We can control a servo using ESP IDF LEDC API. We have already seen how to do that here. The servo sweep program changes the angle of servo

ESP32 has three hardware UART controllers (Serial ports) , UART0, UART1 and UART2. All three UART controllers are independent and fully featured (configurable parity bit, baud rate etc.).

When Bluetooth stack is enabled in ESP-IDF, the default behavior is to connect to previously connected Bluetooth device. We can reset (erase) all the bonded devices data to

ESP32 is fun to work with, once you got it into a network, you can do lot of things. We have seen how to make use it as

How long it gonna take to build a simple end-to-end IoT application ? , lets find out. In next couple of blogs I will try to build a

In this post we will try implement the second iteration solution that we discussed in previous post. Read the previous post for setup instructions. In first iteration we did not had

Servos are exciting devices. We can get precise posting with minimal code, all you need is a controller that can produce PWM at 50Hz. In this post we

The standard ESP32 module (ESP-WROOM-32) present in the market has 512KB SRAM. For most the applications this RAM is more than sufficient. In fact it is nearly 4

We have already seen how to connect arduino uno to NodeMCU (ESP8266) here . In this blog we connect Arduino UNO with ESP32. When connecting UNO with nodemcu we
