What is Arduino?
Arduino is an open-source electronics platform based on easy-to-use hardware and software. It consists of a microcontroller board and an integrated development environment (IDE) for writing and uploading code to the board. Arduino Boards are capable of reading inputs – light on a sensor, a finger on a button, or a Twitter message – and turning it into an output – activating a motor, turning on an LED, publishing something online.
Why Look for Arduino Alternatives?
While Arduino is a great platform, there are several reasons why you might want to consider alternatives:
- Cost: Some Arduino boards can be expensive, especially for beginners or those on a tight budget.
- Performance: Depending on your project requirements, you may need a more powerful microcontroller than what Arduino offers.
- Ease of use: Some users may find Arduino’s IDE and programming language challenging to learn.
- Features: Other platforms may offer additional features such as built-in Wi-Fi, Bluetooth, or more advanced peripherals.
