Hello, firstly I am a complete novice with an idea that may or may not be possible, hence I signed up to the forum for help. I would like build a circuit which will light up a green light if, at the moment pressure is released from a pressure sensor, the height of two points A and B are level. The best way I can explain it is imagine you are holding a ball in each hand and at the same time you have your foot on a pressure sensor. When you release your foot from the sensor a green light will illuminate if the balls in each hand are level with each other. It will illuminate red if the balls are not level. Lastly the sensors etc need to be micro if possible. I’ve looked around but I honestly don’t know where I should start.
