As found in the schematic of the generic PIR motion detector module, one pin of the LDR goes to ground rail (0 V ... on-board voltage regulator, and Arduino IDE compatibility. The code is an Arduino ...

The game is based on an Arduino Nano, to which five LEDs as well ... player has a limited time to “shoot” the corresponding LDR with a laser pointer. This time limit is decreased as the ...

you need to program Arduino to read a sensor and direct the data to the Serial Port. Here, a standard light-dependent resistor (LDR) is used as an analog input sensor and directs its output to the ...
