Currently you have JavaScript disabled. If we have a p channel mosfet the situation was reversed.

To protect the microcontroller we use a optocoupler which has a limit of switching current. August 21, admin Why we have calculate this value???

The program for this project is: 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. At 16W power the lamp will absorb 1.

Such a project is detailed below: This component let us to control the mosfet without a direct contact between atmega and lamp. August 15, admin 2.

Of course the entire project can be made with an arduino, just mount the optocoupler on the pin 9. The mount base GU 10 or GU 5. You can observe if we have a switching frequency higher the current is also higher. Because sometimes we want to dim the lamp, we try with an Atmega and anothers components to reduce the intensity with a potentiometer. To chop the tension we will use a transistor.

That current is calculated with this formula:. 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.

That current is calculated with this formula: Of course you can buy it but why datashet to make yourself one as you like homemade and have the satisfaction that you made something by yourself. Because the PWM of atmega has a switching frequency about Hz we have a switching time around 2 ms. This control is made by light and protect the atmega from eventual defect in the part of mosfet.


We use also a radiator from a PC power source.

The wiring diagram is below: 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.

In this case we use dafasheet halogen lamp with 16W power at 12volts. Click here for instructions on how to enable JavaScript in your browser.

To adjust the PWM between 0 and we use a 20kohms potentiometer on analog 3 pin like in the image below: The atmega has the PWM option, so we will chop dztasheet tension until the intensity we want. To adjust the PWM between 0 and we use a 20kohms potentiometer on analog 3 pin like in the image below:. February 26, admin 5.
