In this project we will see how a hydroponic greenhouse controlled by an ESP8266 was built. The system consists of pumps and temperature sensors controlled by […]

You set a dozen alarms in the morning, but still can’t wake up? In this project we will try to solve the problem in an alternative and quite creative way by building an alarm clock that will ask random questions. It will stop making noise only if the […]

Maybe a family member or friend. As they get older, many of them begin to forget things, some as important as taking their medicines. We could be reminding them or we could delegate this task to “Remind-ino”. The project is based on an Arduino Nano which thanks […]
