Bosch has a new, very accurate all in one sensor chip that does Temperature, Humidity, and Barometric Pressure readings. It’s called the BME280. Embedded Adventures has put that chip on a handy breakout board with signal conditioning (MOD-1022) and priced
I love RGB LED’s. One little module can produce a wide spectrum of colors just by varying the signal on the red, green and blue pins. I also love my TV remote, as I am a bit of a couch
We just picked up a LIPO shield from Adafruit, which allows us to battery power our projects. The shield contains a optional 2Ah LIPO battery, and recharges from a mini usb cable (same as a Kindle). You can power your
We wanted to save energy, and create convenience, by adding motion sensors to our lighting circuits. Maybe you want some notification of an intruder. Both can be done with a PIR Motion sensor. When I walk into a room, the
This data logger monitors a solar or wind off -grid power system. A current shunt and voltage divider monitors the voltage and current of the system. This data is displayed on the LCD and written to the SD card along
One of the least expensive and simplest ways to measure temperature is with a LM35. This is another component found in our SainSmart kit. This transistor looking device has 3 pins, 5v, Signal out, and Gnd. The signal is an
