M5Stack has produced some amazing hardware. I recently got my hands on M5Stack Core2. Its compact, powerful and well built. It has plenty of Flash and PSRAM (16MB

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
