voidsetup() { //The following code will be executed once when your Arduino turns on. pinMode(13, OUTPUT);//Set pin 13 as an 'output' pin as we will make it output a voltage. digitalWrite(13,HIGH);//This turns on pin 13/supplies it with 3.3 Volts. } ...

I added one more feature to this airplane, and that’s a simple LED which will indicate if the battery is empty. Using a simple voltage divider, we drop the 12V coming from the Li-Po battery to around 5V so we can read them with the Arduino analog input and so know when the battery...
To control high-voltage or high-power circuits with an Arduino, you have to isolate them from the Arduino with a relay. Here's how! To control high-voltage or high-power circuits with an Arduino, you have to isolate them from the Arduino with a relay. Here's how! Circuits that operate...
Arduino and HC-12 Now let’s connect the HC-12 module to the Arduino and make the first example. Here’s the circuit schematics. The operating voltage of the module is from 3.2 V to 5.5 V and for more stable work it is recommended to use a decoupling capacitor and an external powe...
Alternatively you can also reach the debug configurations menu by right-click on your project under the arduino view.From the “Run” menu, select “Debug Configurations”. Double-click on “GDB OpenOCD Debugging” to create a new configuration and set the configuration name....
How to reprogram when using GPIO0 as an output Note: GPIO0 is needs to be grounded to get into programming mode. If you sketch is driving it high, grounding it can damage you ESP8266 chip. The safe way to reprogram the ESP8266 when your code drives the GPIO0 output is to :- ...

Arduino is mainly used to build electronic projects for everyone – electricians, tinkerers, hobbyists, makers, and beginners. You can feed an Arduino board a set of instructions for it to carry out certain tasks. It is able to read the inputs and turn them into an output, for example,...
an ISR,I speculate the shortest pulse you could measure is 5us.Otherwise, the pulse will be over before you can even grab a timestamp from the leading edge of it. An Arduino can easilyoutput a pulse, using the Output Compare registers in a timer, of 62.5ns,however, since that is the...
