You can read the encoder independently and transmit, the collected, data through the I2C protocol. Otherwise you can control directly a crown of neopixel LEDs from the attiny85 micro controller. This ...

For fun, and because optical encoders cost an arm and a leg. Initial BOM for 10 pieces places this thing around the price of a mechanical encoder. None of this is tested yet.

You know, we hadn’t realized how tired we were of vertical laser harps until we saw [Jonathan Bumstead]’s entry into the 2019 Hackaday Prize. It’s all well and good to imitate the design of the ...

Is it really possible to build a rotary encoder out of a flattened tin can and a couple of photodetectors? Sure it’s possible, but what kind of resolution are you going to get from such a contraption?

Across a wide range of applications, it is necessary to accurately sense the motion of a rotary shaft and know its position, speed, or even acceleration. To do this, a shaft or rotary encoder is added ...

Encoder sensors are a type of mechanical motion sensor that create a digital signal from a motion. It is an electro-mechanical device that provides users (commonly those in a motion control capacity) ...
