TL;DR

Use Schematik when you want to create the project and build it physically. Use Wokwi when simulation, firmware behavior, or virtual debugging is the main job.

01 Schematik

Schematik is strongest when you want the first physical version of an idea and need the build material around it, not just a place to run firmware.

02 Wokwi

Wokwi is strongest when you need a capable embedded simulator, especially for checking firmware behavior without physical parts on your desk.

What Schematik generates

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

#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();

01

Place ESP32 on breadboard

Spanning the center gap, USB port facing outward.

02

Wire DHT22 power

Connect VCC -> 3.3V rail. Connect GND -> ground rail.

03

Wire DHT22 data pin

Connect DATA -> GPIO 4 on the ESP32.

04

Connect OLED display

SDA -> GPIO 21 · SCL -> GPIO 22 · VCC -> 3.3V · GND -> GND.

05

Double-check connections

Verify all wires match the diagram before powering on.

06

Flash and run

Click Deploy in Schematik and the project is ready.

How the workflow differs

01 Describe

Schematik

Tell Schematik what you want in plain English, then review the proposed parts, wiring, and pin choices.

Wokwi

Create a virtual embedded setup with parts from the library

02 Review

Schematik

Review generated source code, wiring diagrams, pin assignments, parts, and assembly guidance.

Wokwi

Run and debug firmware against virtual hardware online

03 Build

Schematik

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

Wokwi

Validate firmware behavior before committing to physical parts

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 want an idea turned into a complete starter project
  • You need real-world wiring and assembly guidance
  • You want code and build instructions in one workflow
  • You are moving from software thinking into physical hardware

Choose Wokwi if

Wokwi is an online embedded systems simulator with VS Code integration for running and debugging firmware virtually.

  • You want to simulate firmware and virtual hardware online
  • You do not have every component on hand yet
  • You need simulator-oriented debugging tools
  • You want VS Code integration for embedded development

Feature-by-feature

Core jobDifferent jobs

Schematik

Generates a buildable hardware project from a plain-English description of what you want to make.

Wokwi

Simulates embedded hardware projects in the browser. Run firmware without physical boards.

Hardware relationshipDifferent jobs

Schematik

Aims at physical assembly and flashing real boards. The output is something you build.

Wokwi

Runs projects against virtual boards and components. Great for testing before buying parts.

In scope

What Schematik does

  • You want an idea turned into a complete starter project
  • You need real-world wiring and assembly guidance
  • You want code and build instructions in one workflow
  • You are moving from software thinking into physical hardware

Out of scope

Where Wokwi is better

  • Simulation is not the primary Schematik workflow today
  • Limited board family coverage compared to dedicated simulators
  • Wokwi has the advantage today for VS Code and CI simulation workflows
  • Virtual debugging and WiFi simulation are Wokwi strengths today

Schematik or

Fritzing

Builder or documenter

Fritzing is great when you already have a circuit in your head and want to draw it clearly. Schematik helps before that point - you describe the thing you want to make, and it gives you a buildable starter project with everything you need to start assembling.

Schematik or

Tinkercad

Physical builder or virtual sandbox

Tinkercad Circuits is friendly, visual, and useful for learning how circuits behave in a browser. Schematik is more direct about the physical build - you say what you want to make, and it gives you a complete starter project you can wire up at your desk.
