🔹 Projects You Can Build with This Kit
| No. | Project Name | Components Used | Working Principle / Description |
|---|---|---|---|
| 1 | LED ON–OFF Using Push Button | 1 LED, 1 Push Button, 1×220Ω Resistor, Jumper Wires | Press the button to complete the circuit and turn ON the LED. Release to turn it OFF. Demonstrates simple switching. |
| 2 | Dual Button LED Control | 2 LEDs, 2 Push Buttons, 2×220Ω Resistors | Each button independently controls its own LED — parallel control circuit. |
| 3 | LED AND Logic Gate | 1 LED, 2 Push Buttons, 1×220Ω Resistor | LED glows only when both buttons are pressed together — simulates AND gate logic. |
| 4 | LED OR Logic Gate | 1 LED, 2 Push Buttons, 1×220Ω Resistor | LED glows when either button is pressed — simulates OR gate logic. |
| 5 | LDR Light Sensor LED (Automatic Night Lamp) | 1 LED, 1 LDR, 1×10kΩ Resistor, 1×220Ω Resistor | LED turns ON in dark and OFF in light using an LDR voltage divider circuit. |
| 6 | IR Obstacle Detector LED/Buzzer | IR Sensor, 1 LED or Buzzer, 1×220Ω Resistor | IR sensor output goes LOW/HIGH when object detected — LED or buzzer indicates obstacle. |
| No. | Project Name | Components Used | Working Principle / Description |
|---|---|---|---|
| 7 | RGB LED Manual Color Mixer | 1 RGB LED, 3 Push Buttons, 3×220Ω Resistors | Each button controls Red, Green, or Blue pin. Mixing buttons changes LED color. |
| 8 | Button-Controlled Buzzer | 1 Buzzer, 1 Push Button | Press button to activate the buzzer — demonstrates simple output control. |
| 9 | Light-Controlled Buzzer Alarm | 1 Buzzer, 1 LDR, 1×10kΩ Resistor | Buzzer turns ON in dark (or vice versa) — works as light/dark alarm. |
| 10 | Obstacle Detection Alarm | IR Sensor, 1 Buzzer | Buzzer beeps when object is near IR sensor — acts as mini security alarm. |
