Testing even the smallest electronic components is easily performed using two miBot micromanipulators. In this example, we bring the required potential to light a micro LED (Light Emitting Diode). An electrical probe is mounted on the miBot arm. The first miBot micromanipulators is used to supply one of the LED electrical pads to a ground potential. Once this first miBot is in place, a second miBot micromanipulators is used to bring a 5 Volts potential to the second pad of the diode.
