Development and testing of a light dimming control using arduino uno

Introduction
Research Method
Research Results and Discussion
Conclusion

It can be done by directly measuring it using a lux meter to know the magnitude of the exposure level in a particular job. In the digital method, each PWM change is affected by the resolution of the PWM itself. The dimmer circuit uses a 12 volt power supply as a voltage source which then goes through the dc-dc converter to step up the voltage from 12 volts to 42 volts to meet the needs of the lamps used.

In this case, the lamp is HPL 32 watts and an Arduino Uno microcontroller as controller. The system consists of a power supply, for DC supply of power, DC-DC converter for the DC voltage regulation, MOSFET and voltage divider circuit for the dimming to lower the voltage to insert the microcontroller, an Arduino Uno for the main controller, a computer/laptop for coding the the microcontroller, and a High-Performance Lamp (HPL) for the light source. Thus, the illuminance will tend to be constant, since the lamp's effect is continuous.

For the voltage, a threshold value of the current is needed, in this case 0.25 amps to get a minimum voltage of 21.7 volts. The illuminance also varies depending on the distance to the perpendicular end of the board exposed to the light, as shown in Figure 13. The LDR decreased drastically as the illuminance increased, followed by hyperbolic patterns at various distances from the center .

The duty cycle increases, causing the PWM encoding and LDR to decrease linearly and hyperbolically, respectively. Finally, the illuminance decreases slightly as the distance of the measuring point from the center to the side increases.
