The atmega has the PWM option, so we will chop the tension until the intensity we want.
2s2k648 To chop the tension we will use a transistor. 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.
12 VOLTS LAMP DIMMING WITH ATMEGA 328
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. An datasjeet about Atmega sandalone you have here.
In this case we use a halogen lamp with 16W power at 12volts. The wiring diagram is below: This component let us to control the mosfet without a direct contact between atmega and lamp. Why we have calculate this value???

We use also a radiator from a PC power source. If we have a p channel mosfet the situation was reversed. This control is datasneet by light and protect the atmega from eventual defect in the part of mosfet.
Because sometimes we want to dim the lamp, we try with an Atmega and anothers components to reduce the intensity with a potentiometer. At 16W power the lamp will absorb 1.
Of course you can buy it but why not to make datasheett one as you like homemade and have the satisfaction that you made something by yourself. 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 To adjust the PWM between 0 and we use a 20kohms potentiometer on analog 3 pin like in the image below: Of course the entire project can be made with an arduino, just mount the optocoupler on the pin 9.
The mount base GU 10 dahasheet GU 5.
Because eatasheet PWM of atmega has a switching frequency about Hz we have a switching time around 2 ms. February 26, admin 5. Such a project is detailed below: If you like datashset article click the follow button from social media to stay in touch with us!
You can observe if we have a switching frequency higher the current is also higher. To adjust the PWM between 0 and we use a 20kohms potentiometer on analog 3 pin like in the image below:.
