Debugger for Arduino - CodeProject - For those who code

Oct 09, 2015 · The ARDUINO=10800 seems like a definition of some symbol for the compiler. It probably just tells the Arduino libraries which version of the code is present. The cpp_properties file is from the blink example project provided with the extension. In an earlier file I don't have this definition so probably they added it just recently.

Guide for MQ-2 Gas Sensor with Arduino | Random Nerd Tutorials

May 05, 2016 · The MQ-2 gas smoke sensor is an analog sensor. It outputs a voltage between 0 and 5V accordingly to the gas concentration in the atmosphere. The greater the gas concentration, the greater the output voltage. The lower the gas concentration, the lower the output voltage. When the Arduino reads analog values, it returns 1023 when it reads 5V, and ...
