Programming Raspberry Pi Robot: Making it Follow the Lines ...

Extended Code of the Raspberry Pi Robot. In order to follow the line, there are different modes that are checked: If both sensors detect the line, it is simply driven straight ahead, if only one of the two sensors detects the line, it is driven a little in the other direction. As soon as both sensors detect something again, the vehicle will drive straight ahead again. If neither of the two ...

Raspberry Pi: Control Relay switch via GPIO

Often you want to control modules with a higher voltage with the Raspberry Pi. For this purpose, relays can be used on the Raspberry Pi: The relay “switch” is utilized by means of a lowvoltage pulse. Since the Pi only tolerates a maximum of 5V (the GPIOs even only ) without relays, there is the risk that the Pi could burn out. However ...
