Daily Routine Panel
This is a 3D-printed desk device designed to track daily habits using illuminated icons and toggle switches. Each icon is engraved on the front plate and backlit with RGB LEDs, creating a clean and satisfying physical tracker for daily routines.

The enclosure assembles without supports and includes proper cutouts for toggle switches, LEDs, and internal wiring mounted on a breadboard.

🔌 Electronics Used

Toggle Switches

Micro Lever Inverter Switch ON/OFF (3A)

• 2-pin, single-channel
• Silver contacts
• Solid and clicky feel
• Used to switch the LEDs on and off

LEDs

5mm RGB LEDs – Common Anode (4-pin)

• High brightness
• Colors used: Red + Green (one per icon)
• 3V forward voltage per LED channel

Power Module

MB102 Breadboard Power Supply (5V / 3.3V)

• Powered via USB
• Provides stable 5V for LEDs and switches

Breadboard

400-point breadboard

• Used for wiring without soldering

Jumper Wires

Standard male–male jumper wires

• Used to connect switches, LEDs, power rails, and resistors

Resistors

You typically use 220 Ω resistors for 5mm RGB LEDs at 5V.
These limit the current so the LED doesn’t burn out.

🔧 Additional Hardware

🔩 Screws

To assemble the enclosure you will need:
4× M3 × 6 mm hex-cap screws (M3x6 HC)
These hold the front panel tightly to the main body.

🔧 How the Wiring Works

The circuit is extremely simple and beginner-friendly:

1. Common Ground

• All toggle switches share the same GND line.
• The center pin of each switch connects to GND using a jumper wire.

2. LED Color Control via Switch

Each RGB LED has 3 color pins: Red, Green, Blue (you use Red + Green for this project).

• The outer pins of the switch connect to
  • Red LED pin
  • Green LED pin
    When you flip the switch, it completes the circuit and lights that color.

3. LED Power (Common Anode)

• RGB LEDs have one long pin (the anode = +).
• This long pin connects to 5V through a 220 Ω resistor.

So the chain is:

5V → 220Ω resistor → Long LED pin (anode) GND → toggle switch (center pin) Switch outer pins → Red & Green LED pins 

When the switch is ON:
GND flows to one of the LED color pins → LED turns on.

4. Power Module

• The MB102 module powers everything at 5V
• Breadboard rails are used for 5V and GND distribution
• All LEDs share the same voltage rail / resistor configuration

🧩 Extra Notes

• Only one resistor is needed per LED (on the anode).
• You can swap the colors (R/G) by changing which pin of the LED you connect to the switch.
