Components
- Breadboard Power Supply Module IM120525004
- 1 kOhm resistor
- Green LED
- Arduino Nano
- LiPo 7.4V battery
LED Lights Up Fine with USB power from the Arduino
LED Does Not Light Up with power from the Supply Module
What am I doing wrong?
- The Lipo battery is brand new and is charged as the terminals showed about 7.6V on my multimeter. This is confirmed by the LED on the supply module itself lighting up fine.
- I think I can smell just a little bit of burn whenever the supply module is connected and there is power in the circuit.
- The positive jumper wire is connected to the 5V VCC pin on the Arduino, not the VIN pin on the Arduino, not that it matters, because if I remove the Arduino from the breadboard the LED still does not light up
