I've got an Arduino now and I was building lights the last weeks to understand the coding. But when it comes to use full stuff I could do my mind is empty. Do you have any suggestions for me?

I know there have to be FUCKs in a good rant. So I will miss use the tags...

How about automating a greenhouse? Light, humidity and temperature sensors and a couple of relays should do the trick.

Oh yea, quite a bit of testing, debugging and, of course, coffee.

One project i will do is controlling a stepper motor reading the commanded position via spi...
Maybe stealing some code from marlin (firmware used to control a 3d printer using a arduino 2)

Make a robot that high fives you

Look at all those fucks! +1

@devios1 @Letmecode Merci 😅

@Letmecode totally agree, the tags deserve a ++

My personal projects (all connected to a central server using wifi):

- Per pixel programmable RGB lighting throughout the house, about 100m. Eats a few kilowatt at full brightness, powered with 6 PSUs, controlled with a dozen arduinos to reach desired addressing speed for 14400 leds. Must have that cheap brothel look.

- Solenoids on pexfit water conduits so I can remote fill the bath tub from my phone (a small arduino, a thermostat, two solenoid valves and a moisture detector in the overflow for shutting off)

- Light switch and dimmer states through the house can all be read & set from server, web interface and phone (few dozen ATtiny chips with data lines throughout the house)

- Alarm system for air quality, gas leaks, etc. (5 arduinos with detectors, speakers, and wifi)

- Small aquaponics setup with two tilapias, bsf larvae composter and some herbs. (shit load of sensors and a Raspberry pi)

- Dishwasher, laundry machine and dryer have a rest API for querying state and starting them (custom flashed ATtiny chips wired to the PCBs, with some dremel/3d printer help, on wifi network)

- At work I have this obnoxious large led matrix which shows the latest unit test run.

- Solar charged battery pack in bike frame with automatic bike lights, plus gps pinger which shows bike location using m2m/iot sim card.

Room automation

Some cool ideas, I will wait for more. 🤗

Make a solution with a webcam that opens the front door for just your face

@Tytanium what is lifi?

@Divisionbyzero Wifi through light afaik

Get some neopixels off of adafruit, they are fun to play with.

If all you have are some buttons, wires, and LEDs, make a Simon game =D
