A 12-LED NeoPixel ring provides lighting and a TM1637 4-digit 7-segment display reads out the ambient temperature, while an MCP9808 temperature sensor is used to measure the ambient temperature (you could use a different sensor, such as the Dallas DS18B20). The lamp is internally fused for safety. A momentary push button has been added to provide additional functionality such as different modes (eg moodlight), brightness levels and on/off. I have included a basic sketch that I cobbled together out of some example code (demonstrated in the video), but I'm afraid I just don't have the time right now to write a fully featured sketch... <br> <br> <b>WARNING: This lamp is a novelty item. No claims are made about the accuracy and/or safety of this device. Make and/or use at your own risk.</b> <br> <br> <em>About the Temperature Sensor...</em> <br> A temperature sensor in a through-hole package such as the Dallas DS18B20 might give more accurate readings, because you can stick the sensor out of the base into the thruster (that's what I made the hole for). I found that the MCP9808 reads about 4 degrees high at 21 degrees due to internal case heating, so this needs to be compensated for in software. <br> <br> <em>Required Hardware (Links are examples- use your preferred supplier)</em> <br> 1 x <a rel="nofollow" href="https://www.banggood.com/ATmega328P-Nano-V3-Controller-Board-Compatible-Arduino-p-940937.html?rmmds=search&cur_warehouse=CN">Arduino Nano v3</a> <br> 1 x <a rel="nofollow" href="https://www.banggood.com/Mini-DC-DC-Converter-Step-Down-Module-Adjustable-Power-Supply-p-920327.html?rmmds=search&cur_warehouse=UK">Buck Converter</a> <br> 1 x <a rel="nofollow" href="https://www.banggood.com/CJMCU-12-Bit-WS2812-5050-RGB-LED-Driver-Development-Board-p-984259.html?cur_warehouse=CN">12-bit WS2812 LED Ring</a> <br> 1 x <a rel="nofollow" href="https://www.banggood.com/0_36-Inch-LED-Digital-Tube-Display-Module-TM1637-Common-Anode-Light-Adjustable-p-1097873.html?cur_warehouse=CN">TM1637 4 Digit 7 Segment Display</a> <br> 1 x <a rel="nofollow" href="https://www.adafruit.com/product/1782">MCP9808 Temperature Sensor</a> <br> 1 x <a rel="nofollow" href="https://www.amazon.com/DIYhz-20Pcs-Momentary-Button-Switch/dp/B075LLP2LH">SPST NO Momentary Button</a> <br> 1 x <a rel="nofollow" href="https://www.banggood.com/10pcs-DC-022-5_5-2_1mm-Round-Hole-Screw-Nut-DC-Power-Socket-ROHS-Internal-Diameter-5_5mm-p-1200831.html?rmmds=search&cur_warehouse=CN">DC Power Socket</a> <br> 1 x <a rel="nofollow" href="https://www.amazon.co.uk/Fuse-Holder-5x20-Glass-25pofus001/dp/B074FSXM47">5x20mm Inline Fuse Holder</a> <br> 1 x 5x20mm 500mA Glass Fuse <br> 1 x 470Ω resistor <br> Heatshrink <br> Kapton tape (or other insulating tape) <br> Hot-melt Glue <br> Superglue <br> <br> <em>Build Guidance</em> <br> <ul> <li>All 3D printed parts require supports.
