|- style="border:1pt solid #000000;padding:0.176cm;"
|| '''Show Circuit Diagram.png'''

|| This is the circuit diagram of the '''Temperature indicator '''experiment.

Here, when the temperature value is greater than the defined value the LED is turned ON.

Otherwise the LED is turned OFF.

Let us build this circuit using''' ElectroBlocks'''.
|- style="border:1pt solid #000000;padding:0.176cm;"
|| '''Keep the loop block in the middle area (compulsory)'''

Click on the Logic section

Point to if-then-else block
|| Click on the '''Logic''' section.

Drag the '''if then else''' block and place it inside the '''loop''' block.
|- style="border:1pt solid #000000;padding:0.176cm;"
|| Only narration.
Click on the '''Logic''' option available on the left hand side of the screen.
|| Click on the '''Logic''' section.

The third block represents the '''Comparison block.'''

Select and place this block in the '''if''' section of the '''if then else''' block.
|- style="border:1pt solid #000000;padding:0.176cm;"
|| Narration

Click on the '''Sensors''' section
|| Now we will add a thermistor''' '''block.

Click on the '''Sensors''' section and Click on the '''Thermistor'''.

Select the '''Thermistor Setup '''block and drag it in the working area.

By default, this button will be connected to '''analog pin A0''' of Arduino.
|- style="border:1pt solid #000000;padding:0.176cm;"
|| '''Point to '''Temp in C 23 value.

Click on the number box and change the value to 25.
|| We can change the temperature value to 25 by clicking on the '''temperature in °C '''box.

Note that, in the simulation window, the temperature changes to 25 '''°'''C as well.
Check the '''Copy All''' checkbox.

This setting will set the temperature of the thermistor to 25 degrees for all the 3 loops.
|- style="border:1pt solid #000000;padding:0.176cm;"
|| Only narration

Click on the '''Thermistor''' option.

Place this block in the 1st section of the comparison block.
|| Let's add a thermistor block to read the temperature.

Click on the '''Thermistor'''.

Select the '''Read temperature block''' and drag it in the working area.

Now place this block in the first section of the Comparison block.

Let us set the condition for the temperature reading for the thermistor.
|- style="border:1pt solid #000000;padding:0.176cm;"
|| Click on the dropdown option in the comparison block

select the condition to''' greater than equal to'''
|| Click on the dropdown option in the comparison block.

Select the condition to''' greater than equal to '''as shown'''.'''
|- style="border:1pt solid #000000;padding:0.176cm;"
|| Click on the '''Math''' option

Select the '''number''' block.
|| Click on the '''Math '''section'''.'''

'''Select''' the '''number''' block and place this block in the 2nd section of the Comparison block.

Click on the number block and change the number to 20.
|- style="border:1pt solid #000000;padding:0.176cm;"
|| Click on the LED option.

Select and drag the Turn on LED.
|| Click on the '''Add-ons''' section and click on '''LED'''.

Select the '''Turn a LED ON''' block and place this block in the '''then '''section of the '''If then else '''block.

The LED is connected to '''pin 2''' of the Arduino.
|- style="border:1pt solid #000000;padding:0.176cm;"
|| Click on Time section

Select the wait for 0.2 second block

Drag it in the working area.

Place this block below '''Turn a LED ON'''

Change the time to 1 second

Point to if then block
|| Click on the '''Time''' section.

Select the '''wait for 0.2 second''' block and place this block below the '''Turn a LED ON''' block.

Change the time in the '''wait block''' to 2 seconds.

We have set the blocks for '''LED''' to turn ON for 2 seconds if the temperature value is above 20 '''°C'''

<div style="color:#ff0000;"></div>
|- style="border:1pt solid #000000;padding:0.176cm;"
|| Only narration.

Right click on the '''Turn on LED''' block and select the '''Duplicate''' option.

Drag and place this new block inside the '''else''' section of '''If then else''' block.

Click on the dropdown arrow and select '''OFF'''
|| Right click on the '''Turn a LED on '''block and select the '''Duplicate''' option.

Drag and place this block inside the '''else''' section of '''If then else''' block.

To change the state of the LED, click on the dropdown arrow and select '''OFF'''.

Now we have completed the block setup for this experiment.
|- style="border:1pt solid #000000;padding:0.176cm;"
|| Click on the '''Code''' icon to view the auto-generated Arduino code for the experiment.

Highlight the code on right side
|| Click on the '''Code icon''' to view the automatically generated''' Arduino code'''.

The code includes self-explanatory''' comments''' for better understanding.
|- style="border:1pt solid #000000;padding:0.176cm;"
||
|| Let’s check the working of the temperature indicator using the simulator.
|- style="border:1pt solid #000000;padding:0.176cm;"
|| Click on '''Home''' page and click on the '''Play''' button
|| Click on the '''Home''' icon and press the '''Play button''' to start the simulation.
|- style="border:1pt solid #000000;padding:0.176cm;"
|| Point to simulation window

In the thermistor setup block, change the temperature value to 15 <sup>o</sup>C.

play the simulation button to see the output.

|| We can see the LED turns ON for 2 seconds.

This is because the thermistor temperature is 25°C which is greater than the comparison block .

We will create a situation, where the thermistor reading is below 20<sup>o</sup>C.

In the thermistor setup block, change the temperature value to 15 <sup>o</sup>C.

Now, play the simulation again to see the output.

Notice, the LED remains OFF.
