ESR (Equivalent Series Resistance) plays a big role in how effective a decoupling capacitor is. Low ESR capacitors, like ceramics, are great at handli...

It’s more like ROM—the kind of memory you use when you need the data to stick around, even if power is lost. Think of it like writing something on you...

I used to use the Hantek 2D72 during on-site visits — handy little device. It’s got basic scope functions, a multimeter, and even a signal generator. ...

The best way to manage real-time tasks in FreeRTOS is to carefully structure your tasks based on timing requirements, priority levels, and resource us...

If you're just starting out with Arduino and electronics, you're definitely not alone—there are some fantastic beginner-friendly resources out there t...

Yes, definitely discharge the capacitor first — especially if it's a high-voltage one. A charged cap can damage your multimeter or give you completely...

This issue is common with the DHT11 on ESP32. Here’s what you can try: Use a 10K pull-up resistor between DATA and VCC (essential for signal sta...

You're right—LoRa is impressive regarding long-range, low-power communication, and the secret behind that is how it sends data. Instead of regular rad...

ARM and AVR microcontrollers differ significantly in architecture, performance, and typical applications. AVR microcontrollers are 8-bit devices based...

Operational amplifiers (op-amps) are essentially extremely powerful voltage amplifiers. They amplify the difference between two input voltages by a ve...

An oscillator provides the clock signal that controls the execution timing of a microcontroller. Internal oscillators are built-in, cost-effective, an...

@sebastian Yeah, I get what you mean—there are definitely some exciting new boards out there! The Nano 33 IoT is super beginner-friendly, and I can se...

@ankunegi I agree that the ESP32 still offers unbeatable value under $5, especially with its built-in Wi-Fi and Bluetooth. But considering the newer R...

A diode across a relay coil is necessary to protect the control circuit from voltage spikes caused by the collapsing magnetic field when the relay is ...

I had a similar issue with my ESP32 when I first started using it. In my case, the problem was the CP2102 driver. After installing the correct driver,...
