I want to know the method to stop Arduino mega 2560 reset when I upload program and open serial
monitor.
1.I tried use a 120 R connect with reset pin and +5v, but is did not work.
2.I tried use a 10uF connect with reset pin and GND, but is did not work.
3.I tried use a 100 R connect with pin 13 (connect with arduino and solenoid) and GND to pull down the Pin 13, but when I power arduino or upload program or open serial monitor, the solenoid still be on and off automatically
I hope the solenoid won't be on until the program ask it to do so.
could anyone help! thanks a lot !
