| Answer to: Linear voltage regulators Vs Switching voltage regulators? | 2 Relevance | 2 years 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: 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: Is Arduino still relevant in 2024? | 2 Relevance | 2 years ago | Jeffmon | Arduino | |
| ... charger that I WAs recently involved in ran into over $23,000. The unit used a PIC Microcontroller and could charge 4 batteries of all construction types. 70% of this charge WAs in the 9 prototypes that were required. The PCB engineer and the software engineer put in many, many hours. Have you seen the dollars amount an engineer commands these days? My job WAs simple. I Designed the power switching interface between the Microcontroller and the battery. An Arduino MEGA would have made this task much cheaper but we are aligned with Microchip and are ther ... | |||||
| RE: Is Arduino still relevant in 2024? | 2 Relevance | 2 years ago | Jeffmon | Arduino | |
| Hi guys "Not cost effective " is a relative term. Yes the Arduino units are bulky and relatively expensive but in some (many) cases they are the only WAy to go. Using a single chip to do what an Arduino unit can do first requires a PCB to be Designed and often several will need to be done before the Design is ready. Prototypes then need to be made and again many, then components need to be purchased along with the inevitable out of stock lines sometimes requiring a redesign all blow out to often quite large production costs. I know I Did this many times. T ... | |||||
