My project is about establishing the principle of solar power. After completing this project, you can leave it on your windowsill in direct sunlight or outside as long as it does not rain. This does not need any of the following:
- Power source
Not even a breadboard, if you have female/female jumper wires. If you want a carefree project, do this one.
Time to wire up the project! Please arrange your main components in the starting setup:
Once you have your components, set up your circuit. Connect the red (positive) wire of the first solar cell to the longer (positive) leg of your LED. You can do this with a female/female wire directly or connect with a male/female on a breadboard. I did this on a breadboard.
Connect the black (negative) wire of the first solar cell to the red (positive) wire of the second solar cell by taping them onto some sort of board (desk, concrete, plywood, etc.)
Connect the black (negative) wire of the second solar cell to the red (positive) wire of the third.
Last but not least, connect the black (negative) wire of the final solar cell to the shorter (negative) wire of your LED, and you're finished!
Repeat this pattern with however many solar cells you want to get more voltage. Remember, don't put too much voltage into a single LED! You might stress it out.
Take your LED around the house to see how it responds to different levels of light. Not working?
- Is it cloudy?
- Have you wired it up properly?
- Have you inserted the appropriate LED?
Congratulations, your project is complete! Dismantle it or leave it in a bright location to put your project to use.
