Block Diagram Description
Reed Switch
Reed Switch
v
Electrical
switch operated by an applied magnetic field. Reed switch used as
sensor in this circuit. When the magnet join together it will trigger the IC
4098 dual monostable retriggerable.
CD4098BMS
v Dual monostable
multivibrator provides stable retriggerable/resettable one shot operation for
any fixed voltage timing application. This IC will made short retriggerable
operation before continue to IC 4093 Schmitt trigger.
CD4093BMS
v
Consists of
four Schmitt trigger circuits. Each circuit functions as a two input NAND gate
with Schmitt trigger action on both inputs. The gate switches at different
points for positive and negative going signals. This IC will made inverse
operation to turn the negative positive signal.
Piezo Sounder
v
Buzzer is
audio signal device that produce sound. The piezo sounder will produce
irritating sound when get an input from IC 4093.
L.E.D
v
Semiconductor light
source that produce light and used as indicator lamp. The LED will produce
light when get an input from IC 4093.
Good and clear description of overall project overview. The objectives can be further improve.
ReplyDeleteNext I want, in each entry for you to include:
1. The week Activity
2. Its result
3. Plan for next week.
Example:
Week 9: Build up Schmitt trigger circuits. (Include also the cct diagram.)
Result: In progress. Problem with installation process. Hard to solder the component into complete UV board.( include the photo of your work)
Plan for Week 10: continue on construction of Schmitt trigger circuits.
