ARDUINO TUTORIAL #10

PRACTICE EXERCISE

Use a jumper wire with connectors at both ends. Connect one end to the junction between R1 and R2 (the end of R1 or the beginning of R2) to measure the voltage across R2 relative to GND, specifically U2.

Connect the other end to one of the analog pins (A0–A5) on the Arduino.

IMPORTANT NOTES:

• To measure voltage using Arduino, connect one end of the jumper wire to the point in the circuit where you want to measure the voltage relative to GND.
• The other end MUST be connected to one of the analog input pins (A0–A5).
