The Maker Uno RP2040 supports Arduino, Micropython, and CircuitPython programming, but in this review, we will be focusing on the former. So the first step is to download and install the Arduino IDE ...

PWM pins work the same way across all Arduino boards, so you don't need to go out of your way to buy a Mega if you already have a board supporting PWM. On the Uno, Nano, and Mini, the PWM pins are ...

Both the Arduino Nano and Uno can be powered via their integrated USB connectors. This automatically supplies regulated 5V power to the board, allowing you to use any USB-supported power source ...

I’m still wondering what is the use of the trick. Most µC these days use a DC/DC to convert from whatever source voltage to the 3.3V or 1.8V they need.

Using this trick, we’ll be able to realize this project with only 20 I/O pins, which would have been impossible if we had connected an LED to each pin, as we’d have needed 64 pins and — more than our ...

ArduPico with Raspberry Pi Pico board. WisdPi ArduPico is an Arduino UNO-shaped baseboard designed for the Raspberry Pi Pico and compatible boards that enables makers to reuse most 3.3V Arduino ...

This is confirmed by the fact that the pin numbering on the Arduino schematic matches the pin numbering on the datasheet. In fact, even the label names partially match but the GPIO numbering is ...

The connection between Arduino and Ethernet modules are made as shown in the circuit diagram. Connect pin 5V and GND pins of Arduino Nano to +5 and G pin of Ethernet Module respectively (These ...

It comprises four HC-SR04 ultrasonic sound sensors (SEN1-SEN4), a four-channel relay board (RM1), and an Arduino Uno board (Board1). Fig. 1: Circuit diagram of the touchless switchboard The ...
