The simple oscillator circuit is designed with a common NAND gate IC of CD4011, which can deliver the oscillation frequency of 1.3KHz. This frequency is enough for the siren or warning sound. Are you planning to build a warning sound…
The LED flasher circuit is using in many situations such as alert, decorative lighting, Testing and debugging, and also the signal transmission. The CD4011 IC based LED flasher is designed with minimum number of external components and easy to build…
This simple touch ON/OFF circuit is designed using CD4011 IC. The normal flip-flop flop, process is happening here. The pin number 9 and the pin number 13 is the signal receiving pins. The presence of the touch of your finger…
