Hello, I am working on a project which has mechanical and electronical parts. I can do mechanical parts but need help for below part. Need a time lapse device , which can move a rc servo 90 degrees one time. Preferably adjustable for 5 , 10 , 15 minutes.. If it os very difficult only 5 minutes. For example , if we set it now , than it outs down to adjusted minute and than moves rc servo than stops..no more movement required. One time only. If possible it should work on 9volts or lower voltages.. Thank you for all, hoping to get a simple but working plan..
