Interfacing of MQ-135 Gas Sensor with Arduino

Stepper Speed Control. Stepper motors, due to their unique design, can be controlled to a high degree of accuracy without any feedback mechanisms. (or other sensor) on analog input 0 is used to control the rotational speed of a stepper motor using the Arduino Stepper Library. The stepper is controlled by with digital pins 8, 9, 10, and 11

Ketosense – An Arduino based ketosis detector. The Arduino then divide it into 1023 parts so the value I actually read from the sensor is a voltage where every step is a change of 5/1023 = 0,0048V. Another application for this device is actually a breath alcohol detector, since the sensor is actually sensitive to ethanol as well as

DIY Digital Hydrometer Project. 01 Mon Aug 2016. Posted by diy brewer in Digital Hydrometer, Projects ≈ 10 Comments. I intend to base the project around the Arduino, probably the Uno (due to the low price of Uno clones available). Add on an accelerometer to measure the angle of tilt, a wifi shield to send the data, and a battery pack to
