Arduino Nano INPUT_PULLUP Template: The Arduino Nano is a great platform for small projects, and what makes it even better IMHO is having a standard switch/power layout to take your prototypes from 0 to done in record time. This howto will show how to pu
void setup() { pinMode(3, INPUT_PULLUP); }This can be useful when you don’t want a pin to be floating, e.g. when you connect a button to a pin.Note that the analog pins can also be used as digital pins, using the aliases A0, A1, etc. The exception is the Arduino Nano’...
Input and Output Each of the 14 digital pins on the Nano can be used as an input or output, using pinMode(), digitalWrite(), and digitalRead() functions. They operate at 5 volts. Each pin can provide or receive a maximum of 40 mA and has an internal pull‐up resistor (disconnected ...

Tinkercad supports a curated set ofArduino boards(Uno, Mega, Nano) and components, prioritizing ease over complexity. It’s not built for advanced microcontrollers or low-level debugging, but its real-time simulation—watching LEDs pulse as your code runs—is instant gratification. ...

The processor has plenty of GPIO, Analog inputs, hardware UART SPI and I2C, timers and PWM galore - just enough for most simple projects. When we need to go small, we use a Metro Mini or a Trinket M0, but when size isn't as much of a concern, we reach for an Adafruit METRO. ...
pinMode(pin,INPUT_PULLUP); Both have the same effect, but the latter one is preferred, because it is more readable. Note: if you forget to use pinMode(pin, OUTPUT), and you use digitalWrite(pin, HIGH) afterwards, you'll just enable the pull-up resistor, because all pins are set as...
The hookup is pretty straightforward, essentially we are connection the three potentiometers to three analog inputs and the three MOSFET modules to output pins that are capable of PWM. The LED strip lights are connected to the power supply through the MOSFET outputs. Here is the sketch we wil...
