great but is only for K-type thermocouples. Now we're happy to offer a great new thermocouple amplifier/converter that can handle just about any type of thermocouple, and even has the…

News • Re: Wierd errors with Arduino 1.6.9 and ESP2866 platform

Found the cause of the problem.The DS1307 library uses Time.hThere is a time.h which is part of the IDE and Windows is not case-sensitive in file names, so we get a conflict.I edited the DS1307 library to be ArduTime.h instead - problem gone!Peter.Statistics: Posted by OldBikerPete — Sun Sep 25, 2016 6:39 am

ESP8266 Docs

 

Documentation • Re: How to program ESP8266-12F?

COM1 may not be the right serial port. Do you get any lights flashing on the USB to serial converter? If not then select a different serial port. Also you need to have specific pins set at specific logic states. Ignore the deep sleep resistor connection. GPIO0 (burn) must be low, then do a reset and the blue light on the module should flash once. Then try loading the sketch.Statistics: Posted by rudy — Sun Sep 25, 2016 8:38 am
