Hi, I asked my electronics teacher for some help but he isn’t bothered so that is why I need help from you guys.
I am constructing a loop wire game in which you have to move a loop through a wire and once the loop touches, it warns you etc by buzzing and/or the use of LED/s. Here are the two schematics that I would like to combine. Also I have attached an attachment if the link isn’t working.
The problem in the FIRST SCHEMATIC is that the buzzer will not sound for a predetermined time. The buzzer will only sound as soon as the loop touches the wire and won’t sound after the loop doesn’t touch the wire. The problem in the SECOND SCHEMATIC is that it doesn’t involve LED/s to stay lit and a reset button like the FIRST SCHEMATIC.
I would like the combined schematic to function like this: When the loop touches the wire (acting as a switch shown in the schematic), the buzzer will sound for a predetermined time varying on the capacitor value and the LED will stay lit, and when the push to make switch(reset) is pressed, the LED will turn off.
If someone can give me some guidance on how I should approach this problem, or if someone can provide me with the Solved Schematic of the above two schematics, then I’ll be really grateful.
Later on, I will use Arduino Uno to add countdown timer. Any suggestions would be appreciated.
Thanks A Lot
