Hey Folks,
I recently bought a Adafruit Trinket M0 for a cosplay prop I'm working on.
I used this video as reference: Animated LED Basics - YouTube
The idea was to create a "heartbeat effect" for an amulet. I'm a complete beginner in electronics, so I've done some research and asked a friend who has some basic electronic understanding.
I've gotten the code like I've wanted, now the only issue seems to be that there isn't enough power, or the correct wiring is unclear to me.
I have two questions:
-
Do I need a powerboost to use a single 3V LED? Is this component necessary or will a coin battery work?
-
If I don't need a powerboost, what is the proper diagram/setup? To me, it looks like the LED is sapping the Trinket's power.
My current components are:
- 3V Coin Battery
- Switch
- Adafruit M0 Trinket
- 3V Red LED
Here are some images and my mock diagram that I used. The reason I'm not using a boost or a 6/9V battery is because I want to keep this as light weight as possible. However, if it is a must, then I'm fine with that I just wan't to make sure I'm not missing something obvious.
Here is a screenshot of the cosplayer's setup. It's using a PowerBoost and a Battery pack.
Here is a crude diagram I used to set my LED up. I notice that it will bypass the trinket if the red wire coming from the LED touches the 3V or Rst on the Trinket. The trinket turns on normally if the LED is not hooked up. My assumption is that there isn't enough power.
Here's a picture of the wired setup. It also appears that the battery is drained super fast. That's why it looks like its off.
P.S. the image insert doesn't appear to work, or Imgur isn't supported. Any suggestions on that?
