Are you wondering how the new MPLAB LCD 4 In-Circuit Programmer compares to the MPLAB lCD 3?
Then check out this article published by DesignSpark:
Following on from the MPLAB® ICD 3 - the much loved and most popular production programmer for Microchip - comes the New MPLAB® ICD 4 in-circuit debugger/programmer launch...
In the previous tutorial, the Constant Current (CC) Source of 60 mA and Constant Voltage (CV) Source of 4.2 V were designed using LM317 voltage regulator IC. The constant current source is to be used for constant current mode of the battery charging while the constant voltage source is to be used for constant voltage mode of the battery charging. During the designing of constant current source and the constant voltage source, testing a Li-ion battery before charging it was also discussed. Check out the previous tutorial “Basics of Li-ion battery charging” for learning about the basics of Lithium ion batteries, their charging methods and topologies.
Smoking and alcohol are hazardous to health. Also, the consumption of alcohol is one of the reasons behind many anti-social incidents. That is why, smoking and consumption of alcohol is prohibited in many areas like it is prohibited in schools, colleges, hospitals and public transport like buses and trains. In fact, these kind of activities must be prohibited in all kind of public places. Despite rules of prohibition, there are many incidents when people are found not abiding the rules. In such case, for law enforcement, there must be some system to detect infringement of such laws and the authorities must be sent an alert at time.
Texas Instruments, a global semiconductor design, and manufacturing company has unwrapped the company’s first robotics solution for middle and high school students rendering an enhanced experience of learning STEM subjects. Students will now be able to write programs on their IT graphing calculators that will get the Rover’s wheels turned. This would help their minds learn things in a fun, interactive way.
In one of the previous projects "Hand Gesture Controlled Wireless Robot", it was discussed how remote controls with switches or buttons used for controlling wireless robots have a disadvantage in controlling the robot due to response time factor of the human handling it.
In the previous tutorial, the basics of Lithium ion batteries were discussed. Also, it was discussed how it is important to handle these batteries with care. as mentioned in the previous tutorial, that Lithium ion batteries need to be charged using CC-CV method, in this tutorial, a Li-ion battery charger for a single-cell Li-ion battery of nominal voltage 3.7 V will be designed. 
The wireless robots are controlled in many ways. Usually, these robots are controlled with the help of a remote control which connects with the robot via Bluetooth, Wi-Fi or RF interface. The remote control has physical buttons to move the robot in different directions.
In this tutorial, a constant voltage charger for the 12V lead acid battery will be designed. The lead-acid batteries can be charged in different ways or modes. In this tutorial, a constant voltage charger will be designed for charging the lead-acid battery. The battery is required to be supplied limited current which saturates once the peak terminal voltage is achieved in the charging process.
The Uninterruptible Power Supply (UPS) is an electronics device which supplies power to a load when main supplies or input power source fails. It not only acts as an emergency power source for the appliances, it serves to resolve common power problems too. Any UPS has a power storage element which stores energy in the form of chemical energy like the energy is stored in batteries.
An autonomous robot is a robot that is capable of moving on its own in an unknown and unstructured environment. An autonomous robot is equipped with software intelligence to sense its environment, detect obstacles in its path and move around an unknown environment overcoming the obstacles.
