| Answer to: Difference Between delay() and millis() in Arduino? | 2 Relevance | 1 year ago | Sebastian | Programming | |
| ... Simple tasks, like blinking an LED. millis(), on the other hand, doesn’t stop the program. It simply returns the number of milliseconds that have passed since the Arduino WAs powered on or reset. You can use it to keep track of time without pausing the rest of your code. When to use each: Use delay() if your program only has one task and you don’t mind it pausing everything else (e.g., blinking an LED with nothing else happening). Use millis() when you need your code to be non-blocking. This is essential for projects that involve multiple tasks happening ... | |||||
| Answer to: Differences Between LM358 Temperature Sensor and Thermistor? | 2 Relevance | 2 years ago | Jignesh | Theoretical questions | |
| Thermistors cost much less than the LM35 temperature sensor but require calibration due to their non-linear nature. At the same time, a thermistor is more accurate and precise(down to +/- 0.1°C) than an LM35(around +/- 0.5°C). LM35: Very easy to integrate with Arduino. You can read the output voltage directly using an analog pin, and with Simple conversion (multiply by 100 to convert from mV to °C), you get the temperature. Thermistors: While they can be integrated, they often require additional components (like a resistor for a voltage divider) and more complex calculations to convert resistance to temperature. This can make them slightly more challenging to set up. Main Differences Feature LM35 Temperature Sensor Thermistor Type Integrated circuit (analog voltage output) Resistor (typically NTC or PTC) Output Outputs a linear voltage (10 mV/°C) Resistance changes non-linearly with temperature Temperature Range Typically -55 to +150 °C Varies, but generally -40 to +125 °C Accuracy Typically ±0.5 °C or better Can be very accurate, but depends on the type and calibration Response Time Fast response time Generally fast but varies by design Ease of Use Simple to interface with Arduino (analog input) Requires more complex calculations for linearization Calibration Usually factory calibrated Often requires calibration and look-up tables for accuracy For most projects requiring precise temperature monitoring with reliable readings and ease of integration with Arduino, the LM35 is likely the best option. However, if you need the highest accuracy and can manage the additional complexity, consider using a thermistor P.S.: LM358 is an OP-AMP IC. LM35 is a temperature sensor. | |||||

| Answer to: STM32 vs Arduino: Which One is Better? | 2 Relevance | 1 year ago | Amelia | Hardware/Schematic | |
| ... MHz). STM32 microcontrollers use 32-bit ARM Cortex processors with much higher clock speeds (ranging from 48 MHz to 216 MHz or more), giving them significantly better performance for complex calculations and multitasking. When to choose STM32: If you need higher processing power for tasks like advanced signal processing, real-time data handling, or running complex algorithms. When to choose Arduino: If your project is Simple and doesn’t require high performance, sticking with an Arduino board might be easier and more straightforward. 2. Ease of Use and ... | |||||

| RE: What is the function of a flyback diode in relay circuits? | 1 Relevance | 1 year ago | Admin | Theoretical questions | |
| @avaq One thing I’ve learned from experience is how often beginners overlook the importance of a flyback diode until they encounter issues like fried transistors or glitchy microcontrollers. It’s such a Simple and cost-effective solution, but it can save a lot of time and frustration. A quick addition for anyone new to this: Always check the current and voltage ratings of the relay and choose a diode that can handle them. Common choices like 1N4007 work for most small relays, but larger relays might need something more robust. | |||||
| Answer to: Is Arduino still relevant in 2024? | 1 Relevance | 1 year ago | Sophie | Arduino | |
| I recently used an Arduino Nano in a home automation project, and it worked perfectly. The system didn’t need Wi-Fi, just a few sensors and relays. Arduino’s simplicity saved me time, and I didn’t need the extra power of an ESP32. That said, for another project involving remote monitoring, I switched to ESP32 because of its built-in Wi-Fi. Both boards have their place depending on the project requirements. I think Arduino’s strength is in keeping things Simple. If simplicity isn’t enough for your project, then yes, other boards like ESP32 might be a better fit. | |||||
| Answer to: Is Arduino still relevant in 2024? | 1 Relevance | 1 year ago | DIY Electronica | Arduino | |
| I think it’s less about “Arduino vs. ESP32” and more about picking the right tool for the job. Arduino is still fantastic for: Beginners learning electronics and coding. Quick prototypes that don’t need Wi-Fi or heavy processing power. Reliable, Simple projects like controlling LEDs or reading basic sensors. For IoT or real-time applications, ESP32 or Raspberry Pi Pico W is a better choice. But I’d say Arduino’s relevance comes from its accessibility. Many professionals started their careers with Arduino, and that familiarity keeps it in the game. | |||||

| An oscilloscope is not strictly necessary for beginners in electronics but can be incredibly helpful depending on what you are learning. For basic circuits, such as those involving LEDs, resistors, and Simple microcontroller projects, a multimeter is usually sufficient. However, if dive deeper signal analysis, timing issues, and WAveform observation, an oscilloscope becomes invaluable. | |||||
