To protect the microcontroller we use a optocoupler which has a limit of switching current.

2SK2648-01 MOSFET. Datasheet pdf. Equivalent

The program for this project is: 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 dagasheet open contact the mosfet receive on gate 12 volts and it is polarized lamp on.

This control is made by light and protect the atmega from dataxheet defect in the part of mosfet.

The atmega has the PWM option, so we will chop the tension until the intensity we want. August 21, admin Of course you can buy datasgeet but why not to make yourself one as you like homemade and have the satisfaction that you made something by yourself.

If you like the article click the follow button from social media to stay in touch with us! 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. If we have a p channel mosfet the situation was reversed.

That current is calculated with this formula:.

To adjust the PWM between 0 and we use a 20kohms potentiometer on analog 3 pin like in the image below: To adjust the PWM between 0 and we use a 20kohms potentiometer on analog 3 pin like in the image below:. 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. We use also a radiator from a PC power source. Currently you have JavaScript disabled. The mount base GU 10 or GU 5. In this case we use a halogen lamp with 16W power at 12volts.

At 16W power the lamp will absorb 1. Why we have calculate this value???

In order to post comments, please make sure JavaScript and Cookies are enabled, and reload the page. To chop the tension we will use a transistor. This component let us to control the mosfet without a direct contact between atmega and lamp. That xatasheet is calculated with this formula: Such a project is detailed below: An article about Atmega sandalone you have here.

Because sometimes we want to dim the lamp, we try with an Atmega and anothers components to reduce the intensity with a potentiometer. The wiring diagram is below: February 26, admin 5.

August 15, admin 2. You can observe if we have a switching frequency higher the current is also higher.
