Your circuit is almost good, except the LDR/VR1-R2 positions which must be swapped to enable the MOSFET to turn off during daytime. Here’s the corrected circuit diagram which you can implement: If you could tell me the specifications of the LED then I can calculate the LED series resisto...
The maker notes that the device first trains a cat to figure out where to place its nose for the machine to dispense food. It is created with an Arduino Nano, servo, LEDs, transistor, MOSFET, potentiometer, and resistors. Its enclosure was made with recycled household materials, although ...
