SUMMARY

The discussion focuses on converting changes in current to voltage equivalents, specifically addressing the relationship where a 50% increase in current results in a 50% increase in voltage. The user is attempting to utilize a photoresistor as an analog input for an Analog-to-Digital Converter (ADC), which operates on a voltage basis. The solution proposed involves using a transimpedance amplifier to achieve this conversion effectively.

PREREQUISITES
  • Understanding of transimpedance amplifiers
  • Knowledge of photoresistor functionality
  • Familiarity with Analog-to-Digital Converters (ADCs)
  • Basic principles of current and voltage relationships
NEXT STEPS
  • Research the design and implementation of transimpedance amplifiers
  • Study the characteristics and applications of photoresistors
  • Learn about ADC voltage input requirements and configurations
  • Explore current-to-voltage conversion techniques in electronic circuits
USEFUL FOR

Electronics engineers, hobbyists working with sensors, and anyone involved in designing circuits that require current-to-voltage conversion for ADC applications.

What's the trick to convert changes in current to some voltage equivalent?

50% increase in current --> 50% increase in voltage

Can it be done?

What I'm doing is trying to take a photoresistor and have it act as an analog input on a ADC however the ADC is voltage based. :-\
