Ib qho yooj yim Synthesizer siv Schmitt txhais
Rau lub voj voog no, koj yuav xav tau txuas lub suab tso rau lub guitar amp. Lub tso suab tsis tu ncua yuav tsis muaj txiaj ntsig txaus los hnov lub teeb liab.
Schmitt txhais yog ib hom kev pib nrog cov lus pom zoo. Lub Circuit Court yog lub npe "txhais" vim tias cov zis khaws nws cov txiaj ntsig kom txog thaum cov tswv yim hloov pauv txaus kom ua rau muaj kev hloov pauv. Schmitt txhais yog cov khoom noj khoom haus multivibrator; hauv nws qhov kev hloov pauv nws tuaj yeem siv ua oscillator. Kev siv hluav taws xob sib txuas ua ke peb tab tom siv yog hu ua hex Schmitt txhais vim tias nws muaj rau inverters rau ntawm ib lub nti. Txog qhov kev tawm dag zog no, koj tuaj yeem siv 74C14 lossis CD40106, lawv yog ob qho Hex Schmitt Triggers.
Tib inverter
- tus pin 14 mus rau qhov hluav taws xob
- tus pin 7 mus rau hauv av
- R1 = 10k (resistor ntawm tus pin 1 thiab tus pin 2)
- C1 =.1uF (capacitor ntawm tus pin 1 thiab hauv av)
- Cov lus qhia kub ntawm lub suab txuas txuas rau tus pin 2, uas yog OUTput teeb liab
- Lub tes tsho ntawm lub suab txuas txuas rau hauv av
Kauj Ruam 1: Teeb Ib Tus Oscillator, thiab Txuas Nws Kom Peb Thiaj Li Tau Hnov Nws
Kauj Ruam 2: Hloov Tus Tiv Thaiv Nrog Photoresistor
Kauj Ruam 3: Hloov Tus Kws Tshaj Lij nrog Potentiometer
Kauj Ruam 4: Multimeter: Ntsuas qhov Kev Tiv Thaiv ntawm Photoresistor thiab Potentiometer
Sau qhov ntau ntawm qhov tsis kam rau koj lub hwj chim thiab photoresistor.
Ob lub inverters
- tus pin 14 mus rau qhov hluav taws xob
- tus pin 7 mus rau hauv av
- R1 = 10k (resistor ntawm tus pin 1 thiab tus pin 2)
- R2 = 10k (resistor ntawm tus pin 3 thiab tus pin 4)
- C1 =.1uF (capacitor ntawm tus pin 1 thiab hauv av)
- C2 =.1uF (capacitor ntawm tus pin 3 thiab hauv av)
- R3 = 10k (resistor ntawm tus pin 2 thiab tawm)
- R4 = 10k (resistor ntawm tus pin 4 thiab tawm)
- Qhov kub taub hau ntawm lub suab txuas txuas rau OUT
- Lub tes tsho ntawm lub suab txuas txuas rau hauv av
Kauj Ruam 5: Siv Ob Tus Inverters
Txhawm rau txuas ntau tus inverters rau tib lub suab tso tawm, xa txhua lub teeb liab los ntawm 10k resistor uas txhua qhov xaus ntawm qhov kub tshaj ntawm lub suab nkaus. Ua si nrog lub teeb liab, tuaj yeem hloov R1 thiab/lossis R2 rau qhov sib txawv resistors zoo li potentiometer lossis photoresistor.
Kauj Ruam 6: Siv Peb Inverters
Kauj Ruam 7: Siv Peb Inverters
Lub sijhawm no siv 10k resistor rau inverter #1, potentiometer rau inverter #2, thiab photoresistor rau inverter #3.
