If the app does not detect your device automatically and it does not appear in the All Hardware section, use one of the configuration cards on the top to manually add your device based on connection type. On the Apps tab of MATLAB Toolstrip, under Test and Measurement, click the Hardware...
Arduino does not have the split() function used in the Processing code in Recipe 4.4, but the functionality can be implemented as shown in this recipe. The following code receives a message with three numeric fields separated by commas. It uses the technique described in Recipe 4.4 for receivi...
Below is an example that runs all tests once, then changes a global variable and runs all tests again. To have a bit more direct control over running the tests, this example does not callTest::run()infinitely in theloop(), but instead usesTest:runUntilDone()which repeatedly callsTest::...
You'll understand logic levels and that high does not always equal true because you can see them when you build a simple logic probe. You'll learn how to interface EPROM and EEPROM/FLASH memory as you explore the contents of that old video game or BIOS EPROM. You'll learn how ATA ...
Note: calibrate_scale() uses averaging and does not use the mode set. Note: calibrate_scale() can have a negative value as weight e.g. force of a balloon. Tare & calibration II A load cell + HX711 module without weight gives a raw value, mostly not equal to zero. The functionget_...
to control pretty much any shade and brightness of any number of pixels connected in series. The other advantage is after setting the desired combination of colours Arduino does not need to interact with them any longer, thus processing power can be used for something e.g. controlling the quad...

In your conditions, you can use these test operators: == (equal to), < (less than), > (greater than), <= (less than or equal to), >= (greater than or equal to), != (not equal to). And you can also use the logical && (and) and || (or) operators. ...
