| Apr 2, 2018 at 1:00 | comment | added | sixter | Two TO-220's I guess. | |
| Apr 2, 2018 at 0:58 | comment | added | sixter | That'd be 5.0V. In between, I happen to have an H-Bridge motor driver IC with me. Can I drive the LED using that? | |
| Apr 2, 2018 at 0:58 | comment | added | jonk | @sixter Do you prefer a TO-220 BJT + 2 W power resistor? Or two TO-220 BJTs? It's "who cares" to me. But it may matter to you. Which would you prefer? | |
| Apr 2, 2018 at 0:43 | comment | added | jonk | @sixter That is very slow. So that means there are "lots of ways" to go. I'll write up one. Does the Arduino you have present 3.3V at the output? Or 5.0V? (I never remember.) | |
