In this experiment, by programming the Raspberry Pi, we detects whether a flame has 
been encountered. 

Experimental Procedures  

Step 1: Build the circuit 

 

For C language users: 

Step 2: Edit and save the code with vim or nano. 

(code path: /home/Adeept_Sensor_Kit_for_RPi_C_Code/17_flame/flame.c) 

Step 3: Compile 

$ sudo gcc flame.c -o flame -lwiringPi

 

Step 4: Run 

$ sudo ./flame
