This component let us to control the mosfet without a direct contact between atmega and lamp. If we have a p channel mosfet the situation was reversed.

2SK (Fuji) – N-channel MOS-FET, MOSFETs

In this case we use a halogen lamp with 16W power at 12volts.


The atmega has the PWM option, so we will chop the tension until the intensity we want. That current is calculated with this formula: You can observe if we have a switching frequency datsaheet the current is also higher.

To protect the microcontroller we use a optocoupler which has a limit of switching current. To chop the tension we will use a transistor. Such a project is detailed below: Why we have calculate this value???

The program for this project is: The wiring diagram is below: To adjust the PWM between 0 and we use a 20kohms potentiometer on analog 3 pin like in the image below:.

Of course the entire project can be made with an arduino, just mount the optocoupler on the pin 9. Because the PWM of atmega has a switching datsheet about Hz we have a datashret time around 2 ms. 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. An article about Atmega sandalone you have here.


This control is made by dqtasheet and protect the atmega from eventual defect in the part of mosfet. 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. Because sometimes we want to dim the lamp, we try with an Atmega and anothers components to reduce the intensity with a potentiometer.

August 15, admin 2. The mount base GU 10 or GU 5. To adjust the PWM between 0 and we use a 20kohms potentiometer on analog 3 pin like in the image below: 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.

That current is calculated with this formula:.

August 21, admin We use also a radiator from a PC power source. Currently you have JavaScript disabled.
