Step 6AREF, +5Vs, and GNDs
We will continue to build out our ATMega circuit by adding power and ground connections. As you can see in the Pin Mapping:
- GND needs to go to pins 8 and 22.
- VCC (+5v) needs to go to 7, 20, and 21 (the analog reference voltage).
Go ahead and connect these pins to the outer terminal pairs directly across from them, using the appropriately colored wire.
- GND needs to go to pins 8 and 22.
- VCC (+5v) needs to go to 7, 20, and 21 (the analog reference voltage).
Go ahead and connect these pins to the outer terminal pairs directly across from them, using the appropriately colored wire.
