Project description

Code

Car Counter Full Code

arduino

This code counts each time the pressure sensor is triggered

Car counter pressure test

arduino

This code allows you to see that the pressure sensor is working. It's just the main code with some bits commented out.

New! Overnight sleep

arduino

I've added a few lines and rearranged the code so the arduino goes to sleep at night, as we are only open 10am - 5pm. This saves a bit of battery! you need to physically connect pin 2 on the arduino to the alm or int pin on the RTC.

This is a rough approximation of the circuit; the RTC and the pressure sensor aren't the models you use in my project but they have the same connections. (I'm rubbish at fritzing, half of the parts aren't in the library and nothing lines up with the holes. )
