Generally, we're talking about a maximum of 12 volts and maybe 40 milliamps with the Arduino. Not in these projects.
The Arduino is a fantastic tool for both beginners and the more experienced. When we see typical Arduino projects, the Arduino is doing fairly light lifting in terms of voltage and amperage. The Arduino itself can output 5 V, 12 V, and roughly 40 milliamps.
We thought it would be fun to explore some instances where an Arduino is being used for high-voltage projects. We're not just talking about hooking up a little bigger power supply to run an extra long strand of LEDs. We mean dangerous amounts of juice.
Join us as we take a peek at four projects that have the Arduino switching mains power -- or even spewing arcs of plasma.
