design an electronic circuit on a bread boar d or a PCB having three push button s, two toggle switches and three high intensity LEDs ( blue, red an d green).
CON DITION ONE:
When mode‐1 is switched on as shown in the figure, and any of the three switches are pushed, the blue, red and green LEDs should glow consecutively for 5 seconds each, in the specified order. This pro cess (blue‐red‐green‐ blue‐ red‐green‐ blue‐ red‐green‐and so on) should stop when mode 1 is switched off. When o ne bulb is on, the other two should be off.
While mode‐1 is running, pressing of an y three switches or on/off of mode‐2 should not affect the mode‐1 process. CON DITION TW O:
When the execution of mode‐1 is completed and it is switched off, mode‐2 is switched on and it has to do the following:
‐ When switch‐1 is pressed, blue and red LEDs should glow. ‐
When switch‐2 is pressed, green and blue LEDs should glow. ‐ When switch‐3 is pressed, red and blue LEDs should glow.
‐ While mode‐2 is running; o n/off of mode‐1 should not affect th e mode‐2 process.
‐ When mode‐1 and mode‐2 are off, pressing of either of the three switches should not affect the LEDs.
** The use of any microcontroller, microprocessor, mux, de mux, gate or IC is prohibited.
**The circuit should contain basic components like transistors, resisters, capacitor s, inductors and diodes **only. Apart from these can use 555 timers and o p‐amps.
