LM35 Temperature Sensor Arduino Tutorial (3 Examples)

The sensor does not require any external calibration or trimming to provide accuracies of ±°C at room temperature and ±1°C over the −50°C to +155°C temperature range. One of the downsides of the sensor is that it requires a negative bias voltage to read negative temperatures. So if that is needed for your project, I recommend using the DS18B20 or TMP36 instead. The TMP36 by Analog ...

MacroQuest 2 Guides (Introduction)

MQ2 is built for EQ and it enhances the game in basically every single way. This page here is going to go through all of the reasons (I think) you should use the Redguides compile of MacroQuest 2. First off, you usually will not get in trouble for using this software unless you use it irresponsibly. By usually I mean that sometimes Daybreak will decide to suspend people on a whim, out of the ...
