The SHT1x digital humidity sensor is a reflow solderable sensor. The SHT1x series consists of a low-cost version with the SHT10 humidity sensor, a standard version with the SHT11 humidity …

The bar graph is basically a series of LEDs in a line, this is a common hardware display for analog sensors. It’s made up of a series of LEDs in …

This sensor is obsolete now and has been replaced by newer ones but if you still have them lying about then this is how to connect them up to an …

In this example we will show you how to perform a software reset on the ESP32 using the Arduino IDE. Luckily the ESP32 has a method in its library that …

In this example, I will show you how to apply FreeRTOS in Arduino ESP32. Arduino ESP32 is built over FreeRTOS and actually the main program is put in a loopTask …

This example uses an OLED display these typically come in a couple of different sizes 128×32 and 128×64, this particular example will use the I2C connection from the Micro:bit to …

In this example we connect a photoresistor to a ESP32 Lolin32, the value read from the photoresistor corresponds to the amount of light present. The photoresistor is connected to A0 …
