Can you connect lasers and LED's? Answered


Can you connect LED's and lasers in a series/parallel circuit with a transformer? How would the math work to figure out what kind of resistors I need? Keep in mind I am a beginner when it comes to LED's and no almost nothing about lasers. Just trying to figure this stuff out for some home projects. Any help would be amazing =)

Laser diodes tend to be VERY finicky about the drive current and voltage. Its NOT a good idea to run them just off a resistor.

Just look up "LED calculator" and there are lots of widgets out there to do the math given the configuration you are going to use. That said, you will need to know the power requirements of the lasers you are using and how that fits into your circuit and the power output of your transformer. No matter the power of the laser, use with caution.
