| Answer to: Can an oscilloscope measure high DC voltage around 100V? | 2 Relevance | 1 year ago | Admin | Equipments | |
| If you need to measure around 100V DC with an oscilloscope, here’s what to keep in mind: Oscilloscope Limit: Most scopes have a max input rating of ±300V. Exceeding this can damage the scope. Use the Right Probe: Use a 10× probe rated for at least 300V. This ensures the oscilloscope only sees 10V when measuring 100V. Avoid using 1× Settings to prevent damage. Stay Cautious: If you’re unsure, double-check the probe’s rating and make sure it’s securely Set to 10×. For higher voltages, consider a 100× probe. Always know your scope’s and probe’s specifications. If in doubt, don’t risk it without confirming your Setup is safe. | |||||
| Answer to: Linear voltage regulators Vs Switching voltage regulators? | 2 Relevance | 1 year ago | Admin | Theoretical questions | |
| ... the more energy is WAsted. But they are super easy to use—just a few capacitors and you're good to go. Perfect for quick projects where you don’t need high efficiency. Switching regulators (like the LM2596) switch the input voltage on and off at high speeds, and use inductors/capacitors to store and release energy efficiently. Because of this, they are highly efficient—usually 80% or better. This makes them a great choice for battery-powered projects or situations where you need to drop a lot of voltage without WAsting power. But they’re a bit more complic ... | |||||
| Answer to: How to identify LED terminals? | 2 Relevance | 2 years ago | Sebastian | Theoretical questions | |
| Hi Aiden, To identify the anode and cathode of an LED, start with a visual inspection. Typically, the longer lead is the anode, and the shorter one is the cathode. If this method is not possible, another helpful visual indicator is the presence of a flat spot on the LED’s rim, which marks the cathode. If the internal structure is visible, the larger metal piece (die) inside the LED is connected to the cathode. If visual cues are unclear, electrical testing can be performed. Using a multimeter Set to diode mode, place the probes on the leads; a reading will indicate that the anode is connected to the positive probe. Alternatively, you can connect a battery and resistor, attaching the positive terminal to one lead. If the LED lights up, the connected lead is the anode. hope this will help | |||||
| 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. | |||||
| RE: Difference between 180° vs 360° servo motors and how to control them with Arduino | 2 Relevance | 2 years ago | Admin | Hardware/Schematic | |
| @Yvette Inside a standard servo motor, there's a potentiometer connected to the output shaft. This potentiometer provides feedback to the control circuitry about the current position of the shaft. The control circuit compares the desired position (set by the PWM signal) with the current position (measured by the potentiometer). It adjusts the motor's position to match the desired position, typically within a range of 0 to 180 degrees. Continuous rotation servos do not have a potentiometer for position feedback. Instead, the feedback loop is removed or altered so that the motor can spin freely. The control circuitry is modified to interpret the PWM signal in terms of speed and direction rather than position. A neutral PWM signal typically stops the motor, while varying the PWM width in one direction causes forward rotation, and in the other direction, reverse rotation. | |||||

| ... rotation. As they can rotate continuously in either direction. To control a servo using Arduino, you must first install the servo library. Yes, both types can be operated using this library. Then upload this code: 1) For positional servo first: #include <Servo.h> Servo myservo; // create servo object to control a servo void Setup() { myservo.attach(9); // attaches the servo on pin 9 to the servo object } void loop() { myservo.write(90); // Sets the servo position to 90 degrees (middle) delay(1000); // WAits for a second ... | |||||
