Web16 mrt. 2024 · LDRs (light-dependent resistors) are used to detect light levels, eg in automatic security lights. Their resistance decreases as the light intensity increases. WebThe used PV panel generates a voltage up to 5.5 V or more. Therefore, in this project, a voltage divider circuit, which also acts as a load, is realized to adapt this voltage to the Arduino analog input which is limited to 5 V. But, you can simply use a voltage sensor to acquire the PV voltage.
