**Assalamualaikum Everyone.** I am [@imranhassan](https://steemit.com/@imranhassan) From [#Bangladesh](https://steemit.com/trending/bangladesh)

How are you all, friends? I hope you are well; I am also well. In today's post, I will show you the process of making a 12V fluorescent lamp driver circuit. ![SC S25W2 Dibujando animé shonen.

In today's circuit diagram I will show you how to generate 230V AC output from 12V DC input using an NE555 Timer IC. This circuit uses a MOSFET and transformer, which converts our low-voltage DC power into high-voltage AC power. And the main function of our circuit today will be to run the equipment which is powered by 230V. Components used and their functions| |-| **Timer IC (NE555):** ![1.png](https://cdn.steemitimages.com/DQmdi6pKVJBrhtd4rc4L5YgmgwNhnB3J8hRbn1ayj5FN1Jq/1.png)| |-| Edited with Canva. It does the timing and signal control of the circuit. **Potentiometer (4.7K):** ![10.png](https://cdn.steemitimages.com/DQmQVyuxYtxmnbjtVQNTJpqFfeVDjAazkAzT63vdDF66C96/10.png)| |-| It is a variable resistor, with the help of which the input signal of the circuit can be controlled. **DC 12V:** ![16.png](https://cdn.steemitimages.com/DQmSTb5tG3EUsVgjgqX1VKY94HMFxChsS8sjTT2ymkJvrqG/16.png)| |-| The circuit requires a 12V DC power supply to work. **Resistors (1.5K):** ![12.png](https://cdn.steemitimages.com/DQmVskh6nocrjHAXE372P3SBfhpZRPeHCRYvoYU7pY2fgcv/12.png)| |-| These resistors control the signal and limit the current flowing in the circuit. **Step-up Transformer:** ![3.png](https://cdn.steemitimages.com/DQmRPhnBBhv8Zj21SBFC2t3siA2DVAzqM8mc5WZ3e4NhbWq/3.png)| |-| This transformer converts the 12V DC input signal to 230V AC output. **Power Transistor (BD243C):** ![8.png](https://cdn.steemitimages.com/DQmbBr11qXigDwdpK4pmnMcPqmXfLoSNRq8PQVbHYv9FTrd/8.png)| |-| It is a power transistor which amplifies the signal received from the IC and is used to supply power to the transformer. **Capacitor (100nF):** ![13.png](https://cdn.steemitimages.com/DQmbafUUf36kvvV1nfdztJHAZBM6jHg5N1i7kZkkrQ3Eu61/13.png)| |-| The capacitor helps in filtering the signal and holding the power in the circuit so that the signal remains stable. Now I am starting the step-by-step diagram drawing.| |-| Step 1: NE555 Timer IC Pinout| |-| ![image.png](https://cdn.steemitimages.com/DQmQcS7QZhd8Dc4PrDMRCM72HgVDHvTrcf5W2895y17QDZ4/image.png)| |-| First I took the NE555 Timer IC and marked its pinouts correctly. **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 charge of the capacitor. **Pin 8 Power Supply:** The power supply pin supplies voltage to the circuit. Step 2: NE555 IC Connection| |-| ![image.png](https://cdn.steemitimages.com/DQmPp7T3SfGbnFTMg4xSc85wWgnPiYSniR4qhvEGMeBGHGB/image.png)| |-| Then I connected pin 1 to ground and pin 8 to positive 12V. And also connected pin 4 to the positive line so that the IC does not reset and continues to work normally. Step 3: Resistance and Variable Resistance Connections| |-| ![image.png](https://cdn.steemitimages.com/DQmdKbBpCb5uN7AswZz9iRs6KaorA6Cx235dggJa3B39H5g/image.png)| |-| In this step, I have connected the 1.5K resistor on the left side of the circuit to pin 7 of the IC. Then I have connected the VR 4.7K variable resistor to pin 2 and pin 6. In addition, I have connected the 100 nF capacitor between pin 2 and pin 1 as a control voltage. The timing configuration and functionality of the circuit will determine that. Step 4: Output Connection and Transistor Usage| |-| ![image.png](https://cdn.steemitimages.com/DQmYfYBPN1C7f7fHWwiczoSxZPU8M9CYfRRyAZ9FCVLyGcy/image.png)| |-| In this step, I have connected the 1.5K resistor to pin 3 (output) of the NE555 IC as a control line, which provides the correct voltage to the base of the transistor, and then I have connected the MOSFET (Q1: BD243C) transistor, which amplifies the signal. Then I connected the transformer (T1), which converts the output signal to 230V AC. Conclusion:| |-| ![image.png](https://cdn.steemitimages.com/DQmQ7hRvCypFLvj2K8yqPZ9fRdPmqdsQ6XAZ4h4VzKZir45/image.png)| |-| This 12V fluorescent lamp driver circuit is made using an NE555 timer IC, which is a simple and effective lamp driver circuit. It uses a transistor (BD243C) and a transformer to convert 12V DC input to 230V AC output. And as per the community guidelines, I took a selfie with my hand-drawn raygram and wrote my username and community name.
