Instead of needing a special programmer or piece of software, you can copycode over like you would a file to a pen drive or external hard drive. Having worked with Arduinos for several years I was looking forward to getting to know the Pico with this book. When You push the the button with your finger, both metal terminal come in contact with each other and current starts flowing and LED starts glowing. For example, while the Pico has a max clock speed of 133 MHz, the Arduino Uno only goes up to 16 MHz. When we press the button, these terminal come in contact or simply touch each other. It provides example code to read from the onboard sensor, convert it into human-readable temperature information, and print it to the Thonny REPL. It has simple to understand syntax and extensive libraries designed to make programming various hobby development boards easier for beginners.
