Yes, the 0.6 V drop you’re seeing is the meter’s burden voltage, which is the voltage lost across the DMM when it measures current. In mA mode, the me...
PWM frequency doesn’t change the basic control of speed or brightness (that’s handled by duty cycle), but it does affect how smooth and practical the ...
If your robot needs both real-time motor control and higher-level processing (like computer vision or LIDAR), I’d recommend a hybrid setup. Use a T...
There are people claim that BJTs (Bipolar Junction Transistors) are obsolete, but they continue to play a vital role in analog signal amplification du...
That's actually a great question — and definitely not a silly one. MOSFETs are often preferred over relays in switching circuits for several technical...
Both flyback diodes and snubbers are used to protect switching devices from voltage spikes caused by inductive loads, but they serve different purpose...
A watchdog timer (WDT) is a hardware timer that resets the microcontroller if it crashes or freezes. The system must periodically reset the WDT ("kick...
As you are new to electrical concepts, this explanation should be perfect for you. A transformer works by transferring electrical energy from one ci...
Cheap multimeters often compromise on quality. The models typically have poorly built dials that are prone to breaking, making it difficult to change ...
If you're looking for free simulation software, I’d recommend LTspice; however, it lacks built-in Arduino support. For a professional option, OrCAD an...
I've been an ESP32 user for a while, and honestly, I think it's still one of the best options out there! The dual-core processor makes multitasking a ...
Here's an example using a for loop to configure 8 digital pins (from pin 2 to pin 9) as outputs: int ledPins[] = {2, 3, 4, 5, 6, 7, 8, 9}; // Array ...
You are right, but if I had to choose between the two for new projects and didn't have a PICO, the PICO 2 would win in my eyes.
@sebastian Talk about being negative. It's priced at $5- $1 more than the original Pico and way cheaper than any original Arduino board. And did you f...
Hey, thanks for starting the topic. The specs on the Pico 2 are pretty impressive, especially with the dual Arm Cortex-M33 or dual Hazard3 processor...
