Currently you have JavaScript disabled. In this case we use a halogen lamp with 16W power at 12volts. Of course 2k2648 can buy it but why not to make yourself one as you like homemade and have the satisfaction that you made something by yourself.

To adjust the PWM between 0 and we use a 20kohms potentiometer on analog 3 pin like in the image below: The wiring diagram is below: You can observe if we have a switching frequency higher the current is also higher. To chop the tension we will use a transistor.

An article about Atmega sandalone you have here. The mount base GU 10 or GU 5.

To adjust the PWM between 0 and we use a 20kohms potentiometer on analog 3 pin like in the image below:. This control is made by light and protect the atmega from eventual defect in the part of mosfet. Click here 2ek2648 instructions on how to enable JavaScript in your browser.

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. Of course the entire project can be made with an arduino, just mount the optocoupler on the pin 9. August 15, datasyeet 2. That current is calculated with this formula:.

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. That current is calculated with this formula: The program for this project is: February 26, admin 5. We use also a radiator from a Xatasheet power source. August 21, admin Why we have calculate this value???

At 16W power the lamp will absorb 1. In order to post comments, please make sure JavaScript and Cookies are enabled, and reload the page. 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. Because the PWM of atmega has a switching frequency about Hz we have a switching time around 2 ms. To protect the microcontroller we use a optocoupler which has a limit of switching current.

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