Feedback Collection System

It is always interesting to collect feedback post-events and workshops. To solve that problem, we have made an arduino-based feedback collecting system.

In this project we'll make a electronics device which will gather feedback as per button pressed, using Arduino UNO and switches.

Apparatus:

• Switch
• bread board
• Arduino UNO
• 330E Resistor
• Jumper wire
• Buzzer
• 9-12 volt power supply

Connect 3 switch in voltage divider rule with 330E resistor and connect the output to Arduino's analog pin.

Here I used the Arduino UNO's analog pin A0, A1, A2.

Buzzer is used here as audio output of confirmation of recording of vote.

Connect the buzzer to output digital pin 12 of Arduino.

I use this buzzer to check whether the vote process has been done succesfully or not of individual person .

If the vote has been done succesfully ,then the buzzer will be sound on after pressing any button

Upload the EEPROM code to your board using arduino IDE.

Once the feedback collection has ended. Upload the EEPROM read code to get the value of votes recorded.

For testing purpose : You can press any switch and see how many time you press it in serial monitor. The serial monitor will show you the EEPROM value.
