| Good circuit simulation softwares- Any suggestions? | 2 Relevance | 2 years ago | TechSpark | Softwares | |
| Hello everyone, Can anyone suggest some circuit simulation software that supports both analog and digital circuits or even better, supports Arduino? I’m looking for options that are easy to use, offer a wide range of components, and possibly include PCB integration. Both free and paid versions are fine(not too costly though). Any suggestions or experiences with using such software would be greatly appreciated. | |||||
| Best practical uses of continuity function on a multimeter? | 2 Relevance | 2 years ago | LogicLab | Theoretical questions | |
| Hello everyone, I just started using a multimeter for testing circuits, and I’m particularly curious about the continuity function. I’ve used it a couple of times to check connections, but I’d like to learn more about when and where it's most useful. Can anyone share some practical examples or tips for getting the most out of this feature, especially for troubleshooting circuits and components? | |||||
| Random garbled text on Serial Monitor? | 2 Relevance | 2 years ago | sharon | Arduino | |
| Hello everyone, I'm pretty new to Arduino programming, and I’m having trouble with serial communication on my Arduino Uno. I’m trying to use Serial. Begin(9600); in my code and have matched the baud rate with the Serial Monitor, but I either get random garbled text or no output at all. I’ve double-checked the baud rate settings, but I’m still not sure what’s going wrong. Is this something common for beginners? Could I be missing something important in the code or setup? Any help on how to troubleshoot this would be really appreciated! | |||||
| Is It Safe to Control Multiple LEDs(15) Directly from Arduino Pins? | 2 Relevance | 2 years ago | Tristan | Hardware/Schematic | |
| Hello everyone, I'm working on a school project where I need to control 15 LEDs using an Arduino, and I'm considering directly connecting them to the digital/analog pins with resistors. However, I'm concerned about potential overcurrent issues. Can anyone advise if it's safe to connect all 15 LEDs directly to the Arduino pins, or should I consider alternative methods to avoid damaging the Arduino? | |||||
| Why hasn't Arduino added a USB-C port to the UNO R3? | 2 Relevance | 2 years ago | Yvette | Hardware/Schematic | |
| Hello everyone, Arduino still uses USB Type-B instead of the latest USB-C, and to me, it doesn't seem like there's a particular reason for sticking with the older port. Why haven’t they changed it? Are there specific technical or design considerations that have influenced this decision? | |||||
| Answer to: Difference Between delay() and millis() in Arduino? | 2 Relevance | 1 year ago | Admin | Programming | |
| 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 duration (in milliseconds). While using delay(), the microcontroller does nothing except WAit, effectively blocking all other code execution. Example: Blinking an LED using delay()Here’s a basic example of using delay() to blink an LED every second: const int ledPin = 13; void setup() { pinMode(ledPin, OUTPUT); } void loop() { digitalWrite(ledPin, HIGH); // Turn LED on delay(1000); // WAit for ... | |||||
| Answer to: Is It Safe to Control 15 LEDs Directly from Arduino Pins? | 2 Relevance | 2 years ago | TechTalks | Hardware/Schematic | |
| Hello Tristan, You see directly connecting 15 LEDs to Arduino pins can lead to overcurrent issues, potentially damaging the Arduino. This is because each LED draws a certain amount of current, and the combined current draw can easily exceed the maximum current rating of the Arduino's pins. Additionally, the resistors used to limit current will also dissipate power, which can overheat the Arduino or the resistors themselves. To avoid these problems, it's recommended to use LED driver such as ULN2003. These drivers and controllers can handle higher currents without overloading the Arduino pins. By employing these methods, you can safely control 15 LEDs with your Arduino without risking damage. hope this will help | |||||
| Why Does analogWrite Use a 0-255 Range for PWM? | 2 Relevance | 2 years ago | Paul | Programming | |
| Hello everyone, I'm trying to understand why the analogWrite function in Arduino requires a value between 0 and 255 for PWM (Pulse Width Modulation). What does this range actually signify in terms of how PWM works? Why specifically these values, and how does it relate to controlling the output? thank you | |||||
| Can IR Sensors Replace Ultrasonic Sensors in Most Applications? | 2 Relevance | 2 years ago | Jignesh | Hardware/Schematic | |
| Hello everyone,I'm looking into using IR (Infrared) sensors for my projects and WAnt to understand how they compare to ultrasonic sensors. Can IR sensors be used in most situations where ultrasonic sensors are typically used, except for measuring precise distances? If IR sensors can be used, what are the main drawbacks or limitations of using them instead of ultrasonic sensors? Thank you | |||||
