Arduino Internet Time Client

UPDATE! Added 12h/24h switch and Standard / Daylight Savings Time Switch! See steps 7 & 8. Typically computers get their internal clocks adjusted by connecting to a Network Time Server (Internet or Local), using the Network Time Protocol (NTP). That functionality is also available to microcontrollers like the Arduino. We have put together an inexpensive …

Water / Chemical / Fuel level Sensors

eTape™ Continuous Fluid Level SensorThe Next Generation of Liquid Level Sensor Technology The eTape Liquid Level Sensor is a solid-state sensor with a resistive output that varies with the level of the fluid (liquid or powder).  It does away with clunky mechanical floats, and easily interfaces with electronic control systems.  The eTape sensor’s envelope is compressed by the …
