Arduino MOSFET circuit design
Budget: $10 – $15 USD
For this project, I would like to turn on and off an LED and a 5V LiDAR using a 3.3V Arduino Pro Mini and two MOSFETs.
I have:
1x 3.6V 18650 battery
1x 3.3V Arduino Pro mini - https://cdn.sparkfun.com/datasheets/Dev/Arduino/Boards/ProMini8MHzv1.pdf
1x LiDAR - https://cdn.sparkfun.com/assets/1/4/2/1/9/TFmini_Plus_A02_Product_Manual_EN.pdf
1x 5V boost converter - https://www.pololu.com/product/2564
2x BS170/MT3608/IRF540/IRL520N/IRFZ44 MOSFETs
1x LED + 560ohm resistor
I would like a circuit design that is able to turn the LED on and off using a MOSFET and turn the boost converter (with 5V LiDAR) on and off using a MOSFET. The MOSFETs are controlled by pins 1 and 2 of the Arduino.
Currently using the sketch included with the project, a BD170 and an LED, the current from the 3.6V battery is 4.3 uA while the LED is off and 3.05mA while the LED is on.
Successful completion of this project includes a circuit design and an ino sketch that will be built and tested by myself using the components listed above, being able to turn on and off the LED as well as the LiDAR independently and having a battery current of less than 10uA while both MOSFETs are set to LOW on the Arduino. The LiDAR should also output correct distance values using the TFMPlus library by Bud Ryerson.
