Arduino Nano 0.96" OLED display (I2C) MAX9814 microphone module Breadboard and jumper wires 1x Capacitor and resistors (as needed for the microphone module) Power supply (USB or battery) Circuit Diagram Below is the basic connection diagram for the project: MAX9814: VCC to 5V on Arduino GND...
Now, as we have connected through a WebSocket connection, if the DHT sensor data or the LED status changes, the changes will be reflected on the phone, also we can observe the changes on the OLED display. And sure enough, when we click the 'on and off' button, the data on the...

Interfacing Soil Ph Sensor with Arduino & OLED Display Now, let usinterface the Soil Ph Sensor with the ArduinoNano Board using theMAX485 Modbus Module. The connection diagram is given below. TheR0 & DIpin of from the Modbus is connected toD2 & D3of Arduino using Software Serial. Similarly...
Arduino was already running short on PWM IO and I needed to double up on the outputs. Fortunately, someone pointed me in the direction of these PCA9685 16 channel PWM drivers, so I used them and a DS1302 real time clock module to build a mechanical 7 segment display clock which uses ...
I would like to ask, if it is possible to use the OLEDs LCD Screens (like "https://www.google.com/search?q=I2C+OLED+Display+Module+0.91+Inch+I2C+SSD1306+OLED+Display+Module+White+I2C+OLED+Screen+Driver+DC+3.3V~5V+for+Arduino&sxsrf=ACYBGNSXs3GW3uR3rALhh1RaHq_1nvBwdA:1575650266095&...
2) Now you can enable the built-in OLED display with this line Heltec.begin(true /*DisplayEnable Enable*/, false /*LoRa Enable*/, true /*Serial Enable*/); 3) The key to getting I2C to work seems to be that now you have to initialize the display then other devices can be used He...
After playing with the OLED's, I've concluded they are fine for small projects like Time and Temperature...etc But, I'm sticking with TFT's. I went back to my standard approach for coding TFT-display's usingdtostrf(Alt, 7, 3, stringBuff1)and printing the buffer. Works Perfect! Zero...
