Arduino Serial Communication and plotting the graph against the values.

Step 1: Watch Video

With New Arduino 1.6.5 IDE you can plot any sensor value in a Decent looking Graphs. You can Hook up a DHT-11 Sensor and can Make Temperature and Humidity Graph. You can Hook up an LDR Sensor and Can Generate Different Functions e.g. Square, SawTooth, Triangular, Sine and Cosine

Step 2: Required Components

  • Arduino (any)
  • Arduino IDE 1.6.5 or later installed.
  • LDR Sensor
  • 10K ohm Resistor.
  • if you want to provide temperature graph use lm35

Step 3: Function Generation.

You can Generate all these types of function and observe the graph.

  • Sine and Cosine
  • triangular
  • Saw toothed
  • Square Signal

Step 4: Code:
