The connection is obviously as for any other LEDs and the system is capable of driving even power LEDs or LED strip, through appropriate transistor or MOSFET (See: Driving a LED Strip with Arduino) The Arduino code is the following: 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 ...

analogWrite(led,pwm_led); delay(1000); } First of all we have configured the A4 pin of the arduino uno as input pin to read the the LDR sensor output. In the setup function, the “Serial.begin(9600)” command will help in communication between the Arduino and serial monitor. In the ...

I see that your Arduino code reads an LDR (Light Dependent Resistor) sensor and sends a byte over the serial connection when a transition from high to low is detected. The code also toggles an LED based on the LDR reading. You can set up MATLAB to read the data being sent from your ...
This is very similar to the RaspberryPi LDR sensor tutorial, but our circuit & code is a lot easier. This is because the Arduino has analog pins making it super easy to read the value from something such as an analog sensor. You Might Also Like ...
