I feel like you are referring to Earthing(in Electrical systems) but got confused between Earthing and Grounding. Let me explain: Grounding in elect...
Not quite—a 6000-count meter doesn’t extend the 2V range to 5.999V. The range is fixed by the multimeter, not the count. In the 2V range, both 2000...
The jitter is most likely caused by power issues or signal noise. Since you're powering the SG90 servo from the Arduino's 5V pin, that might not provi...
Ok, I will make the choice of choosing between an ESP32 and ESP8266 as simple as possible for you: Price: If you check the online stores, the price...
It looks like the issue with your code is the button bouncing and the lack of state change detection. When you press the button, it may rapidly switch...
In-depth explanation of delay() VS millis() in Arduino:What is delay()?The delay(ms) function is a simple way to pause your program for a specific dur...
@sophie Fair points! The Pico is definitely a solid option, especially if you’re into Python. That said, I still think the Arduino Uno is easier f...
It’s not always safe to assume all outlets follow the same pattern, especially in older homes where wiring might have been altered over time, so it’s ...
Since you’re eager to explore, here are some Arduino UNO R4 WiFi project ideas that take full advantage of its capabilities: Beginner-Friendly Proje...
If you’re running low on GPIO pins, there are a few efficient methods you can use:Shift Registers (e.g., 74HC595) – A shift register allows you to exp...
Hey there! Yeah, those memory terms can be confusing at first. Let's break it down simply, Arduino-style. You forgot to mention an important memory ...
For a portable IoT device, Li-ion is generally the better choice because of its higher energy density and longer lifespan. It’ll give you more runtime...
I’ve found that choosing between Li-ion and Li-Po mostly comes down to what your project needs in terms of shape, size, and power demands. Li-ion pa...
@FullBridgeRectifier Thanks for clarifying this. To summarize, there’s a subtle but important distinction here between “how many counts the hardware t...
You can't directly compare the power consumption of a board with a wireless module to one without it. Naturally, the ESP32 will consume more power whe...
