Flyback Driver circuit.
if the LED you are using can handle 5V, it would be okay but if not you could also make a voltage divider for the LED so it only gets 3V input.you might need to change R1 to a higher value one.look up on kirchoffs & Ohms laws.The math and how it works is explained over.
Hi! I am making a project on temperature measurements with arduino uno and thermistor. I am using the voltage divider method to determine the resistance of the thermistor, and the steinhart model for temperature calculations. However, when I tested it on a boiling water the resistance obtained by the setup where not the same on the multimeter readings, so that, instead of obtaining a temperature of 100 deg Celsius I obtained higher than that ranging from 101 deg Celsius-116 deg Celsius. Do you have any suggestions on how can I fix that?
