Photodiode Amplifier for Visible Light Using OPA381 – Arduino Nano Shield

Photodiode Amplifier for Visible Light Using OPA381 – Arduino Nano Shield

The project presented here is a photodiode amplifier for visible light. The output voltage of the circuit increases linearly with light intensity. Low-cost BPW34 photodiode is used as a light sensor and OPA381 op-amp as an amplifier. OPA381 is a transimpedance amplifier that converts...
