Learn to hook up a lightweight sensor to regulate the brightness of an LED based mostly on ambient gentle. Now that is a fast circuit creation!
Construct a Visible Ambient Mild Sensor
Typically, you do not want a knowledge stream in your laptop display to let you know what is going on on. Typically it is extra enjoyable to let your circuit do the speaking!
That is the concept behind this little Qwiic Circuit Creation utilizing the SparkFun Ambient Mild Sensor, a RedBoard Qwiic, and a Qwiic Button. Hook them up with a few Qwiic cables, add the instance code, and you’ve got a visible indicator that responds to modifications in gentle.
When the room is darkish, the button glows vibrant. Shine some gentle on the sensor, and the button fades. It’s that straightforward, and that’s what makes it so helpful.
See It in Motion
We made a rapid Brief to point out simply how simple that is:
If you want a better take a look at the sensor itself and what it might probably do, try the complete video right here:
Why Trouble with a Visible Mild Indicator?
Positive, you may open up a serial monitor and watch the lux values scroll by. However typically it’s good to see your sensor knowledge proper in entrance of you. A glowing button that reacts in actual time is:
- Nice for demos: immediate suggestions while not having a laptop computer.
- Good for lecture rooms: makes sensor knowledge approachable and tangible.
- Useful for initiatives: lets the circuit let you know when it’s too darkish or too vibrant.
- Expandable: you should utilize the identical enter to set off actions like turning on a lamp, adjusting a display, and even closing blinds.
The best way to Construct It
We put collectively a step-by-step tutorial that walks you thru the wiring, code, and logic:
All you have to is:
SparkFun RedBoard Qwiic
DEV-15123
Qwiic Cable – 100mm
PRT-14427
That is it! No soldering. No breadboards. No headache.
Wrapping Up
This venture is a straightforward instance of how highly effective the Qwiic ecosystem will be. With just some components, you may go from thought to working circuit in minutes.
