Hi,
I would like to know if anyone can help me with this, I have a 24v UV light that has Shutters that need to be opened and closed as well as limit switches to show if shutters are open/closed, the motor and limit switches are all 24v, how would I be able control this unit using the Arduino uno.
I have a 24v power supply that I got with LED lights.
regards
kyle
Hello kylevanwyk1
Either use relays or MOSFET transistors.
You need what is called an H-bridge motor driver. An H-bridge allows the Arduino to run the motor in forward or reverse, which you will need for opening and closing. There are many models available and you need to choose one suitable for your motor. You know the voltage will be 24V, but you also need to know the current.
To find out the current, use a multimeter on resistance range to measure the resistance of the motor's coil. You can then work out the current using Ohm's law.
You say the limit switches are 24V, but that probably just means they are rated for 24V. You don't have to use 24V. 5V will be fine. But post some photos of the connections to the light and maybe draw a diagram of them so we can be sure. Or post a link to the tech specs of the light if you can find any.
Arduinos, motor drivers, relays, step down converters, not to mention the software; TOO complicated.
All you need are two toggle switches and two diodes.
One DPDT toggle switch for the shutter motor and one SPST switch for the light
