There are rumors of a cheap chip that does USB natively, has an Open Source toolchain, and costs a quarter. These aren’t rumors: you can buy the CH552 microcontroller right now. Surprisingly, there aren’t many people picking up this cheap chip for their next project. If there’s no original projects using this chip, no one […]

For the long series of articles documenting My Journey into the Cloud I used two small evaluation boards, equipped with an ESP32 32-bit controller, an antenna and a micro USB socket (the latter also serves for power supply input and provides a path for uploading programs). For newcomers, the controller can be programmed using the

The ESP8266 WiFi Module is a self-contained SOC that can give any microcontroller access to your WiFi network. It’s an extremely cost-effective board with a huge and ever-growing community. Each ESP8266 module comes pre-programmed with an AT command set firmware. This module has a powerful on-board processing and storage capability that allows it to act as a

I built a very simple DIY solar-powered USB charger for my TP-link 10400mAh USB Power Bank. All I needed was a 6V/3.5W solar panel and the TD1410-based 5V buck converter module. I bought both of them on Aliexpress for less than $8. It was one of the easiest projects I built. All I needed to do was to connect

Now that the PC’s com port or Serial port is almost obsolete there is quite a lot of requirement for USB to TTL or USB to RS232 converter. USB to TTL converters are required for interfacing microcontrollers to PC it is also required for loading code in Arduino Mini, setting/modifying ESP8266 firmware. Over here we

This instructable shows how to control some servomotors remotely in a wi-fi network, using an ordinary internet browser (Firefox, for instance). This might be used in several applications: toys, robots, drones, camera pan/tilt, etc. The motors were attached to an Arduino Uno, which connects the wi-fi network through a ESP-8266 module. The control interface was

Step 1: Introduction Description: Bipolar Stepper Motor is DC motor that move in discrete steps. It has multiple coils that are organized in groups called “phases”. By energizing each phase in sequence, the motor will rotate, a step at a time. In order to be able to move the motor, you will need a motor
