| 8 | Controlling DC motor speed using voltage directly is inefficient, so this circuit uses Pulse Width Modulation (PWM) to do it more effectively. A 555 timer generates a square wave where the ON time and OFF time can be adjusted using the variable resistor (VR1). When the pulse is narrow, the motor receives power for a shorter time, resulting in lower average voltage and slower speed. When the pulse is wide, the motor gets power for longer duration, increasing the average voltage and making it spin faster. The diodes around the potentiometer help control the charge and discharge paths separately, allowing smooth duty cycle adjustment. The output from the 555 timer drives a power transistor (2N3055), which acts like a switch to supply current to the motor. A diode across the motor protects the circuit from voltage spikes generated when the motor turns off. This method provides efficient speed control with minimal power loss.

| 10 | This circuit shows how an Arduino controls an RGB LED using three output pins. An RGB LED contains three internal LEDs—Red, Green, and Blue—combined in one package. In this diagram, it is a common cathode type, meaning all the negative terminals are connected together and tied to ground.
Each color pin (R, G, B) is connected to a separate Arduino digital/PWM pin through a 220Ω resistor (R1, R2, R3). These resistors limit current and protect both the LED and the Arduino.
When the Arduino sends a HIGH signal to any pin, current flows through the resistor and the corresponding LED color turns ON. By using PWM (pins marked with ~), the brightness of each color can be adjusted. By mixing different brightness levels of Red, Green, and Blue, a wide range of colors can be produced.
For example:
Red + Green = Yellow
Red + Blue = Magenta
Green + Blue = Cyan
All three = White
This is the basic principle behind color mixing in displays and lighting systems.

| 11 | A DC power supply converts AC (alternating current) into stable DC (direct current) that electronic circuits can use. This process happens in three main stages: rectification, filtering, and regulation.
First, the AC input (for example, 120V, 60 Hz) enters the rectifier circuit. Here, a bridge rectifier made of four diodes (D1–D4) converts the sinusoidal AC waveform into pulsating DC. Instead of going positive and negative, the output now stays on one side of the axis, but it still has ripples.
Next, the smoothing circuit reduces these ripples.
Finally,
the regulator circuit provides a stable and fixed DC output. An IC like the LM78xx series maintains a constant voltage even if the input fluctuates or the load changes. Capacitors C3 and C4 improve stability and reduce noise at the input and output of the regulator.
The final output (Vout) is clean, steady DC voltage suitable for powering electronic devices, with the negative terminal connected to ground.
