Project: Smart Aquarium light
An aquarium light controllable with your smart phone.
What is it?
The smart aquarium light is the lighting I use for my aquariums. It can be controlled with an app on my phone using Blynk. You can set what values the 5 color (Red, Green, Blue, warm white, cold white) LED's are on at certain times. You can make it have a smooth transition between those times when it switches, and also at what time it does it. You also get a readout of the current aquarium water temperature.
How is it made?
The light is controlled using an esp8266 module, this is a microcontroller with WiFi capabilities. The controller uses PWM to control the 5 light channels on a 12v led strip, it does this via MOSFETs. There is also a onewire waterproof temperature sensor connected to the controller to be able to read out the temperature of the water. The outside is made from laser cut plywood and has a small led screen to show the time and water temperature.
