this is called smart parking its a mini functioning parking gates like in malls and hotels and those type of parking gate using a Micro:bit. Micro:bit extension, servo motor, IR (infrared) sensor and wires to connect from the micro:bit extension to the sensor and the servo, we also get a mini parking zone to try the smart parking. How it work is that if an object is in front of the sensor or the sensor detect something it will send a signal to micro:bit and the micro:bit will make the servo move and open the gate
