Is it possible to use a mosfet relay module to switch the lumen led on and off optionaly dim i am using a 20W smd led and the relay module shown in this link

[image] Angelo Rison K: i want to just on and off the light PWM dimming is not necessary for me now so i want to use that MOSFET module that i given in the first response to control my light like you did with blue robotics lumen light Our Lumen includes a controller PCB internally that transl…

Easy answer: Yes I use Solid State Relays on a lot of automation products that I need to control higher voltages / current than what I can source with my microcontrollers etc.

Hi @angelorisonk , It’s not clear to me what you’re asking. Our Lumen Lights can be switched on/off by pulling the signal wire high or low, and it would be roughly equivalent to tie the signal wire to the power wire and then use a relay to connect/disconnect the power, but for progressive (dim) bri…

Assuming you’re using the MOSFET as a switching device, it is possible to control the LED brightness by providing a PWM signal that you change the duty-cycle of (i.e. rapidly switch the signal voltage between its high and low levels over time, where the proportion of high time determines how bright …

One clarification @angelorisonk - The PWM outputs from ArduSub are servo style, NOT traditional PWM. This means a pulse is send that varies between 1 and 2 milliseconds, every 20 milliseconds. As @EliotBR mentioned, you could adjust this duty cycle, but doing so may affect all connected devices th…

Thank you for your assistance. I’ve decided to proceed with fabricating Blue Robotics lumen PCB design, as I believe it will allow me to dim the light more efficiently without encountering any issues. However, I have a question regarding the use of a 12V, 20W SMD LED: Will I need to make any adjustm…

[image] Angelo Rison K: Will I need to make any adjustments on the programming side to regulate the voltage, or is there something specific I should do to ensure proper operation? I wasn’t involved in the design of our driver , but it is apparently set to run up to 2 amps , so if your LED is in…

mine is approx 1.7 amps only should i increse the resistance value?

As mosfet is a voltage controled device by varying voltage we can control the brightness right is it possible to use with autopilot?
