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.
- bread board
- Arduino UNO
- 330E Resistor
- Jumper wire
- 9-12 volt power supply
Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.
Step 1: Assemble the Circuit
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.
Step 2: Connect the Buzzer
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
Step 3: Upload the EEPROM Counter Code
Upload the EEPROM code to your board using arduino IDE.
Step 4: Upload the EEPROM Read Code
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.
