    Looking for a remote job opportunity at Electronics Lab

    Hi everyone, I am Rifat. I hold a B.Sc. degree in Electrical and Electronic Engineering. Then did jobs at different companies from 2011 to 2020. My longest tenure was with an online store that sold electronic components and had R&D facilities of its own. The company did similar to what SparkFun...

    Short range cat detector

    OK, if you use SONAR, IR, PIR etc, the system will not be able to determine if it's a cat or person or an object. If that is not the headache, you can use HCSR04 or PIR sensor. Either way it will work. You can interface multiple sensors with an Arduino...

    Electronics-lab?

    I have been using this forum for a long time, and in my previous answer, I only shared what I saw. I have noticed the merge long ago. If I unintentionally said something offensive, I apologise.

    Electronics-lab?

    Yes, electronics lab merged with MakerPro last year. The name MakerPro does not exist anymore. It also took me some time to understand what happened when I first tried to access MakerPro after the merge. Anyway, admins and members are still the same. So, you can post questions without any...

    What is the best alternative to Proteus?

    I have used tinkercad for arduino-based simulation. But can we use that for simulating ordinary MCUs like Atmega32? In proteus, we can upload the .hex file and simulate. Is it possible with tinkercad too?

    Small circuit design

    I think you should use a heat sink for LM317.

    IR Spectrometer Project: Is This Project Within My Reach?

    A home-made grating can work in mid-infrared. You do not need nanometer-scale slits for spectral resolution. Resolution depends on illuminated grooves and optical geometry. The main difficulty is obtaining a suitable mid-infrared detector.

    Diagnosing my failed CNC controller

    Your PSU likely shuts down under load because of a fault. Test the PSU unloaded by disconnecting the controller entirely. If the voltage stays stable, the controller is faulty. If the voltage collapses, the PSU itself is bad. Measure resistance controller +V to ground for shorts. A low reading...

    Arduino & DFPlayer mini noise.

    Breadboards create noise. Long wires act like antennas. NeoPixels add sharp current spikes. These spikes disturb the DFPlayer power line. The result is clicks and hiss. A stable layout helps a lot. A small example is here: https://www.pcbway.com/project/sponsor/Arduino_With_Neopixel.html. Give...

    Electronics seems like magic!

    It’s not really an exaggeration . With just a few basic components, you can build almost anything in electronics. In analog circuits, the resistor, inductor, and capacitor form the foundation. By combining these, you can create filters, oscillators, and amplifiers — and when you add active...

    Wiring up a Y90L-2 motor

    Connect Line (Live) to the U1/main-winding terminal, Neutral to the U2, and Earth to the motor frame if only two terminals are present. If four wires, use the multimeter to identify which pair is the run winding (low resistance) and which is the start winding (higher resistance); put the 50 µF...

    Seeking Advice on PCB Design Issue: Trace Width and Thermal Problems

    Your trace width isn’t the real issue here — at 0.3 A, even a 0.5 mm trace only dissipates a few milliwatts, so the warmth you’re feeling is almost entirely from the LDO. The 1117-3.3 is dropping 1.7 V at 0.3 A, which means it’s burning about 0.5 W as heat. On a small board with a limited copper...

    Not Understanding Arduino useage versus traditional Electronics useage in Devices.

    Arduino is not always the best option if you think about price and space. Moreover, Arduino alone cannot do any work. Arduino needs to be integrated with relays, transistors, diodes, etc. Without knowing basic electronics, it's not possible to understand how these components work. We have many...
