An ESP8266-based peristaltic dosing pump
thingiverse
A WiFi-enabled peristaltic pump powered by a NodeMCU / ESP8266-12E microcontroller, a NEMA-17 compatible stepper motor, and an EasyDriver driver board. This is a refinement of another user's design to be much more reliable, and was tested over many iterations until it worked flawlessly. See the remix for the original design. Firmware provided to allow easy WiFi management and control of the device over MQTT technology as well! A CoogleIOT based firmware is also provided which uses the AccelStepper library to provide control of the doser over MQTT available for download here: https://github.com/ThisSmartHouse/coogle-doser
