To create a weather station module using the ESP32-DEVKIT-V1 (U2), BME280 (U1), and OLED 0.91" 128x32 I2C (OLED1), follow these wiring connections:
ESP32-DEVKIT-V1 (U2) to BME280 (U1):
  1. Connect 3V3 (U2) to VDD (U1)
  2. Connect GND (U2) to GND (U1)
  3. Connect D21 (U2) to SCK (U1) (I2C SCL)
  4. Connect D22 (U2) to SDI (U1) (I2C SDA)
  5. Connect GND (U2) to CSB (U1) to select I2C mode
  6. Connect 3V3 (U2) to VDDIO (U1) to set the I2C voltage level
ESP32-DEVKIT-V1 (U2) to OLED 0.91" 128x32 I2C (OLED1):
  1. Connect 3V3 (U2) to 5V (OLED1) (the OLED display can work with 3.3V)
  2. Connect GND (U2) to GND (OLED1)
  3. Connect D21 (U2) to SCL (OLED1) (I2C SCL)
  4. Connect D22 (U2) to SDA (OLED1) (I2C SDA)
These connections will allow you to communicate with the BME280 sensor and the OLED display using the I2C interface on the ESP32-DEVKIT-V1. You can then read temperature, humidity, and pressure data from the BME280 and display it on the OLED screen.

@copilot Can you wire my resistors R1, R2, and R3 in parallel to ground
2y

copilot

To wire resistors R1, R2, and R3 in parallel to ground, follow these steps:
  1. Connect one end of resistor R1 (P1) to a free point on the schematic.
  2. Connect one end of resistor R2 (P1) to the same point where R1 (P1) is connected.
  3. Connect one end of resistor R3 (P1) to the same point where R1 (P1) and R2 (P1) are connected.
  4. Connect the other ends of R1, R2, and R3 (P2) to the ground (GND) net.
After connecting the resistors in parallel to ground, the netlist should be updated to include these connections:
R1_P1__R2_P1__R3_P1,
R1_P2__GND,
R2_P2__GND,
R3_P2__GND,
Make sure to update the project netlist with these new connections.

Can you hook up my 8 leds to the ATMega328P-AU.
jlamflux

jlamflux

@copilot Can you connect U3 to my 8 LEDs without current-limiting resistors.
2y

copilot

Connecting LEDs directly to a microcontroller without current-limiting resistors is not recommended, as it can damage both the microcontroller and the LEDs. However, if you still want to proceed, you can connect the LEDs to the ATMEGA328P-AU (U3) pins as follows:
  1. LED1 (A) to U3_PD2 and LED1 (K) to Ground
  2. LED2 (A) to U3_PD3 and LED2 (K) to Ground
  3. LED3 (A) to U3_PD4 and LED3 (K) to Ground
  4. LED4 (A) to U3_PD5 and LED4 (K) to Ground
  5. LED5 (A) to U3_PD6 and LED5 (K) to Ground
  6. LED6 (A) to U3_PD7 and LED6 (K) to Ground
  7. LED7 (A) to U3_PB0 and LED7 (K) to Ground
  8. LED8 (A) to U3_PB1 and LED8 (K) to Ground
Please note that this configuration may cause excessive current draw and overheating, potentially damaging your microcontroller and LEDs. It's strongly recommended to use current-limiting resistors in series with each LED to avoid damage.

@copilot Can you hook up my 8 leds to the ATMega328P-AU.
2y

copilot

Sure, I can help you connect the 8 LEDs to the ATmega328P-AU microcontroller. Here's a simple way to do it:
  1. Connect the anode (A) pin of each LED to a free GPIO pin on the ATmega328P-AU.
  2. Connect the cathode (K) pin of each LED to GND through a current-limiting resistor.
Here's a suggestion on which GPIO pins to use for each LED:
  • LED1: Connect the anode (A) pin to PB0 (pin 14)
  • LED2: Connect the anode (A) pin to PB1 (pin 15)
  • LED3: Connect the anode (A) pin to PB2 (pin 16)
  • LED4: Connect the anode (A) pin to PB3 (pin 17)
  • LED5: Connect the anode (A) pin to PB4 (pin 18)
  • LED6: Connect the anode (A) pin to PB5 (pin 19)
  • LED7: Connect the anode (A) pin to PD5 (pin 11)
  • LED8: Connect the anode (A) pin to PD6 (pin 12)
For each LED, you'll need a current-limiting resistor. You can use a 330-ohm resistor for each LED to limit the current to around 10mA. Connect one side of the resistor to the cathode (K) pin of the LED, and the other side to GND.
Once you have made the connections, you can control the LEDs by setting the appropriate GPIO pins on the ATmega328P-AU as outputs and toggling their state in your firmware.

Can you just hook up U3 and all my 8 leds for me anyways?
2y

copilot

I apologize for any confusion, but as an AI text-based assistant, I am unable to directly modify your schematic or PCB layouts. However, I can still provide guidance on how to make the connections yourself.
To connect the ATmega328P-AU (U3) to the 8 LEDs, follow these steps:
  1. Open your schematic in Flux.ai.
  2. Connect the anode (A) pin of each LED to the suggested GPIO pins on the ATmega328P-AU (U3) as mentioned in my previous response.
  3. Add a 330-ohm resistor between the cathode (K) pin of each LED and GND.
  4. Make sure to connect all the GND pins to the ground net.
After making these connections in your schematic, you can proceed to route the PCB layout accordingly. Make sure to verify the connections before sending the design for production.

@copilot Please create the low-pass filter using V1, R1, C1, and ground. Wire it but do not use net portals.
2y

copilot

To create a low-pass filter using V1, R1, C1, and ground, follow these steps:
  1. Connect the anode of V1 to one end of R1 (R1_P1).
  2. Connect the other end of R1 (R1_P2) to one end of C1 (C1_P1).
  3. Connect the other end of C1 (C1_P2) to ground.
  4. Connect the cathode of V1 to ground.
Here is the low-pass filter circuit:
V1    R1    C1
--+--/\/\/--+--||--+
 |          |      |
--+---------+------+
  |                   |
 GND               GND
V1 is the DC supply, R1 is the resistor, and C1 is the capacitor. The output of the filter will be taken from the junction of R1 and C1.

To create a weather station module using the BME280 sensor (U2), the ESP32-DEVKIT-V1 (U1), and the OLED 0.91" 128x32 I2C display (OLED1), follow these connections:
BME280 (U2) to ESP32-DEVKIT-V1 (U1):
  1. VDD -> 3V3 (power supply)
  2. GND -> GND (ground)
  3. SCK -> D22 (I2C SCL)
  4. SDI -> D21 (I2C SDA)
  5. SDO -> GND (I2C address selection, pulled low for address 0x76)
  6. CSB -> VDD (SPI/I2C mode selection, pulled high for I2C mode)
  7. VDDIO -> 3V3 (I/O voltage supply)
OLED1 to ESP32-DEVKIT-V1 (U1):
  1. 5V -> VIN (power supply)
  2. GND -> GND (ground)
  3. SCL -> D22 (I2C SCL, shared with BME280)
  4. SDA -> D21 (I2C SDA, shared with BME280)
Once you've wired the components, you can use an ESP32-compatible library for the BME280 sensor and an OLED library for the display to create the weather station module.

    • Connect 3V3 pin on U2 to VDD and VDDIO pins on U1.
    • Connect GND pin on U2 to GND pins on U1 and OLED1.
    • Connect VIN pin on U2 to 5V pin on OLED1.
  2. I2C communication for BME280 and OLED:
    • Connect D21 (SDA) pin on U2 to SDA pin on OLED1 and SDI pin on U1.
    • Connect D22 (SCL) pin on U2 to SCL pin on OLED1 and SCK pin on U1.
  3. BME280 address selection:
    • Connect SDO pin on U1 to GND to select the default I2C address (0x76) for BME280.
  4. BME280 SPI/I2C mode selection:
    • Connect CSB pin on U1 to VDD (3.3V from U2) to select I2C mode.
Now that you have connected the components, you can program the ESP32-DEVKIT-V1 to read data from the BME280 sensor and display it on the OLED screen.

To create a low-pass filter using R4 and C1, follow these steps:
  1. Connect one end of R4 (P1) to the input signal.
  2. Connect the other end of R4 (P2) to one end of C1 (P1).
