Our existing thermostat is a White Rogers that currently controls our Air Conditioner and Electric Furnace. We will be replacing this with our Arduino and LCD display. Attached are the photo’s, schematic, and documentation of the existing control. We will
We are building a thermostat to control our furnace and A/C. We are using a DFRobot LCD / Keypad shield we received from Hacktronics.com to display the temperature, and to set the temperature ranges for both the heating and cooling
We have produced a few more Mitutoyo to Arduino interface boards. This is a simplified version for a variety of micrometer and caliper to computer applications, from datalogging to CNC or milling machine control. Get the full code and schematics,
We have been playing with text to speech again. We used a Sparkfun voice box shield that includes the popular SpeakJet chip. The issue is that you have to code “phonetic” allophones to tell it what to say. It won’t
Our Amp / Watt Hour Meter (we need a snazzy name for it!) has moved from solderless breadboard to a more permanent protoboard. We have drilled holes all the way through the protoboard for the ring terminals to the load
I finished the carrier board for our tachometer project. This is simply the TCRT5000 IR emitter/sensor module, with the 150 ohm resistor for the IR LED, and the 10k ohm resistor for the phototransistor, as described in http://arduinotronics.blogspot.com/2012/06/reflective-optical-sensor-with.html I used
