![]() ![]() I placed the photoresistor in its opening, and then it was time connect the voltmeter. I glued the LEDs in place and then I soldered everything together according to the scematic diagram. I glued it place and it was time to prepare the electronics. It was the first time I was using the dremel tool so the result is far for perfect but it will work just fine. Then I cut asmall piece of Plexiglas using my dremel tool. Now it’s time to post process the parts to make them look even better. As you can see, the enclosure is quite big, that’s why it took 10 hours to print. It took around 10 hours but the result is great! I really love it. This filament looks feels and smells like real wood! It has a fantastic feel, it does not look plastic like PLA that’s why I prefer to use it my projects. I have uploaded the enclosure files on Thingiverse so you can download them from this website for free.Īs I said before, I 3D printed the enclosure using Form Futura’s EasyWood Birch filament. The enclosure consists of three parts that they have to be glued together afterwards. There are a lot of tutorials online on how to use this softwareĭespite the fact that this enclosure is the most complicated object I have ever designed, it took me only 2 hours in Fusion 360! This software is really fantastic!.I tried a lot of different 3d design software but Fusion 360 became my favorite for the following reasons. Now that the circuit is ready, we can move on to the enclosure. You can find the schematic diagram attached on this tutorial. Of course you can change the code and make it work the way you like. Any time the sensor detects that there is light in the room, it will turn the LEDs off. If it detects darkness, it will turn the LEDs on and it will keep them on for 1 minute, if it is still dark. The temperature is displayed on the voltmeter. The Arduino reads the temperature from the sensor, and the light intensity from the photoresistor every second. Now, if we convert the temperature we read from the sensor into voltage we can display it on the Voltmeter! We only need to print a new face for the display, and we have converted the Voltmeter into a thermometer! Let’s begin!įirst we have to build the circuit on a breadboard and make sure it works as expected. ![]() In other words, we can control the needle of the voltmeter at will. The idea is that by using a PWM pin of the Arduino we can output an analog value from 0 to 5V and then display this value on the Voltmeter. You will understand exactly how this project works. I encourage you to read this tutorial by clicking here. So the total cost of the project is around 26$!Ī few weeks ago I published an tutorial where I used an analog voltmeter like this one, and I converted it into a thermometer. So the cost of the enclosure is around 16$ if you print it at home. ![]() I used wood filament in this project which costs 35$ per 500gr roll. The enclosure needs 220gr of material in order to print. You can find links for all the parts in the description of the video below.Īlso you are going to need some filament. ![]() The parts needed in order to build this project are the following: ![]()
