 Connect Arduino Uno to your laptop using the USB cable (Type A to Type B). Copy paste the Arduino Sketch given below in Arduino IDE v1.8.19 that you downloaded earlier:
 
-:fab:`github;pst-color-primary` `Spike recorder arduino code <https://raw.githubusercontent.com/BackyardBrains/SpikerShield/master/Muscle/Arduino%20Code/SpikeRecorder/SpikeRecorderSpikerShield_V1_1.ino>`_

 Go to ``tools`` from the menu bar, select ``board`` option then select Arduino UNO. In the same menu, 
 select the COM port on which your development board is connected. To find out the right COM port, screen
 disconnect your board and reopen the menu. The entry that disappears should be the 
 right COM port. Now upload the code.

-Open the Spike Recorder software. When the Spike Recorder starts, it will start recording from your microphone. To change that, go to the settings by clicking 
-the first icon on the top left corner of the screen, select the COM port on which your Arduino UNO is connected and click on connect.

-Mute the speakers and apply the 50Hz notch filter by clicking on the checkbox as shown in the screenshot above. You should 
-set the low band pass filter to 1Hz and high bandpass filter to 40Hz as we are only recording the EEG signals which range between 
-these frequencies.

 The signals that you can see on the screen right now are originating from prefrontal cortex part of your brain and propagating through all the layers to the surface of your skin.
 
-To record these EEG signals, you have placed the electrodes on the forehead (Fp1 & Fp2), then BioAmp EXG Pill is amplifying those signals so that we can detect it and finally sending it to the ADC (Analog to Digital Convertor) of your Arduino Uno. Ultimately the signals are being visualized in Spike Recorder software.

 We hope everything is clear now and you understand how the signals are propagating from your brain to the screen of the laptop.
 
-**Features of Spike Recorder that you can explore:**
-
-- Increase or decrease the scale of the Y axis by clicking on the + and - icons respecitively that is present on the left side of the graph.
-- Increase or decrease the X axis timescale by sliding up and down on the scroll wheel of the mouse.
-- Visualize the FFT graph by clicking on the FFT icon on top left size of the screen.
-- Record the data in .wav format by clicking the record icon on the top right corner. You can convert this data in any other format according to your project requirements.
-- Listen to the signals by clicking the volume icon on the top right corner. No don't smile right now, that's how your brain sounds like :P
