Does Arduino AI Assistant pick parts or draw wiring?

Arduino says it can help you wire your hardware correctly, but its published descriptions focus on code and do not mention choosing parts or drawing wiring diagrams. Schematik produces a parts list, wiring diagram, and assembly steps alongside the firmware.

Is Arduino AI Assistant free?

It is available on every Arduino Cloud plan. The Free plan includes 30 interactions a month, Maker and School include 1,500, and Team and Enterprise are unlimited.

Can I use Schematik and Arduino AI Assistant together?

Yes. Use Schematik to plan the parts, wiring, and first firmware, then paste Arduino code into a sketch in the Arduino Cloud Editor if you want to keep working on it there with Arduino AI Assistant.

Which boards does each one support?

Arduino AI Assistant works on any sketch in the Arduino Cloud Editor, which supports Arduino boards and ESP-based boards. Schematik builds for Arduino, ESP32, and Raspberry Pi Pico boards and flashes supported boards from the browser.

Which is better for beginners?

If you are new to hardware and do not yet know what to buy or how to wire it, Schematik covers more of the path. If you already have a working circuit and want help with the code, Arduino AI Assistant is right there in the editor.

Schematik or Arduino AI Assistant?

Arduino AI Assistant helps you write and fix the code in a sketch inside the Arduino Cloud Editor. Schematik starts one step earlier, with the idea, and gives you the parts, wiring, pin map, firmware, and assembly steps, then flashes supported boards from Chrome or Edge.

TL;DR

Use Arduino AI Assistant when you already know the parts and wiring and want help with the code in your sketch. Use Schematik when you are starting from an idea and need to know what to buy, how to wire it, and what code to flash.

01 Schematik

Schematik is strongest when the hard part is the whole build: what to buy, how to wire it, what code to flash, and how to put the first prototype together.

02 Arduino AI Assistant

Arduino AI Assistant is strongest when the hardware is settled and the hard part is the code in the sketch you have open.

What Schematik generates

One prompt. Complete build package. Everything you need to go from idea to working prototype.

main.cpp

#include <Wire.h>
#include <Adafruit_SSD1306.h>
#include <DHT.h>

#define DHT_PIN    4
#define DHT_TYPE   DHT22
#define SCREEN_W   128
#define SCREEN_H   64

// Sensor & display instances
DHT dht(DHT_PIN, DHT_TYPE);
Adafruit_SSD1306 display(SCREEN_W, SCREEN_H, &Wire);

void setup() {
  dht.begin();
  display.begin(SSD1306_SWITCHCAPVCC, 0x3C);
  display.clearDisplay();
}

void loop() {
  float temp = dht.readTemperature();
  float hum  = dht.readHumidity();
  display.clearDisplay();
  display.setTextSize(1);
  display.setCursor(0, 0);
  display.printf("Temp: %.1f C", temp);
  display.setCursor(0, 20);
  display.printf("Hum:  %.0f%%", hum);
  display.display();
  delay(2000);
}

03 Build

Schematik

Use the browser deploy flow for supported boards or export the project files to customize on your own.

Arduino AI Assistant

Upload the sketch to your board through the Cloud Agent on Windows, macOS, or Linux

Choose the right tool

Choose Schematik if

Schematik is an AI hardware builder that turns a plain-language project description into a complete, buildable starter package for microcontroller prototypes.

You have an idea but not yet a parts list or wiring plan
You want parts, wiring, pin choices, code, and assembly steps together
You want the board and parts chosen for you
You want to flash a supported board from Chrome or Edge without setting up an IDE

Choose Arduino AI Assistant if

Arduino AI Assistant is a chat in the Arduino Cloud Editor that writes, fixes, and explains code for the sketch you have open.

You already have a sketch open in the Arduino Cloud Editor
You know your hardware and need help with the code
You want a bug in your sketch fixed or a function explained
You use Arduino Cloud for your boards, sketches, and IoT dashboards
