| Nov 25, 2019 at 20:53 | comment | added | JDS | Nvm regarding generating voltages, these devices I found solve my problem well: amazon.ca/gp/product/B00BYTEHQO/… (in case others are interested) | |
| Nov 25, 2019 at 20:43 | comment | added | JDS | Thanks, and what are some simple ways of generating the 5V,6V,7V lines? Also - what happens when GPIO1,GPIO2 == (0,0), (1,0), (0,1), (1,1) ? (1,0 being logic equivalent of 3.3V, 0V that the RPi provides) | |
