Anyone with even a casual familiarity with hobby electronics is likely familiar with H-bridge motor drivers. Named “H-bridge” for the H-like configuration of the 4 switching elements in the schematic, these drivers allow you to control DC motors for speed and to move forwards, backwards, left, and right.
In this DroneBot Workshop, they look at a number of popular H-bridge drivers and the types of DC motors they can control.
At over 1-hour, this is a great crash course in understanding and using this common drive train component.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
