In addition, we will build an Arduino OLED Temperature and Humidity Meter using an OLED and an I2C temperature and humidity sensor.Read More » Experiments with the RCWL-0516 - Doppler Radar Distance Sensor The RCWL-0156 is an inexpensive yet useful proximity sensor that can be used on its...
Sticking my multi meter directly up the USB port in the desktop gives me 5.11V. You need 6.5V or so to get the on-board regulator working properly. If you power the board from an external power supply of 7 to 12 V on the VIN pin, the onboard regulator would be used and you may...
Simple 3 Phase Arduino Energy Meter: Since writing up instructions on how to build a simple Arduino home energy meter which measured the energy consumption for a single phase, I’ve had a number of people ask about modifying it to be a 3 phase energy met
DC/AC secondary relay - like SLA-05VDC-SL-C (240V/30A) mechanical relay Additional MAX31855 board with K-type thermocouple for housing temperature measuring Coil power meter - 30A/1V. This is contact less power meter that generates small current when energy flows inside it's coil. Mine alre...
