The ESP-07/ESP-12 is a generic ESP8266 module which have no bootstapping resistors on board, insufficient decoupling capacitors, no reset circuit, and no USB-serial adapter. This is an article shows you how to connect the bootstapping resistor to the ESP-07 module and upload sketches onto the ESP-07/ESP-12 using the familiar Arduino IDE.
A guide on how to use the L298N Motor Driver Controller Board, this is a dual motor controller board that allow you to control the direction & speed of two DC motors or one stepper motor.
The L298N Motor Driver Controller Board is a very low cost module, there are several design variants available on the market, mine get from GEARBEST.
This is a motor library for Lua running on wireless router which flashed with OpenWrt firmware. It allows a wireless router control the motors without using micro-controller. This library works on any dual-full-bridge driver such as L298.
Each motor require two GPIOs for controlling, therefore 2 motors will use up 4 GPIOs. Most of the wireless router may not have enough GPIO to control the motors, but you can use other pin on the router such as the LED pin, this require to unload the leds_gpio module.
I'm a Windows user and I always play with Linux on embedded system. Therefore I need a computer which is effective exchange of information between Windows OS & Linux OS.
This article provides information on how to install Ubuntu on Oracle VirtualBox with the following features:
- Run both Linux(Ubuntu) and Windows together.
- Sharing clipboard content between OS
- File sharing between OS
- Internet connection sharing
I want to built a wifi car without using micro contoller, due to the limited GPIO availability on the wireless router, a 74HC595 Shift Register is needed to expand its outputs.
This is a 74HC595 Shift Register library for Lua running on wireless router flashed with OpenWRT, it may run in any linux-based embedded system. It can be used to shift out data from either the most (i.e. the leftmost) or least (rightmost) significant bit.
