Hi, im working on creating a step counter using piezoelectric disks. The idea is that I want to use the disks as sensors and be able to read their voltage and current values with an Arduino Uno. Im also using a voltage sensor, the sensor that will be used is an ACS712 that can detect the flowing...

Hi everyone! I'm currently working on a digital alarm clock project and have used a website for reference: (https://bestengineeringprojects.com/digital-clock-with-seconds-and-alarm-time-display/) However, I've made some modifications, such as removing the transformer and some diodes. I've added...

I have a Samsung 60" TV Model code UA60J6200AWXXY. The problem was I plugged a multi USB power board into it and as soon as I did the TV went off and I could smell something burnt. Removed the back cover off the TV after unplugging power of course. Have found a circuit that I think is what burnt...

Hello, recently my 1994 range's oven control board died and rather than replace the entire range, I figure I would find a way to power the oven's bake element by designing/building a (simple?) circuit. I have verified that the "bake" element in the oven works (drawing 13 amps at 250v AC) and the...

I don’t know where this needs to go so I put it in general. I think I need a circuit to control a 6v motor with a on/off switch. I assume it would be 1) battery 2)switch 3)circuit 4)motor. I think I need a circuit that will run a motor for 1-3 seconds then stop for roughly 20 seconds then...

I have bought this Delay Relay module off of amazon. I am using it to make a circuit that will act as a latching relay with a delay for a 12V power source. The circuit should work as follows: There is a switch to activate the relay. When activated, the relay will remain on until the 12V power...

So im trying to make a combinational lock in proteus. One of the issue i've come across is one of my button which is labelled "reset" output high even if its not press but when I connect a logic probe to the line, the cable becomes normal. The second issue is there is a sequence detector that...

A sensor works by outputting a voltage of -400mV to +400mV with a impedance of 1M Ohm. a. Design and simulate a circuit that only uses active components, such as an in the form of an OP-AMP so that the output reads 0V to 5V. Create the circuit in LTspice. Can anyone help me with this topic...

Hey there! I'm diving into a fun project and trying to design a digital alarm clock. I've been scouting the web for inspiration, hoping to find a simple design that I can tweak a bit. The thing is, a lot of the projects out there use transformers, Arduinos, or dive deep into programming with...

Hi All, I want to turn a rudder like mechanism and currently I use DC motor and polarity to turn it left & right. But It has a limitation that it can cannot be positioned in between. Now I want this extra position to be included. So thinking about a servo to achieve three positions ( left - 0...

Okay so, currently wanting to set up a test for some rechargeable batteries, and developing a lower power mode for a system. The goal is to connect fully charged batteries to my devices to see how much current they actually drain. I have an estimate how long they should last, but its not exact...

Design a circuit that can convert an analog voltage signal into a digital representation using an analog-to-digital converter (ADC). The input voltage range is from 0V to 5V, and the desired resolution of the ADC is 10 bits. Assume a single-ended input configuration.

Hello everyone I wanted to share with you the design of a 2-layer full GNSS board that I have recently developed using Direct RF sampling architecture. The board consists of several blocks, each equipped with SMA input/output connectors, as well as an SMA connection between VCC and GND to check...

My electrical engineering experience is minimal and in the general section as the background. I have one of those Chinese PCB boards that can take a 5V and 12V input on the same solder pad to run the whole device and also have a Type-C input. The maximum input on that device is 24V. I'm using...

Hi Everyone I have designed simple P-Channel MOSFET Circuit! it works well. However, when low Source power is applied(1V), glitch occurs in the output signal. I tried R,L,C component, But it didn't work What can I do to get rid of this? Circuit...

I'm searching for any videos which explain and show me how to answer questions like this, as I am unable solve this question.

Hi, this is the functional block diagram of a hall sensor IC. Can anyone please explain what is the purpose of these schmitt trigger followed by another trigger? Is single trigger cannot be able perform the function required?

I have a solar pane that gives about 12 volt and 120 mah and I want to make a 3.7 v battery charger. I dont have a voltage regulator I just have transformers, resistors and capacitors ect. and I dont have a much knowledge about electronics. Please can you send a circuit? Thanks.

Please help me to understand this circuit about analysis voltage each point and how to calculate time charge and discharge time on triangle signal. If use Op-Amp NJM2904C Thank you.
