The IR Sensor boards finally arrived! We are busy soldering components, writing new Arduino sketches to show off the capabilities of these boards, and preparing for full blown production. New videos are in the works, for when we get back
Last week we connected a ICStation BME280 temperature / humidity / barometric pressure sensor to a a ICStation NodeMCU ESP8266. We displayed the collected data (along with Dew Point and Heat Index calculations) in the serial monitor. This week we
If we want to average a set of numbers, we add them together, then divide by the number in the set. 150 + 200 + 0 = 350 / 3 = 116 Average I’m using int and dropping the fractional parts. Use
Calling all Model Railroaders (ok, it’s not just for Model Railroading)! Remember our Scale Speedometer and Crossing Light project? We used IR transceivers in the track to detect a train passing overhead. Perfect for block detection and other projects. We
Two common ways of using a transistor is as an analog amplifier, or a digital switch. We are most interested in the digital switch mode of a transistor in our projects. Many times, an Arduino, or other microcontroller, is not
One of our favorite new toys is the ESP8266 WiFi module. A very powerful microcontroller in it’s own right, it’s easily programmed with the Arduino IDE, and uses the same code we have come to know and love. Update: Now
