Sir but it is not working based upon temperature, causally when we connect the power supply, the fan automatically starts rotation and also the bulb glowing.
@@vishalgowtham6351This is a comparator circuit using an operational amplifier Check the voltage on I.C pin-Three. Then set the voltage of I.C pin-Two .02 voltage more than pin number three. Example: if voltage ofpin-3 is 5.V, Then set pin 2 voltage to 5.02V ( use the potentiometer for adjusting)
Aapka video lajawab hua hai per Mera ismein DC rechargeable system Kiya hai voltage adjust karke Diya fir bhi wrong voltage show kar raha hai kya problem ho sakta hai
components list and circuit diagram are given in the description..😊. ( This is a simple transistor based hobby circuit for learning.. 5...10cm is the range)
Sorry about my late reply. I have checked the circuit schematic i couldn't find any mistake on it. How did you test the circuit ? On breadboard or soldering? You used the same components as I have shown in the circuit?
i checked everything and it looks clear to me, just incase i missed smth about my basics. Does the type of transistter matter I used a mosfet and some transistters
1.Please check the polarity of the photo diode. ( Anode to base and cathode to positive) (If not solved do the 2nd step) 2. Remove the photo diode and connect to the power supply. If the buzzer beeps without the photo diode, the problem may be with the transistor or wiring issue.
I have checked the polarity its correct and after removing the photodiode the buzzer doesn't beep. So what can be the issue still I am having same provlem
Can you please please please tell the type of transistor used and the capacitor used and the values of resistors used and the power supply (basically provide with a circuit diagram)
@@rakshanaggarwal4032 I am really sorry about my mistake. Actually the circuit diagram is added with the video. Watch the Full video. In the middle of the video you can see the circuit diagram and components values .

You mean on the top side? Those two jumper wires on top are connected to Supply positive. And the other two jumpers (one short and one long) are connected to Supply Negative. Thanks for watching my videos😊👍👍
I have same multimeter same model lam facing problem like above countineous beep sound on continty mode without to sorting the probes. Other parameter also not proper no physical damage on component side l checked sliders are OK plguide me thanks
