We detect the door open with a hall sensor. We send the data to a database with the ESP8266. Then we send a mail to our own accoun so we could know that somebody opened the door from anywhere in the world.
Homemade display that uses Acrylic boards with engraved numbers and RGB LEDs from below in order to show all the numbers. You could connect them in series with WS2812 LED strip and create a digital clock.
Arduino based multimeter that could measure Inductance, current, capacitance, voltage and resistance. It can also detect short circuit, measure diode, frequency and more but that is for a furure update. See full schematic circuit and the PCB I've designed.
A 3D printed pumpkin with color adressable LEDs inside and a DF player for mp3 sounds. It also has a PIR detector so it will detect movements and then create spooky sounds. Is made with Arduino and also has a fog mist generator circuit of 1.7MHz.
This is a 7 segments display project. I say huge because is way bigger than comon 7 segment displays. Also, it is addressable so we can control a lot of themn in series using just one pin of the microcontroller and the Adafruit library.
I've remade this project. We have 9 dot matrix modules in series. We could scroll text sent from the smartphone via Bluetooth, we can show time from a RTC and the full date. Chaenge speed and brightness. See more...
We now have the radio controller made with Arduino. We have seen how to receive data and control servos. Now, with this PCB we can control DC motors as well, add sounds and more extra stuff. Also, we have bluetooth control with an Android App. See more...
