how to make mini multimeter

 Smart Pocket Multimeter. अब आसानी घर पर सारे electronic components को चेक करने बाला device बनाइये बहोत ही आसानी से .....



दोस्तो  आज के इस आर्टिक्ल मे हम जानेंगे कैसे हम अपने घर पर बहोत ही आसानी से  एक पॉकेट मुल्टिमेटर बना सकते है वो भी सिर्फ Rs 20 पर । इस मुल्टिमेटर के जरिये हम कोई भी एलेक्ट्रोनिक उपकरण कोंचेक्क कर सकते हाओ बहोत ही आसानी से और इसे अप चाहे rechargeable भी बना सकते है जैसे की हमने अपने विडियो मे बताया है। 



दोस्तो इस प्रोजेक्ट और डिवाइस को बना ने के लिए हुमे लेना होगा एक PVC पीपे और इस पीपे को कुछ इस्स तरह से काटना होगा जैसे ये एक चिमटी जैसे दिखे , उसके बाद हुमे लेना है एक npn transistor जिसका नंबर है BC547 इस ट्रंजिस्टर का तीन टेरमीनल्स होते है पहला emitter , base और collector , अभी हुमे एक buzzer लवना है और उस buzzer के negative को ट्रंजिस्टर के collector पिन पर सोलदेरिंग कर देना है  और बुज्जर के पॉज़िटिव को बैटरि के पॉज़िटिव पे कनैक्ट करना है उसके बाद बैटरि का नेगेटिव को ट्रंजिस्टर के emitter पिन पर कनैक्ट करना होगा और अवि लेना है एक 220ohm का resistor इस रेसिस्टर को ट्रंजिस्टर के base टेरमीनल पर कनैक्ट करना होगा इसके बाद ट्रंजिस्टर base बाले resistor से एक wire और बत्तरे के पॉज़िटिव से एक wire निकालना है जिसक्व जरिये हम कुछ भी टेस्ट कर सके ।




REQUIREMENTS :

1. BC547 NPN transistor. 2. 2 Resistor (220 ohms). 3. Buzzer. 4. LED. 5. Li-ion Battery. 6. Charging module. 7. PVC Pipe. 8. connecting Wire.

How to make talking Voltmeter at home

 Homemade talking voltmeter using Arduino   It's easy to make a simple digital voltmeter using an Arduino, Audio amplifier and Speaker It's relatively simple to use an Arduino to measure voltages. The Arduino has several analog input pins that connect to an analog-to-digital converter (ADC) inside the Arduino. The Arduino ADC is a ten-bit converter, meaning that the output value will range from 0 to 1023. We will obtain this value by using the analogRead() function. If you know the reference voltage--in this case we will use 5 V--you can easily calculate the voltage present at the analog input.   Requirement 1. Arduino uno/nano. 2. Audio amplifier. 3. Speaker. 4. 100K ohm resistor. 5. battery . Circuit Diagram  Pin mapping table for different platforms    * Platform     Normal      Inverted    8kHz timer  PWM timer  * -------------------------------------------------------  * AVR      ...

wireless electricity transmission working and its circuit diagram in the present day, electricity is treated as one ao the basic requirements of human beings. but, the cost of making electricity is high. according to the energy information records, approximately 50% of all electricity plants are contaminating coal plants. various changes in the environment have happened over the last thirty years, which are injurious to the forthcoming of this planet. to overcome this, here is a solution to diminish greenhouse gas emissions into the soil's atmosphere through are alternative power generation. one sustainable technology leading this change is wireless electric power transmission or inductive power transfer. wireless power transmission Wireless power transmission is old technology and it was demonstrated by “Nikola Tesla” in the year of 1980. Wireless transmission mainly uses three main systems such as microwaves, solar cells, and resonance, the microwave is used in...

How to make voltmeter using Arduino

ABOUT THIS PROJECT About This project is about the simple hack of voltmeter by Arduino. The main reason behind making this is from my personal experience, when I was performing one experiment in the lab, I could not find a voltmeter so I made this hack to fulfill my requirement and also I think it will help others too. Good project for beginners which uses basic concepts, yet a power full tool. While running the code, you can find the output on the serial monitor. Calculating Voltage Formula for calculating voltage: Vout = (Val * 5.0 ) / 1024.00 ; Here in these formula Val is the value that is read by Arduino as analog input, which is further multiplied by the voltage that is been supplied by Arduino and thus to get the Vout it is divided by the cycle of time that is covered after every bit to get the value. Vin = Vout / ( R2 / R1 + R2 ) By this formula we can find the Vin that will be around 0, which indirectly means we are creating ground. NOTE: Here there is no restriction on usi...
