Hey Guys -
I'm designing / building a project with minimal room for components which I have a few questions about, please. Below is a list of components, the latest sketch (also attached if it doesn't come through), and finally the questions...
Components
- Arduino Nano
- 5V Power Supply (PowerBoost 1000 + 3.7V Battery)
- x14 LEDs (Each in sketch counts as two wired together
- x7 330ohm resistors (x1 per pair of LEDs)
- Piezo Buzzer
- 330ohm resistor for Peizo Buzzer
- Servo (Standard / Micro)
- 0.96" Inch Yellow Blue I2c IIC Serial Oled LCD LED Module
- x2 Standard push buttons
- Probe Antenna (Wire with 3.3ohm worth of resistors connecting it to ground + A0)
- DHT22 sensor
- perf board /w horizontal rows for Arduino's GND + 5V
Questions
- Instead of connecting components to Arduino's 5V, would it be better to connect directly to 5V source?
- The probe wire is used to detect sensitive EMF. I'm worried that the 5V power plus cables will interfere. Any suggestions to try to isolate or shield it as much as possible?
- Any other suggestions for minimizing the space being used
Thanks!
