   - The circuit is initially powered on, and the transistor (Q1) is in the "on" position. This means that current can pass through the Tesla coil's primary coil.

   - However, an unusual event occurs when the current in the secondary coil exceeds a particular threshold, often the breakdown current of an LED linked in series. The transistor's base is linked to ground, thus pulling it "down" and causing the transistor to reach a cutoff state.
   - When the transistor reaches cutoff mode, current is no longer conducted through the primary coil. This causes the magnetic field generated by the primary coil to collapse.
   - A high-voltage flyback voltage is induced in the primary coil as the magnetic field decreases. This flyback voltage discharges into the surrounding air, causing an electric arc or plasma to form.
-  - The interruption of current flow in the primary coil has an effect on the secondary coil as well. A voltage spike in the secondary coil is caused by the sudden shift in magnetic field, which might result in a high-voltage output.

   - The process is repeated indefinitely. When the flyback voltage dissipates and the current in the secondary coil falls below the breakdown level of the LED connected in series, the voltage falls below the breakdown level of the LED. This permits the transistor to return to saturation mode, turning it "on" and commencing the magnetic field accumulation.

+  * 26.04.2023
+ I began to consider which project might pique my interest. I did some preliminary research on potential future projects.
+  * 03.05.2023
+ After a lot of thought, I chose to take on the Musical Tesla Coil project as a challenge, which would reproduce musical notes using high voltage sparks as a digital input signal from an Arduino. I selected this because I enjoy combining electrical and software engineering. In order to have a starting point, I began to conduct in-depth studies into the Tesla Coil phenomenon. Furthermore, I was looking for suggestions on the appropriate sort of Tesla Coil circuit to use for the requirements of my project.
+  * 04.05.2023
+I decided to build my musical tesla coil slayer exciter circuit from scratch, so I went through the hardware components, looked at their datasheets, and calculated what materials I needed to make the primary and secondary coils (number of turns, gauge wires, and secondary coil output voltage). In case that my circuit implementation fails, I have considered a backup plan (a little music tesla coil plasma speaker).
+  * 05.05.2023
+I ordered some of the components I needed for my project and had others on hand. My progress will determine what I order later. I initially ordered
+-Arduino medium Kit from Robotlinking
+-TIP31C Transistor x2
+-IRFP460 MOSFET N-Channel x2
+-IRFP250 MOSFET N-Channel x2
+-Transistor Heat Sinks x2
+-Capacitors
+-4N35 Optocoupler x1
+-10k/47k Resistor x1
+-PVC Pipe (1 in. Diameter, 3.93 in. Length) x1
+-30 Gauge Enamel Coated Wire
+-26 Gauge Rubber Coated Wire (Solid Core)
+-Jumper Wire
+-Power Supply (home)
+-Universal PCB board
+-Servo motor x1
+-Micro- SD Card Module x1
+-MP3 player DFPlayer Mini Module x1
+-Soldering iron x1 (home)
+  * 09.05.2023
+I acquired my components and began sketching my planned circuit on paper.
+  * 15.05.2023
+Because making and testing my circuit directly would have been too dangerous, I tried it on the free SPICE simulator program (LTSPICE).
+  * 18.05.2023
+Unfortunately, after numerous experiments and simulations of various circuits in LTSPICE, something was not right and I was unable to carry out a definitive solution for my slayer exciter circuit. My proposed slayer exciter circuit used a npn bjt (TIP31C) to drive the Mosfet (IRFP460) gate.

+  * 19.05.2023
+I decided to implement my backup plan for the circuit and also considered trying an alternate means of producing music via the spark, but this time the device would accept an analog signal input.
+  * 21.05.2023
+ I began connecting the components together on a breadboard and tested their functionality.
+  * 23.05.2023
+I began putting the software design into practice.

+I completed all of the project's code implementations.
+  * 27.05.2023
+Begin assembling and testing the project for both situations with all necessary equipment (e.g., oscilloscope). They are effective!
