I made a rotary encoder using a IR sensor and a wheel with printed black and white spokes. Everything seems to work but I''m wondering if there is a better way to code this. The IR signal looks ideally like a square wave and I have it looking for the rising edge of each wave. Then calculate the time between rising edges to calculate the wheel''s RPM. int wheelPin = 11; // I/O pin for encoder int count = 0; // …

Arduino Hall Effect Sensor With Interrupts : 4 Steps Instructables

To connect the sensor on the Arduino, we will use a simple, yet very powerful feature called Interrupt. An Interrupt job is to make sure that the processor responds quickly to important events. When a certain signal is detected, an Interrupt (as the name suggests) interrupts whatever the processor is doing, and executes some code designed to react to whatever external stimulus is being fed to the Arduino. Once …
