In this tutorial we’re going to show you how to build a web server with the ESP32 that controls the shaft’s position of a servo motor using a slider.
First, we’ll take a quick look on how to control a servo with the ESP32, and then we’ll build the web server. Watch the Video Tutorial and Project Demo This guide is available in video format (watch below) and in written format (continue reading). Parts Required For this tutorial we’ll use the following parts: You can use the preceding links or go directly to MakerAdvisor.com/tools to find all the parts for your projects at the best price! Connecting the Servo Motor to the ESP32 Servo motors have three wires: power, ground, and signal. When using a small servo like the S0009 as shown in the figure below, you can power it directly from the ESP32. But if you’re using more than one servo or other type, you’ll probably need to power up your servos using an external power supply.

The most recent project I decided to work on was a line following robot. However, as I was testing it to make sure the direction code was working, I decided to develop something that I can control from my smartphone. It turned out much better than I was expecting, so I figured I should make a blog post about it. As you can clearly see, I pieced together the parts for my car.
Part List: Programmer131/nodemcuCar: modified version of. Arduino capacitive proximity sensor. Overview In this post I explain a capacitive proximity / touch sensor for Arduino based on a square wave generator rather than charge time measurement as the popular CapSense library.
This design results in very stable sensor readings and it also works from a battery. It is compatible with virtually every Arduino board and even with most ATtiny chips. How it works It uses the very same technique as the beautiful musical instrument, the theremin, only it operates on a much lower frequency (around ~60KHz instead of some MHz) and uses square-wave signals for the sake of easier counting.
By using an alternating current of suitable frequency, tones of varying pitch are easily obtainable. In summary, stable, ~60KHz square-waves are generated by an RC oscillator.

A common use for IoT devices like the ESP8266 is monitoring sensors.
Using the code in the previous example, we can request the time, and save some sensor values to a file. If we run a server as well, we can show this data in a pretty graph in a webpage. Connect the ground of the DS18S20 temperature sensor (pin 1) to the ground of the ESP, connect the data pin (pin 2) to GPIO5, and VCC (pin 3) to the 3.3V of the ESP. Finally, connect a 4k7Ω resistor between the data pin and VCC.
The only new things here are the OneWire and DallasTemperature libraries, to get the temperature from the sensor. In the setup, there's not much new either, we just start the temperature sensor, and check if we can communicate with it. Getting the temperature from the sensor may take some time (up to 750ms). Loop The loop looks a lot more complex, but it's actually pretty simple. There's two things going on: How to Get Started With ESP8285 Module ?
