As mentioned before, our favorite idea was to have a board game where the user felt that they were not studying or doing something tedious.
Therefore, creating a board game with an original idea was not enough. Reading to verify the answers can take a lot of time to localize the character of Flag you are looking for, therefore we wanted to have something fast and that didn’t necessary required too much space like the “Makey Makey”.
We did extend research and we decided to use a device called ISD1820. This device is a voice recorder module; a multiple-message record/playback device.
In other words this device allows to user to pre record messages and reproduce it when one of the two buttons for reproduce is pressed.
The red button (record message) as it name indicates, it’s for record a message. You have to keep pressed the button while recording your message, once the message is concluded you may unpressed the button. You can record messages up for 20 seconds.
The button that is next to the red button is called (Playe), this black button reproduces the message that you recorded with the (record message), once you touch this (Playe) button it reproduces the entire audio.
Finally, the last button (Playl) is another button to reproduce the message, however; you need to lee this button pressed to listen the audio, if you don’t hold it until the end, the message/audio is interrupted.
Next step was to give power supply to the ISD1820. This device has 2 male entrances in order to generate power and make it work. The first one is called “VCC”, as expected it is the entrance for voltage supply (+, red cable), next to this entrance is located the “GND”, this is the entrance for ground (-, black cable)
The ISD1820 is able to resist a voltage of 5V. Therefore, as a suggestion we recommend using 3 AA batteries that add 4.5 V (1.5V each). We use a case to storage the 3 batteries together and pull out the power supply together.
However the voltage and ground cable that came from the case had male entrances as well. As a result we had to rearrange and installed a female entrance to each cable. We did this through cutting random cable with a female entrance and then soldering the other extreme of the the cable that didn’t have the female entrance to the cable that was attach to the power supply. We repeated this procedure for the other cable left. We added some black tape to both of the soldering part to reduce any loose.
Finally, we connected the red cable from the power supply to The VCC entrance and the black cable from the power supply to the GND entrance of the ISD1820.
In order to test the ISD1820, we recorded a message that said the following: “Zinadine Zidane, France, Europe”, the message was successfully played and we were able to listen to it, however the audio volume was quite low, therefore, this was something to consider for the final version.
