Arduino nRF24L01+ and MOSFET Wiring
0:57
I've inserted the following components into your schematic:
-
The nRF24L01+ module (designator U2) connected as follows:
- VCC to the Arduino U1 3V3 pin
- GND to the Arduino GND
- CE to Arduino digital pin 9
- CSN to Arduino digital pin 10
- SCK to Arduino digital pin 13
- MOSI to Arduino digital pin 11
- MISO to Arduino digital pin 12
- IRQ left unconnected
-
The MOSFET circuit has been added by inserting:
- The IRLZ44N MOSFET (designator Q1)
- A 470Ω resistor (designator R1) between Arduino digital pin 6 and the MOSFET Gate
- A 10kΩ resistor (designator R2) from the MOSFET Gate to GND (to serve as a pull-down)
The wiring for the MOSFET is as follows:
Table
| Connection Point | Connection | Description |
|---|---|---|
| MOSFET Gate (Q1) | Connected via R1 (470Ω) to Arduino digital pin 6 and via R2 (10kΩ) to GND | Receives PWM control with pull-down protection |
| MOSFET Drain (Q1) | Connected to the negative terminal of the LED (designator LED1) | Switches the LED circuit |
| MOSFET Source (Q1) | Connected to GND | Common ground |
| LED Positive (LED1) | Connected to the 12V power supply | Supplies 12V to the LED |
All wiring connections have been set according to your provided instructions.
