You are watching simple DIY video about How to Use Transistor as Relay.
"The Purpose of this circuit is to save the time(micro or milli seconds) which relay is wasting in doing mechanical work. As we know that some circuit require fast switching On/off system e.g Arduino projects so transistor is the best alternate in that type of circuits because transistor works very much faster as compare relay which is dependent on mechanical switching principle by using current."
Hi viewers! in this video i am going to show you how to use any NPN Transistor as DC Relay or Switch by using cheap NPN Transistor and 1K or 10K resistor depending on input voltage.
List Of Materials
1. NPN Transistor(I'm using 2N2222A): https://s.click.aliexpress.com/e/_dXNbjC9
2. 1k or 10k resistor depending on input voltage: https://s.click.aliexpress.com/e/_d7SJjB7
and some basic tools are
Soldering Iron: https://s.click.aliexpress.com/e/_dT1NOzX
Soldering Paste: https://s.click.aliexpress.com/e/_dZq0mhB
Hot Glue Gun: https://s.click.aliexpress.com/e/_dYsNoCd
Third Hand Tool: https://s.click.aliexpress.com/e/_dZZlFXB
Multimeter: https://s.click.aliexpress.com/e/_dZuPdCh
Drill & Electric Screwdriver: https://s.click.aliexpress.com/e/_d8uUE3F
Cordless Drill: https://s.click.aliexpress.com/e/_dTl3rFf
