Running out of GPIO pins? Learn how to connect multiple buttons to just one Arduino pin using clever wiring and resistor ...

Another pin you can use on the Nano to power it up is the 5V pin (located on Pin 27, close to the VIN pin at the end of the board). This pin mostly serves as a power output pin that supplies power ...

To deal with this you’ll want to supply the Arduino 5V via the RAW pin (it’s regulator will then supply 3.3V to VCC feeding the Host Shield and Bluetooth module).

The junction on the voltage divider network connected to the the Arduino analog pin is equivalent to the input voltage divided by 11, so 55V ÷ 11 = 5V. In other words, when measuring 55V, the Arduino ...

If so, remember to connect the VCC pin to 5V of the Arduino board to enable the control input pins IN1 and IN2. Also note at this point that, if you want perfect galvanic-isolation, do not link ...

The 5.2V is safe for all 5V-powered electronics like Arduino, Raspberry Pi, ... – Synchronous operation means you can disconnect the output completely by connecting the ENable pin to ground.

We think of the Arduino as a rapid prototyping tool but we never thought of it as an FTDI breakout board before. [Ihsan Kehribar] wrote a quick post to show how it’s done. You’ll find a… ...
