What is an Electronic Circuit Project?
An electronic project is basically a circuit project built using a handful of passive and active electronic parts, by soldering them on a printed circuit broad or PCB.
The passive components are those components which do not have semiconductor material inside them such as resistors, capacitors, inductors, etc. These are called passive components because these components are not able to actively work with electricity or electrons.
On the other hand active components are those components which are internally built using semiconductor material. These components include all types of diodes, transistors, and integrated circuits.
These are called active components because the semiconductor material inside these components are able to actively work with electricity or electrons. For example diodes can rectify an AC, transistor can amplify current and voltage, whereas ICs can do similar tasks which are even more complex.

Purnendu Dasgupta says
I have a relatively high impedance voltage source that puts out +/- 200 mV depending on the pH of the solution it is exposed to. I would like to have a simple op-amp based circuit that would apply a opposing voltage to this device such that net zero current flows. I would be monitoring the opposing voltage. The overall impedance is of the order of 1 MOhm, so the short circuit current otherwise will be in nanoamps. So the need is for a zero current, constant current circuit…
Your thoughts are most appreciated…
Swagatam says
As per my understanding, you want another 200mV DC source through an opamp that could be connected with your existing 200mV?
Please let me know if I understood it correctly.
Purnendu Dasgupta says
Yes basically so. It will end up applying exactly negative of the voltage the exiting probe is generating, in the extreme +/- 450 mV.
Swagatam says
Sorry, I am still having problems understanding the configuration.
Do you want to sink the existing 200mV source to GROUND?
This can be done by shunting the source to ground with a jumper, what is the role of the op amp supposed to be here?
Jolly says
Hi boss, thanks for the circuit diagram. But I have some issues. 1, I don’t understand what kind of dieyot is D3 and I can find 48volt relay, is there any resistor I can use to convert it to either 12or 24volt relay. 2, which of the virable resistors is responsible for setting the low voltage level. Like if I want the relay to come or at either 50,40 or 30 percent. Thanks for all your response.
Swagatam says
Hi Jolly, which circuit are you referring to? Please reply under the same comment so that I can refer to the circuit diagram.
Jolly says
The 48volts monitoring relay circuit
Swagatam says
Sorry I cant find the original post where you posted you previous question.
Jolly says
Hi, I can’t find it either. But I received a circuit diagram for the 48volts battery monitoring relay. The idea was that the system is a 48volts system. The device was to monitor the 48volts when the voltage get low to like 30 or 40 percent a relay on the monitoring device should switch on and when the battery goes to full level the relay should switch off. I got a circuit diagram from you today about it but there are some things I’ll want to to look into on the drawing.

OP Verma says
I find this site very educational, thank you Swagatam and everyone.
I have the a need for the following device. Would be grateful for your help in building it.
—————————-
Light trap for Insects : the device turns on LED light automatically at dusk for 2-4 hours and attracts harmful insects in a crop field.
Device should not overcharge the battery, nor allow it to be depleted below a certain level to extend battery life.
Device should have a switch to manually turn the lights on and off.
The device should use low cost components since I need to deploy many of these devices.
The device should be essentially weather proof as it will be deployed in open field.
Thank you in advance for your help!
Swagatam says
Thank you OP,
I will try to design the circuit soon, and let you know once it is done.

I have simple mosfet wire loop security device but there is an issue the thieves can can joint the loop before the protected gadget thus making the system normal and steal the protected gadget can you design a wire loop circuit such that it activates alarm on both cutting and jointing the loop
Please i will be very thankful
Swagatam says
Hi Swasti,
If the intruder already knows the location of the trip wire and manually fixes it then there’s nothing we can do. The trip wire or the loop wire is supposed to be hidden from the intruder, if it is visible or known to the intruder then it is impossible for it to work effectively. In that case better to install a simple PIR based alarm circuit or a motion detector alarm circuit.
Swasti verma says
Thank you sir
Yes sir i have considered pir based alarm and think but In my case there in the protected area sometimes animals like dogs and cats are walking so it is possible that most of the times my PIR based alarm will give false alarms therefore it is failed
Kindly if you have another idea or circuit then please guide me i need your support please
Swagatam says
Hi Swasti,
Yes, PIR sensor or any other motion sensor will detect animals also and give false alarm, which cannot be avoided.
I think a vibration sensor can be the best option in that case, which will detect strong vibrations if an attempt is made to remove the solar panels from their installations.
Let me know your thoughts on this.
Swasti verma says
Sir you are the expert if you consider it helpful then i will be waiting for the circuit diagram of vibration sensor please make i perfect diagram so that i make the device soon
I appreciate 🙏
Swagatam says
Thank you Swasti,
According to me the first circuit from the following article will be most suitable for you:
https://www.homemade-circuits.com/simplest-sound-activated-relay-switch/
You can reduce the sensitivity of the MIC simply by increasing the value of R1 to 10k or 22k or 33k.
You can enclose the whole circuit in a plastic box and clamp it with your solar panels. If anybody tries to remove the solar panels or tries to tamper with the circuit box, the relay will be instantly activated causing the alarm to sound.
If you want more information about the circuit details or the construction you can comment under the above linked article post, I will try to sort it out for you.

Good afternoon, regarding the LEDs, I did a test with 6 LEDs but I need more light, so I ask your suggestion which would be the ideal one and regarding the battery, as you told me, it can be either solar or AC rechargeable.
I thank you for your attention and support of this important project for me. Thank you.
Swagatam says
It will be difficult for me to know how much light you need for the painting. It will depend on the size of the painting, and the number of paintings.
If 6 LEDs are not enough, you can try 10 LEDs.
I will also need to know the specifications of the LEDs you are using (Voltage and current rating)
Carlos velazquez says
Disculpe, no encuentro mi comentario donde lo podre encontrar y verificar el favor que le pedí.

The comment might have disappeared for you maybe due to the automatic clearing of the site cache, but no worries, I have received your comment and will try to design it soon.
Chibueze Nwakpuda says
I’m Chibueze Nwakpuda from Nigeria, a regular follower of your blog. Please sir, I am experiencing difficulty in building electric stove using plaster of Paris (poo) as my element base. The pop cracks when heated. Kindly advise me on the substance I can place my heating spring coil element on that cannot crack.
Thank you.
Swagatam says
Hi Chibueze, Sorry, I have no idea how the Pop cracking problem can be solved, it is beyond the scope of my expertise.
Carlos velazquez says
Good morning, I’m Carlos Velazquez. I hope you are in good health.
I’m trying to make a circuit that illuminates a painting at night for 14 hours. Starting at 6:00 p.m. and turning off at 8:00 hrs. The lighting is with LED, it must be activated with LDR when capturing the darkness outside and sending a signal with RF 433mhz and turned off when capturing the light by sending a signal to the receiver.
The transmitter must be outside the house powered by a solar cell that recharges a battery that does not consume much current and inside the receiver with a rechargeable battery, this process is daily.
For your attention, I thank you for your time and support.
Swagatam says
Good Morning Carlos,
I will design the circuit and post it as a new article. Once it is done I will let you know.
Swagatam says
Hi, how is LED lamp powered? Is it through a chargeable battery or from an AC outlet indoors. If AC outlet is available indoors then the receiver battery can be also charged through this AC source.
Carlos Velazquez says
Yes, it is a rechargeable battery that is inside the house, could you suggest which battery to use? Thank you for your time
Swagatam says
The battery voltage and Ah specifications will depend on the LED specifications. If you tell me the LED specifications, I can figure out the battery specifications.
How would you charge this battery, is it through the home AC outlet or through a solar panel?
Swagatam says
Thank you very much!
