Controllers and Sensors using arduino

John has been working to recover components from old power supplies and available trash electronics, in order to build controllers to power stepper motors and other mechanisms for the FabLab. Intro The Arduino microcontroller board is able to supply a current of 40mA from its output connections. These digital outputs are fixed at 5V “ON” or 0V “OFF”. This is adequate for working with LEDs but devices such a ...

Controllers and Sensors using arduino

Intro The Arduino microcontroller board is able to supply a current of 40mA from its output connections. These digital outputs are fixed at 5V “ON” or 0V “OFF”. This is adequate for working with LEDs but devices such as motors, solenoids, high brightness LEDs etc. may require much higher currents and voltages. To achieve this an interface in between the Arduino and the device can be made from locally source ...
