Led flickery flame soldering kit5/29/2023 ![]() ![]() The power and color of the LEDs is controlled using Pulse Width Modulation (PWM) on a range of 0-255. The brightest setting of these LEDs is extremely bright and difficult to look at, which is great because more brightness draws more power. Fortunately, there is a mixture of colors for this example which lessens power consumption a lot, sometimes by half. With one RGB LED, we have around 65mA to supply in the worst case of displaying white at the brightest setting, depending on your battery this might not last long at all. The current draw of the RGB LEDs depends on colors and brightness: No matter what, it is good to know roughly how long a project will last before you need to recharge, change batteries, or unplug it to conserve power. You can make your project last longer by using a bigger battery, turning down the brightness of your LEDs, or adding in some power control like a switch so that you're only using power when you choose. Lower chance = more flickery fire.ĭepending on what effect you are trying to achieve, you may end up changing both of these values. SPARKING: What chance (out of 255) is there that a new spark will be lit? COOLING: How much does the air cool as it rises? There are two lines in the fire effect program you can adjust the values of to create a desired speed/flame effect: ![]() ![]() You can see all of the Predefined RGB colors in the header file pixeltypes.h starting at line 594: If you want to go more in depth, you can change the individual colors using a color palette function referenced in the library. I chose to use the typical colors for a candle flame included in the fire effect example, but there are other effects available in the program. If you want your LEDs brighter you would edit the line: This was done to save power in my case, as will be discussed later on. The default brightness for the attached program is set to 128 out of a scale of 255, so the LEDs are set to 50% brightness. Make the correct tools selections to program the board:Īnd click the Upload button to upload the program. Connect your TinyLily processor to your computer using the TinyLily microUSB adapter, and a microUSB cable. Here's my copy of the code I used:ĭownload the program zip file, and open it in the Arduino IDE. There is a fire effect example that comes with the library, and all you need to do to get it working is changing the pin, and the amount of LEDs. But I already did that so you can download a ready-to-work copy in a zip file here:Īfter you unzip the library, move it to your Documents/Arduino/libraries folder so that your Arduino sketch program can use it. To make the library usable for Arduino, you have to rename it, as noted in the README on the GitHub page of the library. The fantastic FastLED library makes programming RGB LEDs easy! You can use any pin, but make sure that if you use a different pin that you change the program to reference that pin! I used pin 3 for this project, as can be seen in the above image. The circuit is a simple three connections from the TinyLily Processor to the TinyLily RGB LED.Ĭonnect either one of the power ( +) and ground ( -) tabs to the power and ground on the TinyLily RGB LED, and then you can choose any of the GPIO pins available on the TinyLily to connect to the IN tab of the LED. You can use a Jack-O-Lantern, or any spooky decorations you have, you can even 3D print a Ghost on Thingiverse.Basic Soldering Equipment (Soldering Iron, insulated wire, solder wire) - this is if you prefer soldering to sewing with conductive thread!.TinyLily Starter Kit - Includes everything above and more!.TinyLily Basic Kit - Doesn't include everything above, but it's a great place to start.Kits are the best way to get all of these items:.Tiny Battery Charger - to recharge batteries.TinyLily Battery Adapter - to use project wirelessly.(1) TinyLily RGB LED- to simulatea flame.TinyLilyand TinyLily USB Adapter- the brain of the project.Micro USB Cable- to program my TinyLily Processor.If this is your first time using TinyLily electronics, be sure to check out the TinyLily Processor and TinyLily RGB LED tutorials for some background! It is time to get spooky for Halloween, Samhain, and Día de muertos! This LED Fire Effect can help make your decorations last longer and be less fire-reliant! ![]()
