In order to drive high power outputs with arduino such as high power dc motor high power led we need a mosfet to do the job so lets get started.
Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.
Step 1: Gather Your Components
BUY PARTS :
BUY ARDUINO UNO:
BUY 12V ADAPTER: https://www.utsource.net/itm/p/8013134.html
so to drive high power outputs we need some components as gien below
Arduino uno- https://www.banggood.com/Wholesale-Arduino-Compat...
12v power Supply
Dc motor / high power led as output
Step 2: Connections
follow the connections shown in schmatics otherwise refer to the video.
TThThe logic is really simple the voltage provided by Arduino on the gate of Mosfet will decide its output current, so higher the voltage higher the current. Ko
Step 3: Compatibility
You can use any of the Mosfet's but when it comes to choose one of them try to use IRLZ44N because it is a logic level MOSFET so it will respond for low voltages too that means current will conduct even on 2.5v or 3..3v or 5v but in IRFZ44N & IRF530N they will provide enough current for the operation at such voltages and driving high current such as 8 or 10A by gate voltage 5v they heat too much so avoid them but if you want to use IRF530N or IRFZ44N then go for IRF530N
Step 4: All Done
So finally i hope you learned a little bit from this instructables and you know how to use MOSFET with arduino.Refer video to avoid any sort of confusion and demonstration of Mosfet with arduino and connections.
