PWM Speed Motor Controller By IC 555

This 555 timer based PWM controller features almost 0..100%

This 555 timer based PWM controller features almost 0..100% pulse width regulation using R1,
while keeping the oscillator frequency relatively stable. The frequency is dependent on values of R1 and C1,
values shown will give a frequency range from about 170 to 200 Hz. Any 555 chip will do, CMOS is fine as well.
Diodes are not critical, I used 1N4148. Total cost of parts is about $2. As the whole thing is quite trivial,
it’s very easy to build on prototyping board like I did (as you can see, one of capacitors –
C1 is replaced with different value, 0.047 uF to be precise):

Simple Timer by CA3140 + NE555

This be the circuit sets the time to model is simple,at can fix the time had long ago and have tall good accuracy. By use pillar equipment be IC CA3140 for fix time mouth and NE555 perform sound electric bell origin. By we can fine time value done to a turn VR1 can fine since 10 second arrive at 3 hour. When the time expires will have an electric bell that a loudspeaker. For the equipment that should choose specially. Be C1 100uF 16V values should are a kind Tantalum. Because tall quality more Electrolytic. The moderately but if no enough replace can sir. Request friends have fun the circuit sets the time this please sir.
