Top 5 Wireless Ways to Communicate with your Controller

One of the strongest trend we have seen this year at CES2015 is, as you can imagine easily, the IoT (Internet of Things) development. Consequently, the most important component needed is the “connection and communication” module that enables the remote interaction between the device and “the community” via internet. Here we will sum up the various possibilities you can use to connect your controller using d ...

Control Loop Challenges of Wireless Systems

Automation is defined as using various control systems to operate equipment such that there is minimal human intervention. Closed control loops (feedback systems) regulate how other systems or devices behave by taking into consideration their output and making corrections based on feedback. An example of this feedback system is Progressive Automation Linear Actuators. In this article challenges of control l ...

Wireless Sensor Motor Control using PIC18LF4520

Last week we took a look at how you can wirelessly connect together two unrealted microcontrollers; an Arduino UNO and a PIC. The week before that we showed you how to build Motor Control via Distance Sensing. This week, let's combine the two project together to make a wireless IR proximity sensor that can control a motor's speed through a pair of XBee wireless modules. In this article, we will show you how ...

Bluetooth Wireless Voltage Meter using Wiimote + Pic Chip + AutoIt

In this tutorial I'm going to be showing you how you can send voltage values to your pc using a Pic chip, Wiimote, and Autoit3 scripting language. The process works by wiring a pic chip to the button pads of a wiimote. Then using the pic chips Analog to Digital Converter, we obtain a 10bit binary value. We will then send that value to Autoit in the form of button presses using the wiimote as a data interfac ...
