An article about Atmega sandalone you have here. Click here for instructions on how to enable JavaScript in your browser. This control is made by light and protect the atmega from eventual defect in the part of mosfet. The 10k resistor and the transistor of optocoupler make a voltage divider, so when the transistor is polarized like a closed contact and mosfet 2sk26488 blocked lamp offwhen the transistor is blocked like a open contact the mosfet receive on gate 12 volts and it is polarized lamp on.

You can observe if we have a switching frequency higher the current is also higher. At 16W power the lamp will absorb 1.

We use also a radiator from a PC power source. The program for this project is: 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: If you like the article click the follow button from social media to stay in touch with us! To protect the microcontroller we datashee a optocoupler which has a limit of switching current. Of course the entire project can datasehet made with an arduino, just mount the optocoupler on the pin 9.

August 21, admin Such a project is detailed below: The atmega has the PWM option, so we will chop the tension until the intensity we want.

That current is calculated with this formula:. February 26, admin 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. Why we have calculate this value??? The mount base GU 10 or GU 5.

12 VOLTS LAMP DIMMING WITH ATMEGA 328

In this case we use a halogen lamp with 16W power at 12volts. Because sometimes we want to dim the lamp, we try with an Atmega and anothers components to reduce the intensity with a potentiometer. If we have a p channel mosfet the situation was reversed.

This component let us to control the mosfet without a direct contact between atmega and lamp.

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. Because the PWM of atmega has a switching frequency about Hz we have a switching time around 2 ms.
