Now that you know what is the best LED strip for your project, you can go to Maker Advisor to find your strip’s best price. LED density: this means how much LEDs the strip has per meter. You can find a wide variety of LED densities since 30, 60, 72 , 120 LEDs per meter and other options. MOSFET spec sheets can look pretty complicated, but for many applications we just need to pay attention to a few key parameters that are explained here.

The non waterproof strips are lighter, so it is easier if you want to hang them on the bottom of something with tape. The image below shows an example of a non waterproof LED strip. Alternatively I have a couple of 2N3904 transistors available but I am not entirely sure how I can use these without frying them. Then, you can control the strip with PWM as you would do to control a single RGB LED. To find out how to control an RGB LED with the Arduino you can read: How do RGB LEDs work? According to the datasheet Vds max = 30V, what is much higher than 11.1V, so you are good in this regard.

V GS : Gate Voltage is the voltage differential between the Gate and the Source which is how hard the MOSFET is being driven.

Monocolor LED strips only produce one color. These strips are really easy to wire, they just have two terminals: GND and VCC as shown in the strip below. Waterproof or not. The LED strips can be waterproof or not. The waterproof LED strips are coated in a clear silicon as the strip shown below. frequencies you need to ensure shorter RC time constant in the gate-drive circuit. This usually meansThe very low ‘ON’ resistance means that there is very little voltage drop through the device and that also helps to keep power dissipation down. Capacitance isn't quite the right thing as gate charge is non-linear, and more thorough calculations I have looked this up extensively and tried it on my breadboards but with no success. Only lead I have is pointing to a fairchild mosfet which I am not able to get to for weeks. V GS(th) : Gate Threshold Voltage is the voltage at which the MOSFET starts to conduct. Any voltage less than this will drive the MOSFET to the OFF state known as the Cut-Off Region. To possibly be logic compatible, the V GS(th) needs to be well under the logic high voltage level.

You get a temperature rise related to power (Watts) so yo might need a heatsink on a hot day even if you don't need on a cold day. Power is calculated as Voltage x Current. By calculating the RC time constant and thus the rise/fall time of gate voltage - during rise and fall the The other two are hard to predict... Sometimes the datasheets will give you the maximum power dissipation without a heatsink, and sometimes they they'll give you information about the maximum internal die temperature, power dissipation, and thermal resistance. Calculating the thermal resistance and temperature drops can get "messy".Edit for clarification: I'm using the 5V pin to power the board via the 12V power source (through a 5V regulator). I've tested the software using an LED and the signal is deifnitely coming through fine. Also, this is just a uni prototype, so as far as I'm concerned if a solution works short term but wouldn't be viable in a final product I can just add that to the report! You need a driver circuit to boost the power – add a transistor amplifier in each control line. For example, you can use N-channel MOSFETs like the IRLB8721 that work with 3.3V and 5V logic. So, they are suitable to use with your Arduino or ESP8266. In this post we’ve shown you the main differences between the various types of LED strips out there.
