Voltage, current, temperature and date/time monitor using Arduino pro mini (ATmega328P). Data is recorded every specific range of time (this case every 30s), saved to a microSD card and shown in a ...

The system was used to monitor an 12V uninterrupted power supply (UPS) charge and discharge cycles. A total of 2426 data where taken. The system was executed for around 20 hours and data were recorded ...

[Credit: Invent Geek] Gardening can be quite rewarding, but it can also take up a quite a bit of time. There is software out there that can make it easier to monitor your garden, but if your plot ...

CGA monitors may not be an amazing technological advance these days, but they can generally be found very cheaply. Additionally, they have a DB-9 connector and work off of TTL ranges (0-5VDC) makin… ...

Here, we’ll learn how to interface an AD8226-based EMG sensor with Arduino UNO and plot the electrical activities of a muscle group on Arduino UNO. The sensor can be used to measure the activation of ...
