This component let us to control the mosfet without a direct contact between atmega and lamp. If you like the article click the follow button from social media to stay in touch with us!

1PCS- FUJI 2SK (K) N-channel MOS-FET Transistor – $ | PicClick

Of course the entire project can be made with an arduino, just mount the optocoupler on the pin 9. The 10k resistor and the transistor of optocoupler make a voltage divider, so when the transistor is polarized like a closed contact and mosfet is blocked lamp offwhen the transistor is blocked like a open contact the mosfet receive catasheet gate datawheet volts and it is polarized lamp on.

February 26, admin 5. You can observe if we have a switching frequency higher the current is also higher.

That current is calculated with this formula:. Because we will chop the tension from the gate of mosfet can appear a higher current, value dependent from switching time and charge of the gate. Currently you have JavaScript disabled. The program for this project is: To protect the microcontroller we use a optocoupler which has a limit of switching current.

August 15, admin 2. Why we have calculate this value??? To adjust the PWM between 0 and we use a 20kohms potentiometer on analog 3 pin like in the image below:. Click here for instructions on how to enable JavaScript in your browser.

That current is calculated with this formula: The wiring diagram is below: Because sometimes we want to dim the lamp, we try with an Atmega and anothers components to reduce the intensity with a potentiometer. If we have a p channel mosfet the situation was reversed. The mount base GU 10 or GU 5. We use also a radiator from a PC power source.

August 21, admin Another characteristic unlike the bipolar transistor is that the mosfet need a tension on the gate bigger than 10 volts, we will use 12 from power source. At 16W power the lamp will absorb 1. The atmega has the PWM option, so we will chop the tension until the intensity we want. In this case we use a halogen lamp with 16W power at 12volts.

An article about Atmega sandalone you have here. Of course you can buy it but why not to make yourself one as you like homemade and have the satisfaction that you made something by yourself.

Such a project is detailed below: To adjust the PWM between 0 and we use a 20kohms potentiometer on analog 3 pin like in the image below: This control is made by light and protect the atmega from eventual defect in the part of mosfet. Because the PWM of atmega has a switching frequency about Hz we have datasheef switching time around 2 ms.
