Such a project is detailed below: In order to post comments, please make sure JavaScript and Cookies are enabled, and reload the page. This component let us to control the mosfet without a direct contact between atmega and lamp.

To chop the tension we will use a transistor. You can observe if we have a switching frequency higher the current is also higher.

2SK (Fuji) – N-channel Mos-fet

In this case we use a halogen lamp with 16W power at 12volts. Because the PWM of atmega has a switching frequency about Hz we have a switching time around 2 ms.

We use also a radiator from a PC power source. The program for this project is: Datashheet 15, admin 2. The mount base GU 10 or GU 5.


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. The wiring diagram is below: If you like the article click the follow button from social media to stay in touch with us! The atmega has the PWM option, so we will chop the tension until the intensity we want. 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.

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 on gate 12 volts and it is polarized lamp on.

Of course the entire project can be made with an arduino, just mount the optocoupler on the pin 9. Because sometimes we want to dim 2sk268 lamp, we try with an Atmega and anothers components to reduce the intensity with a potentiometer.


1pcs- Fuji 2SK2648 (K2648) N-channel MOS-FET Transistor

To adjust the PWM between 0 and we 2ek2648 a 20kohms potentiometer on analog 3 pin like in the image below: February 26, admin 5. 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.

To adjust the PWM between 0 and we use datawheet 20kohms potentiometer on analog 3 pin like in the image below:. An article about Atmega sandalone you have here.

To protect the microcontroller we use a optocoupler which has a limit of switching current. If we have a p channel mosfet the situation was reversed. Currently you have JavaScript dahasheet. August 21, admin Why we have calculate this value??? At 16W power the lamp will absorb 1. This control is made by light and protect the atmega from eventual defect in the part datashedt mosfet. That current is calculated with this formula:
