Can I Use The Analog Pins On The Arduino For My Project As Digital?

Answer : You can always use the analog pins for digital writing. digitalRead() works on all pins. It will just round the analog value received and present it to you. If analogRead(A0) is greater than or equal to 512, digitalRead(A0) will be 1, else 0. digitalWrite() works on all pins, with allowed parameter 0 or 1. digitalWrite(A0,0) is the same as analogWrite(A0,0) , and digitalWrite(A0,1) is the same as analogWrite(A0,255) analogRead() works only on analog pins. It can take any value between 0 and 1023. analogWrite() works on all analog pins and all digital PWM pins. You can supply it any value between 0 and 255. The analog pins let you read/write analog values - basically, instead of giving out a voltage of 0 or 5 (as with digital), they can give a range of voltages between 0 and 5 (both as input and output). Note that the voltage during analog output is only the observed voltage with a multimeter. In reality, the analog pins send pulses of 0V and 5V signals to ...

Check Real Size Of USB Thumb Drive

Answer : f3 - Fight Flash Fraud There is only one alternative I found, but I think this is even a better one than the original h2testw tool for MS Windows. Fortunately, it is really easy to use, even from command line. There are GUIs available, though. There is also a lot of information about the implementation and the problem with fake drives on the tools website. Main page (source code): Documentation QT GUI f3 offer two methods: f3probe method: Much faster h2testw method: Slower. Also test R/W performance. Probably more reliable. The f3probe method (recomended) f3probe is one way to test the drives, not as accurate but faster since it does not write on the whole drive. You can read more about it on the tools website. If you want to be 100% sure, better use the h2testw method. As the developer describes on the website: f3probe is the fastest way to identify fake drives and their real sizes. And: Finally, thanks to f3probe being free software, and once f3probe ...

Apple - Change Click Firmness Of Apple Magic Trackpad 2

Image
Answer : Not an answer yet , but I came across the same issue earlier this week. I tested it on a variety of Macs (two MBPs and one iMac Pro) running El Capitan, Sierra and High Sierra respectively. In all cases the Trackpad settings provided no click pressure options, or Force Click/haptic feedback option. I've got a case open with Apple Engineering and will update this answer when I hear back. Update I've spent the last week troubleshooting this with Apple and we've confirmed this is an issue with how macOS High Sierra interacts with the Magic Trackpad 2. In our testing we found the following: A Magic Trackpad 2 connected to any model MacBook running El Capitan or Sierra will display the Click pressure slider and the two checkboxes relating to Force Click/haptic feedback and Silent clicking A Magic Trackpad 2 connected to any desktop Mac running El Capitan or Sierra will display the Click pressure slider and the two checkboxes relating to Force Click/...
