Satasheet 16W power the lamp will absorb 1. This component let us to control the mosfet without a direct contact between atmega and lamp.

Currently you have JavaScript disabled. Of course you can buy it but why not 2s,2648 make yourself one as you like homemade and have the satisfaction that you made something by yourself. To protect the microcontroller we use a optocoupler which has a limit of switching current.

The mount base GU 10 or GU 5. 2sk2468 a project is detailed below: 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. If we have a p channel mosfet the situation was reversed.

February 26, admin 5. 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:.

2SK2648-01

That current is calculated with this formula:. To chop the tension we will use a transistor. Of course the entire project can be made with an arduino, just mount the optocoupler on the pin 9.

Dagasheet the PWM of atmega has a switching frequency about Hz we have a switching time around 2 ms. In this case we use a halogen lamp with 16W power at 12volts.

The wiring diagram is below: Because sometimes we want to dim the lamp, we try with an Atmega and anothers components to reduce the intensity with a potentiometer. August 15, admin 2. Why we have calculate this value??? To adjust the PWM between 0 and we use a datasheey potentiometer on analog 3 pin like in the image below: An article about Atmega sandalone you have here.

The atmega has the PWM daasheet, so we will chop the tension until the intensity we want.

You can observe if we have a switching frequency higher the current is also higher. 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. 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.

That current is calculated with this formula: August 21, admin The program for this project is: 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.
