Learn electronics, coding, and projects — step by step.
In this article, I will tackle how you can use an Infrared receiver module with ESP32 using MicroPython. GorillaCell Infrared Receiver module from GorillaCell ESP32 development kits uses a VS1838 photodiode infrared receiver. It is low cost and easy to use.
In this article, I will demonstrate on how you can use an external WiFi module with ESP32 using MicroPython. Though ESP32 possesses a builtin Wifi device, sometimes an external module is necessary if you want to lessen the workload of the microcontroller.
In this article, I will discussed how you can use ESP32 BLE capability using MicroPython. Bluetooth Low Energy or BLE is very popular on most devices today because of its low power consumption. That is achieve by constantly switching to sleep mode then once in a while wakes up to process Bluetooth functions. With its low power requirements, it is best suited for battery operated applications.
In this article, I will show you on how we can use a Bluetooth Low Energy module with ESP32 using MicroPython. Bluetooth modules are useful for controlling applications such as in robotics or for displaying sensor values in IOT projects. BLE stands for Bluetooth Low Energy. It provides low power consumption because it stays in sleep mode most of the time.
