3. Arduino
Open-hardware platform with development boards and Integrated Development Environment (IDE).
It is very popular because their designs are open.
It allows you to interect with all kind of low-power electronics @5V: digital inputs, outputs, analog
inputs, analog outputs, PWM, communication buses, etc.
Limited processing performance. It is not a microprocessor!
Most known boards: Arduino Uno, Arduino Mega, Arduino Nano, Arduino Duemilanove, etc…

Atmega328
Uno, Nano, Mega
• 8-bit processor.
• Power consumption is small.
• Small RAM, ROM and clock speed.
• Uno has a pinout that has become a
standard.
• Works with 5V.
ATmega32U4
Leonardo, Micro
• Built-in USB interface (joysticks,
keyboards, mouse).
• Leonardo has a compatible pinout with
Uno.
SAM D21
Zero, MKR Zero, MKR WiFi 1010
• 32-bit processor.
• Zero has the same pinout as Uno.
• Highly configurable(I2C, SPI).
• Works with 3.3V.
• Ready IoT projects.
• More RAM, ROM and clock speed.
• MKR WiFi 1010 includes a ESP32.

6. Arduino IDE
Arduino’s Integrated Development Environment.
Lightweight.
Cross-platform.
Board management.
Integrated libraries.
Third-party hardware support.

8. Arduino vs. ESP32 in IoT
Arduino’s focus is directed towards Internet of Things (IoT).
MKR Series provide different connectivity options and power management.
However, Espressiff has taken a great advantage.
