About this app

Robot Maker Toolkit is the offline field guide for anyone building with Arduino, ESP32 and Raspberry Pi Pico. Wiring, pinouts, ready-to-use code and the calculators you actually need — all on your phone. No internet, no account, no sign-up.

Whether you're wiring your first sensor or debugging a robot at 2 a.m. with no Wi-Fi, every connection is laid out clearly and checked against manufacturer datasheets.

WHAT'S INSIDE

⚡ Modules & sensors
Colour-coded wiring diagrams and connection tables for UNO, ESP32 and Pico — IMUs, ultrasonic distance, temperature & humidity, OLED & TFT displays, motor drivers, real-time clocks, RF, GPS and many more.

📌 Board pinouts
Colour-coded pinout diagrams plus a full pin reference for UNO R3, UNO R4 WiFi, Nano, Nano ESP32, Mega 2560, Leonardo, ESP32 DevKit and Raspberry Pi Pico — with the gotchas called out: 5 V-tolerant pins, ESP32 strapping pins, and PWM / I2C / SPI capabilities per pin.

🧩 Shields
Pin maps and usage notes for popular shields: Motor Shield, 1602 LCD Keypad, Ethernet, CNC, Data Logger, 4-relay and joystick shields.

🧮 Maker calculators
Resistor colour-code decoder, Ohm's law, LED series resistor, voltage divider, battery life, WS2812 power budget, RC filter, 555 timer, PWM-to-voltage, resistors in series/parallel, map() range conversion and more.

📋 Copy & share code
Every module ships with a tested example sketch you can copy to the clipboard or share straight to the Arduino IDE in one tap.

WHY MAKERS LIKE IT

✓ 100% offline — works on the bench, in the field, anywhere
✓ Accuracy first — wiring verified against datasheets, with safety warnings for voltage levels and risky pins
✓ No account, no sign-up, no clutter
✓ Small download, fast and clean

Spend less time searching forums and datasheets, and more time building. Robot Maker Toolkit keeps the reference you need one tap away.

What’s new

New board: ESP8266 NodeMCU (ESP-12E) — full pinout reference, alongside UNO, ESP32, Pico, Mega, Nano and the rest.
Fixed: the display now draws correctly edge-to-edge on recent Android versions.
Fixed: Unlock Pro no longer offers a purchase it can't complete, and "Restore purchase" says what it found instead of appearing to do nothing.
Updated for Android 16 and the current Google Play requirements.
