That current is calculated with this formula:. If we have a p channel mosfet the situation was reversed.
Why we have calculate this value??? At 16W power the lamp will absorb 1.
Because we will chop the tension datxsheet the gate of mosfet can appear a higher current, value dependent from switching time and charge of the gate. 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.

This control is made by light and protect the atmega from eventual defect in the part of mosfet. Another characteristic unlike the bipolar transistor is that the dataxheet need a tension on the gate bigger than 10 volts, we will use 12 from power source.
If you like the article click the follow button from social media to stay in touch with us! Such a project is detailed below: In this case we use a halogen lamp with 16W power at 12volts. Datzsheet adjust the PWM between 0 and we use a 20kohms potentiometer on analog 3 pin like in the image below: We use also a radiator from a PC power source.
August 21, admin The program for this project is: August 15, admin 2. Because the PWM of atmega has a switching frequency about Hz we have a switching time around 2 ms. The mount base GU 10 or GU 5.
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. To chop the tension we will use a transistor. The atmega has the PWM option, so we will chop the tension until the intensity we want.
An article about Atmega sandalone you have here.

The wiring diagram is below: You can observe if we have a switching frequency higher the current is also higher. That current is calculated with this formula: Because sometimes we want to dim the lamp, we try with an Atmega and anothers components to reduce datashset intensity with a potentiometer.
