Read moreThe APDS-9960 is a sensor that can be connected to a microcontroller such as the ESP8266 via the I2C bus. With the help of the sensor it is possible to […]
Read moreThe VL53L0x or its sister / brother, the VL53L1X is a very precise and relatively inexpensive laser distance sensor. With this, distances can be measured almost at millimeter-accuracy. In one […]
Read moreThe BME280 is one of the sensors that I use in almost all of my projects. With this sensor one can not only measure the temperature. The air humidity and […]
Read moreESPEasy can read out a large number of different sensors and / or control actuators (see also ESPEasy – Sensors & Actuators). With the help of the “Rules” it is […]
Read moreEspecially if your own circuit has a display to show values, the next step is often to connect an interface option. You can connect buttons or switches. A relatively cool […]
Read moreThe PCA9685 is quite a practical IC. This is connected to the microcontroller (e.g. ESP8266) via I2C and can then control up to 16 individual PWM channels. You can control […]
Read moreThere are some situations in which connecting an LDR to an ESP makes sense. In this way, the brightness in a room can be measured relatively easily and for little […]
Read moreThe PCA9685 is a PWM port expander. This makes it possible to connect up to 16 LEDs, servos or other components to your ESP8266 and supply them with a PWM […]
