Materials used and their functions

555 Timer IC:

Edited with Canva.

It is used for timing and signal control. This circuit is a very important component for setting the time of 10 minutes.

Resistors (R1, R2, R3):

These resistors are used for voltage division and signal control, which helps in the timing configuration of the circuit.

Capacitors (C1, C2):

These capacitors help in holding charge and managing the timing configuration.

** LED: Diodes (D1, D2):**

A light source, which produces light by receiving electrical energy.

Potentiometer:

A variable resistor, used to control a signal or voltage.

Switch (S1):

It is used to start and stop the timer.

Battery (9V):

Used to supply power to the circuit.

Steps to make the circuit

Step 1: 555 Timer IC Connection

First, I took the 555 timer IC and marked its pinouts correctly and arranged them. Below is my interpretation of the pinouts:
Pin 1 Ground: Zero voltage of the IC.

Pin 2 Trigger: Used to trigger the signal.

Pin 3 Output: Provides the output signal.

Pin 4 Reset: Used to reset or restart the IC.

Pin 5 Control Voltage Input Pin: It helps in controlling the performance of the IC.

Pin 6 Threshold Pin: Used for timing and signal control.

Pin 7 Discharge: Pin used to discharge the capacitor charge.

Pin 8 Power Supply: Power supply pin, provides the voltage to the circuit.

Here are the pinouts of the 555 timer IC.

Step 2: Resistance and Capacitor Connection.

In this step, I connected the 555 timer IC pinouts and connected the R1 (10 kΩ) resistor to pin 4 and the C1 (0.01 µF) capacitor to pin 5. Then, I powered the circuit with a 9V battery.

Step 3: Resistance, Capacitor, Switch Connection

In this step, I connected the C2 (150 µF) capacitor to pin 7 (discharge). Then I connected pin 4 (reset) to pin 2 (trigger). Then I connected a switch to turn the circuit on/off.

Step 4: Variable Resistance, Capacitor and Diode Connection

In this step, I connected the VR (500K) variable resistance to pin 7 (discharge), which will change the timing configuration. Then I connected the R2-R3 resistance to pin number 3 output. Then I used D1 and D2 diodes to filter the signal in the circuit. After that, I connected the R4 (2.2 MΩ) resistance.

Conclusion

It took me some time to make this circuit, and through it I have successfully made a 10-minute timer using a 555 timer IC. The circuit is very effective and easy to make. Finally, I took a selfie with my hand-drawn diagram.
