🦊 Wemos D1 Mini I2C Example

According to the pump data, it should take 0.12 A when powered at 3.3 V or 0.18 A when powered at 5 V. I powered my micro-pump with 3.3 V and use a digital multimeter to verify the running current and it shows, indeed 0.12 A. When reading the ADC pin, I get values around 120 (they are varying between 100 and 140 with some peaks of 160.) Wemos D1 Release 1 (R1) and Release 2 (R2) . Here you can find information for the big brother of the Wemos D1 mini which can be found here. R1 vs. R2 - The Difference ; When you take a look at the figure 1 you will see it with one blink of the eye thet the old Wemos is different against the new version R2. The box and the prototype PCB is optional, only one ESP8266 based MCU is needed and one DS18B20 temperature sensor. I suggest to you a WEMOS D1 mini, but this example works with an ESP-01 as well. This example does explain how to write and upload an Arduino program to the ESP8266 MCU, so be aware of this skill before following me. Unlike an Arduino Micro, the Wemos D1 mini is equipped with WiFi hardware at a price that is more than excellent. Wemos D1 Mini has 11 digital I / O pins, 1 analog input only and all I / O pins operate with a 3.3V supply voltage; the available memory is 4MB. DHT11 is a composite humidity and temperature sensor module. Got an odd one. WeMos D1 R1. The first sketch is a test to determine the best LED flash patterns to allow me to test two different events from across a room (or farther). I used the same includes as the EspNowSlave.ino, and structured the LED code in the same way. This test works fine. In anticipation the Wemos D1 mini is fubar, I have looked online for a replacement. The one supplied with my kit looks like this: All listed replacements (eBay and AliExpress) have a different 'top' side: 773×600 84.8 KB. Perhaps crucially the other side has an RF can, which mine does not: 798×557 84.8 KB. This is the first simple project we are going to create using the Wemos Mini and various shields. In this particular example we are going to simply display temperature and humidity readings from a DHT11 sensor on an OLED display. These are all shields making this a simple project to build. Requirements. 1 x Wemos Mini 1 x Wemos Dual Base 1 x WEMOS D1 mini ESP8266 project Project Owner Contributor Wi-Fi signal strength LED indicator Using Wemos D1 minis, I2C temperature sensors, 7-segment displays Hello all, I am having a bit communication issues with i2c sensors. Below are some examples. MPL3115A2 connected to an ESP8266 (Wemos D1 mini). Despite the sensor being discovered, the communication fails. The VL53L0X is a new generation Time-of-Flight (ToF) laser-ranging module housed in the smallest package on the market today, providing accurate distance measurement whatever the target reflectances unlike conventional technologies. It can measure absolute distances up to 2m, setting a new benchmark in ranging performance levels, opening the door to various new applications. The VL53L0X […] The I2C bus must be instantiated using the machine module. 4.1 The EEPROM class . An EEPROM instance represents a logical EEPROM: this may consist of multiple physical devices on a common I2C bus. 4.1.1 Constructor . This scans the I2C bus - if one or more correctly addressed chips are detected an EEPROM array is instantiated.
