| + | Arduino reads the voltage drop across the LDR. Observe the voltage for black and white tiles, and choose a suitable threshold voltage to say Vt ( in this case it's 700). If the voltage is less than the threshold voltage, then there is a larger drop across LDR, the larger the resistance, which implies a Black tile and vice versa. I have simulated the touch accordingly. The values of the delays can be tweaked to get the best result. | ||

| + | * Pin 4, 5, 6, 7 -> Relay output | ||
| + | * Pin A2, A3, A4, A5 -> Analog input value from the LDRs. | ||
| + | * Analog value less than 700 implies it Black tile. | ||
| + | * NOTE: It is to be calibrated based on ambient intensity and screen brightness. | ||
| + | * Used void loop() and void setup(). | ||

| ===== Conclusion ===== | ===== Conclusion ===== | ||
| + | |||
| + | I have managed to complete all the requirements for a good project. There are still small problems regarding the LDR because of the phone's screen and the Relay's ability to conduct. I have learned how to use Arduino software to connect LDRs wires and coins accordingly so that the current will go through the coins correctly. | ||
