Review on 🔧 Enhanced Performance with DIYmall 0: The Ultimate DIY Electronics Tool by Richard Simmons

Works well after a little reading. I found that you do NOT need to set up a header file, just initialize the display with display.begin(SSD1306_SWITCHCAPVCC, 0x3C); Works on both Uno and Mega devices Uno PinoutSDA - A4SDL - A5GND - GNDVCC - 5vMega PinoutSDA - 20SDL - 21GND - GNDVCC - 5v Sample code for SSD1306 starts pushing the Uno's memory but Mega has no problem with it, to load the program. Being an OLED, it looks dead until initialization, which can be a little confusing when testing the screen for the first time. I thought I had a dud until I initialized it properly. There were no problems with 3.3V or 5V. Tested with a 30kΩ thermistor. );#if (SSD1306_LCDHEIGHT != 64)#error("Invalid height, fix Adafruit_SSD1306.h!");#endif#define THERMISTORPIN A0 //which analog pin to connect#define THERMISTORNOMINAL 30000 //resistance at 25 degrees C #define TEMPERATURENOMINAL 25 // temp. for nominal resistance (almost always 25 C)#define NUMSAMPLES 50 // how many samples to take and average, more takes longer#define BCOEFFICIENT 4400 // thermistor beta coefficient (usually 3000-4000)#define SERIESRESISTOR 30000 //" other" resistance values [NUMSAMPLES]; void setup() { Serial.begin(9600); //connect AREF to 3.3V and use it as VCC, less noise! analog connection (EXTERNAL); // By default we generate a high voltage from the 3.3V line inside!
