Rotary encoders are great devices. Monitoring just a few pins you can easily and quickly read in rotation and direction of a user input (as well as many other applications). But as with anything, ...
Absolute encoders using optical technology often face limitations in resolution and size. For example, to achieve a higher resolution of up to 16-bits, the absolute encoder has to be combined with an ...
As you might have noticed, the 38-KHz pulse generator is built around the evergreen timer chip NE555P (IC1). Here, the RC components (R5-C3-P1) set the astable frequency to drive the infrared light ...
