To round out our Arduino category, we also have a complete line of packs. For beginners, check out the Arduino-compatible Adafruit MetroX Classic Kit - Experimentation Kit for Metro 328 or Arduino-compatible Ad

You probably won't have a resistor of the exact value you just calculated, so round up to the next value in the E-12 series. This series only has the values 1.0, 1.2, 1.5, 1.8, 2.2, 27, 3.3, 3.9, 4.7, 5.6, 6.8, 8.2, and those values multiplied by a power of ten, like 10...
I round the values to MM and now at worst I get a variation of +/- 1mm between the two values. #5 The next step to improve accuracy is to make the speed of sound constant a variable as there will be situation of large temperature changes when using the HC-SR04 outdoors. #6 If ...
I am creating a script to auto-detect the arduino on the serial port. For some reason the code I found for this only displays ONE port even if there are TWO ports available. Arduino is on COM5. Any help will be greatly appreciated. If I run the below code, I get COM1 & COM5: ...
