August 21, admin To protect the microcontroller we use a optocoupler which has a limit of datasheeg current. Click here for instructions on how to enable JavaScript in your browser. If you like the article click the follow button from social media to stay in touch with us!

The mount base GU 10 or GU 5. That current is calculated with this formula:. That current is calculated with this formula: The atmega has the PWM option, so we will chop the tension until the intensity we want. Currently you have JavaScript disabled. This component let ratasheet to control the mosfet without a direct contact between atmega and lamp.

Because the PWM of atmega has a switching frequency about Hz we have a switching time around 2 ms. At 16W power the lamp will absorb 1. To adjust the PWM between 0 and we use a 20kohms potentiometer on analog 3 pin like in the image below:. 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.

We use 2s2k648 a radiator from a PC power source. February 26, admin 5. Of course the entire project can be made with an arduino, just mount the optocoupler on the pin 9. August 15, admin 2.

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. An article about Atmega sandalone you have here. 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. Such a project is detailed below: The wiring diagram is below: If we have a p channel mosfet the situation was reversed. Why we have calculate this value???


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 datassheet 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.

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. To adjust the PWM between 0 and we use a 20kohms potentiometer on analog 3 pin like in the image below: In this case we use a halogen lamp with 16W power at 12volts.

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