Electronic Dimmer Circuit Remote with PIC16F628

PIC16F628 microcontroller realized with remote controlled dimmer circuit on, off and lamp brightness reduction, elevation controls, the control uses the philipos rc5 protocol.

In the remote controlled dimmer circuit, instead of the Triac BT137F used for load control, higher power control can be achieved by using a stronger triac. Additionally, the 220v/5v regulated part of the circuit can be used in different projects where the pic16f628 supply is directly regulated by 220v without a transformer. PIC16F628A software is prepared with pic assembly source .asm code, schematic and printed circuit.

Remote Controlled Automatic Table Lamp Dimmer

It dims or dims automatically between two preset levels, or you can manually control all lamps with the remote.

PIC16F628 Dimmer Features

• Remote control operation
• Uses pre-programmed commercial remote control
• Soft start on and off control for long lamp life
• Fast and slow dimming and dimming control
• Automatic dimming and throttling
• Programmable minimum and maximum dimming levels
• Programmable auto dim rate
• The dimming level and dimming rate maintain even after a blackout
• Remote control confirmation indicator
• Auto dim indicator
• RFI suppression
• Four remote control codes available

This multi-featured Auto Lamp Dimmer circuit provides full control with an infrared remote control.

Wall-mounted lamp dimmers (i.e. lamps controlling fixed lamps in homes) are common and provide an excellent effect for adjusting brightness levels according to the situation.

However, it is not very common to find a dimmer for a table lamp or other portable lamp. But these lamps can also be dimmed.

For example, you might want to dim the lights in your living room, and you can do this with the dimmer that controls the main ceiling lights. Until now, you could only turn other lamps on and off.

For a home theater room, it is important to dim the auxiliary lights if the full visual impact of the large screen is to be realized.

As a night light, the Auto Lamp Dimmer can be set to slowly dim from full brightness (or a dimmed brightness) to a preset level over an extended period of time.

The slow dimming function is ideal for use in a nursery. It provides such a slow reduction in light over a period of time that kids won’t even notice before they fall asleep!
