In the image above, the circles seem to physically fall into the dent made by your fingers. Another application shows some rudimentary 3d modeling being done by physically … Read the rest
Sometimes a project has more sensors, buttons, or LEDs than your microcontroller has pins. The PCF8574 is an easy way to add 8 low-speed input or output pins to a microcontroller. A configurable address lets multiple PCF8574s exist on the same bus, so two microcontroller pins can control dozens of IO pins. We’ll show you how to use this chip … Read the rest
