Using these 10mm diffused LEDs is a breeze. First, find a breadboard and gently insert the LEDs into it. They're quite chunky, so it's easy to handle them. Make sure to connect them correctly according to their forward voltage. Red, yellow, and green LEDs need about 2V at 20mA current, and blue and white ones need about 3.3V at 20mA. This will help them shine at their best. When using them in your project, they can be seen clearly during the day from any angle, so they're perfect for adding some visibility. As for maintenance, keep them away from extreme temperatures and moisture. If you run into any issues, our 'Introduction to using LEDs' tutorial is there to help you out.
