8)SMD LED matrix
7)1 sec delay using 555 timer
6) Soil moisture sensor module with rectifying circuit
5)Matrix LED interfaced with Arduino
Single layer is not possible with this circuit
Modified circuit :
The resistors connected inside the matrix will be replaced by 0 ohm resisters/wires. Hence,our design could be implemented in single layer itself
4)Matrix LED using NE555
Proteus simulation :
2) DC Motor using PWM -To operate in both directions using separate switches
Proteus simulation :
3)PWM
1) Full wave rectifier
