/* PUSH UP COUNTER

An ultrasonic sensor measures the distance between you and your head, if the distance is larger than 20 cm a rgb-led will shine red, if the distance is between 10 and 20 cm, it turns yellow and if it is less than 10 cm it turns green, and a point appears on a lcd screen. Every ten pushups it makes a sound. You can reset the score with the push of a button. */ #include // include LCD library
