Keyestudio UNO R3 development board is a microcontroller board based on the ATmega328P (datasheet), fully compatible with ARDUINO UNO REV3. It has 14 digital input/output pins (of which 6 can be used ...

This library is used in order to abstract away a few of the details to do with analog multiplexing and demultiplexing. It assumes the following: The multiplexer is analog and is compatible with the ...

The build relies on that old stalwart, the Arduino Uno, to run the show. It’s hooked up to a DS3231 real-time clock module so it can keep accurate time for long periods, as is befitting a clock.

It comes with multiple adapters, including the one shown, a two-wire quick-connect adapter. The red connector is positive and feeds the Nano’s VIN pin; the black is negative and feeds the GND on the ...

This article is completely focused on Arduino UNO only, if you want to know about the other options you can check out our previous article on Different Types of Arduino Boards where we have compared ...

The Joystick module is similar to analog joysticks found in gamepads. In this tutorial, we will learn how to interface the joystick module with Arduino.

The analog voltage for the meter can be generated by PWM. The Arduino PWM outputs have a frequency of about 500Hz which means that the pin cycles from 0 to 5V and back to 0 again 500 times a second. A ...

The “ analogRead () ” reads the value from the specified analog pin. Arduino Uno contains a multichannel 10-bit ADC (analog to digital converter). This means that it will map input voltages between 0 ...

Little Bird Electronics posted an article about using an analog voltage reference with Arduino. This is a tool available when using an analog-to-digital converter. By setting up either an internal … ...
