Pi Servo Hat Hookup Guide

Introduction The SparkFun Pi Servo Hat allows your Raspberry Pi to control up to 16 servo motors via I2C connection. This saves GPIO and lets you use the onboard GPIO for other purposes. Furthermore, the Pi Servo Shield adds a serial terminal connection which will allow you to bring up a Raspberry Pi without having to hook

Using Wemos D1 mini to control a brushless motor with ESC and servo signals

I’ve recently become interested in making “machines” of various sorts. I was sorting through some of my RC (radio control) plane “stash” the other day and came across various brushless motors and electronic speed controllers (ESC) like these. In RC, Brushless ESCs are usually connected to a radio receiver which generates servo control pulses. Turnigy

Raspberry Pi Control Motor Speed

Raspberry Pi Control Motor Speed

Controlling a motor is one of the most exciting things you can do with your Raspberry Pi. Motors are power-hungry components. They often require more power than the 3V3 your Raspberry can provide. That’s the reason we will connect the motor to a external power source (battery). You can use the same techniques described in this

Driving a bi polar stepper motor with the SN754410NE double H bridge and a Raspberry Pi

Driving a bi-polar stepper motor with the SN754410NE double H-bridge and a Raspberry Pi

Bi-polar stepping motors use only two coils and are easily recognized because they only have four wires. Most unipolar steppers can be used in bipolar mode by ignoring the two centre taps. Because bi-polar stepping motors produce the rotating magnetic field by reversing the current in both coils, controlling them is much more complicated than
