I am VERY new to electronics and the MSP430 so please forgive my ignorance. My friends and I started up an electronics club a couple months ago and our first group project we are doing is a Rube Goldberg machine. The only stipulation is you get a 5volt power in do something with it and give 5volt back out. my particular project is the following.
1st msp430
receive 5volt
activate 3 sets of leds red, yellow, green
activate a servo that flips a switch to turn on a slot car
2nd msp430
count number of laps by car
once 5 laps have occurred light up 3 sets of leds
activate a servo that flips a switch to send my 5volts to the next part of the machine.
My question is this. I want power the entire time to my msp430's. I have an IF loop running waiting for button press "pinMode(buttonPin, INPUT_PULLUP); " then it lights the lights and runs the servo.. I set this up for testing. I need to remove the button and replace it with a voltage signal on my pin instead of going to ground. Is there a way to do this?
I know I can just use the 5volts to turn on my msp430 and run without the IF loop but I want to see if I can do it this way.
Again I am VERY new to this so I hope I gave enough information.
