Txij li thaum kuv luam tawm thiab pib siv rooj plaub no rau kuv Retropie Kuv ib txwm xav tias yuav ua li cas kom khawm lub zog. Lub tswv yim tau hloov pauv tus qauv txhawm rau txav lub pob thiab tom qab ntawd hloov qhov hloov pauv. Thaum kawg kuv muaj lwm lub tswv yim, qhov twg kuv tsis xav tau hloov rooj plaub. Siv 555 raws li monostable Kuv ua qhov kov hloov.

Kauj Ruam 1: Qhov Chaw

  • 1 - LM555 timer
  • 1 - 2N7000 FET
  • 1 - 10k resistor
  • 1 - 100k resistor
  • 1 - 330k resistor
  • 1 - 680k resistor
  • 1 - 10 nF capacitor
  • 1 - 10uF capacitor
  • 1 - Universal PCB

Lub Circuit Court yog qhov yooj yim, thaum tus pin 2 ntawm 555 tau txais cov mem tes ntawm "ntiv tes" 10uF lub capacitor pib koj lub nqi thiab cov zis 555 (tus pin 3) mus rau qib siab thiab tom qab ntawd thaum lub capacitor nres them cov nqi mus rau qib qis. Rau Raspberry Pi tig rau yog xav tau tus pin 5 (GPIO3) mus rau qib qis. Txhawm rau ua qhov no tau siv FET 2N7000 thiab qhov kev tawm tsam tiv thaiv, qhov twg tiv thaiv kev faib khoom faib tawm 3.3V rau tus pin 5 ntawm Raspberry Pi thiab thaum lub rooj vag FET tau txais qib siab, 3.3V teeb liab mus rau qis ua haujlwm raws li hloov pauv.

Rau kov tau siv ib daim ntawv ntawm daim clip raws li duab.
