If you want to make your very own robot you’ve got to start somewhere. The world of DIY electronics is powered by Arduino, a hardware and software community that releases customizable kits for use in a wide variety of projects. Arduino’s kits are versatile and can power complex and impressive robots, but remain simple enough for beginners to learn and build their own creations.

Right now is a great time to get into DIY electronics, because there’s a 15-course Arduino eBook bundle that’s available for a price you choose. These fifteen eBooks would normally sell for a combined price of $277.85, but if you take advantage of the Pay What You Want sale you can get them for a price you pick.

Here’s how the deal works: Pay what you want, and you’ll unlock 4 of the collection’s 15 ebooks instantly. Beat the average price paid by other customers and you’ll get the other 11 books at no extra charge.

This bundle includes Getting Started With Arduino, a walk-through of open-source electronics that comes with hands-on projects designed for beginners. Other projects include making creations with Lego, building motion sensors, designing a musical synthesizer, robots, and much more. These guides are currently on sale, just pay what you want to learn DIY electronics.

Prices are subject to change.
