Hi all. I have LED strip with Positive and Negative wiring. how do i connect it to EZ so that i can turn of the LED as and when i like through EZ B controller?
If it's 5V, you would connect the Positive to one of the PWM pins and the Negative to the corresponding Ground. Add a SET DIGITAL control in ARC and you're good to go.
If it needs more than 5V, I'd use a separate power supply and switching transistor to turn it on and off.
That being said, might I humbly recommend a classic NPN transistor like a 2N3904 or PN2222? These days the transistor prices have come down to around $0.15 in 100 lot quantities.
Transistors are great for controlling LEDs strips, relays, and more! Personally, I would much rather see motor drivers being put to good use on robot gear motors rather than replacing a simple NPN transistor
For higher current applications (like a long LED strip) check out the TIP series, I know Will is using a TIP120 to control LEDs in his latest robot project (Gar). MOSFETs would work too but they are a bit more involved than transistors.
I wonder if there is such a transistor module exists out there in the wild that has terminal blocks and jumpers on it? If not, it could be a good side project for someone to create..........
