When you are controlling actuator that needs more than 5V or more than 40mA (this is the maximum current digital pins can supply), you can not directly drive this actuator from the digital pins. This is the case, when you want to use strong motor, embroidered speaker, SMA or any heat actuators.. and many more. […]
The arduino‘s analog pins are reading the voltage that comes in, not the resistance over the two points. When you want to use a resistive sensor (i.e. neoprene bend sensor), you need to manipulate the voltage that goes into the analog pins with the resistive change the sensor makes. For this, we can make a […]
