| Answer to: As a beginner why do I need an Oscilloscope? | 1 Relevance | 2 years ago | Anju | Equipments | |
| 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. | |||||
| what is "Display count" in a multimeter? | 1 Relevance | 2 years ago | Daniel | Equipments | |
| I’ve been using a multimeter for a long time but never really thought about the term "display count." Lately, I’ve come across it in some tutorials, but I didn’t quite understand what it means. Can anyone explain it in Simple terms? | |||||
| Answer to: Why Use a DC Motor Controller Instead of a Potentiometer? | 1 Relevance | 2 years ago | LogicLab | Circuits and Projects | |
| Simple. A potentiometer is a resistor, so when the current passes through it, it results in power loss and heat, making it highly inefficient. A DC motor speed controller, on the other hand, uses components and techniques that minimize this loss and increase the overall efficiency. | |||||
| Good Arduino IoT projects for a beginner? | 1 Relevance | 2 years ago | cooper | Arduino | |
| I'm currently studying electronics engineering and have been assigned a project based on Arduino IoT. Since we haven't been taught much in this field, I'm looking for Simple yet educational project ideas suitable for a student-level Arduino IoT project. Projects involving sensors, microcontrollers, or cloud integration would be ideal. | |||||
| RE: Is ESP32 the Best Microcontroller Board of All Time? | 1 Relevance | 2 years ago | Amelia | ESP32 | |
| There's a Simple fix for that. Just take two half-size breadboards ->snap one power rail from each - > insert the ESP32(one side of pins on breadboard A and the other side on breadboard B) | |||||
| RE: Is It Safe to Control 15 LEDs Directly from Arduino Pins? | 1 Relevance | 2 years ago | Admin | Hardware/Schematic | |
| 1. Yes you can. But then you have to turn ON only one LED at a time. 2. It is Simple. If each LED consumes 12mA we get, total current= 12X15 = 180mA, which is below the maximum rating. Now resistor value = 5V/12mA = 416 ohms. | |||||
| Why Use a DC Motor Controller Instead of a Potentiometer? | 1 Relevance | 2 years ago | hobart bess | Circuits and Projects | |
| Hi everyone, I'm currently working on a project that involves controlling the speed of a DC motor. I understand that a potentiometer can be used to control the speed of a motor by varying the resistance, which in turn adjusts the voltage supplied to the motor. Given this, I'm curious about the need for dedicated DC motor controllers. Why should I consider using a separate motor controller when a Simple potentiometer seems to achieve the same result? I'd appreciate it if someone could explain the advantages or scenarios where a DC motor controller is preferred over a potentiometer for speed control. thank you | |||||
