Simple Basic Time Delay Circuit Using NPN Transistor. |
In This Video, We Discuss the Making of Simple Delay Timers Using Very Ordinary Components Like A Transistor, Capacitor, And Resistance. This Circuit Will Produce Delay On-Time Intervals at The Output for A Predetermined Period, From A Few Seconds to Many Minutes. According To The Resistance And Capacitor Used.
Things Needed for the Basic Time Delay Circuit:
-Bc547 Transistor NPN. (Or Any NPN Transistor)
-Push Button. (You Can Use Any Push Button You Have)
-9v Powers Supply. (You Can Use A Lithium-ion (Li-ion) Battery 18650,3.7v)
-Red Led. (Any Color Led Just for See Delay Time)
-15kΩ Resistance. (You Can Use 10kΩ Resistance or Big Value for More Time Delay)
-470Ω Resistance. (You Can Use 220Ω This Resistance for Protecting Your Led)
-100uf Capacitor. (You Can Use Big Capacitor Range for More Time Delay)
-9v Battery Holder. (For Connect Your Circuit With 9v Battery)
