Hello,friend! I will share some idea about how to make a Arduino Multi-Function Bluetooth Smart Car.How do you like it?
The Arduino Bluetooth Smart Car fromhttp:// www.icstation.com has the function of Complete tracking, obstacle avoidance, infrared remote control and Bluetooth remote control. It is a MCU study and application development system base on Atmege328.The greatest feature is that you can control it with Mobile phone bluetooth of Android system. That’s may have a lot of fun.To make it, you need a number of kits which contain a number of interesting programs, and expand external circuit module to implement functions.
You can know more details from http://www.instructables.com/id/Inst...ion-Smart-Car/where I post.
ICStation Team share this LM2596 Step Down Power Module with you in details. We will introduce the features,scope of application,diagram,and testing results.We use the digital storage oscilloscope to test the module and show you the actual testing results with pictures.You will have a full understanding of this module.
1.With voltage meter display;voltage meter error of ±0.1V;the range among 0~40V. (note: to ensure the voltage meter accuracy, please make sure that the input voltage is 4.2V or more).
2.Voltage meter can be closed by long pressing button(minimum power loss).
3.The range of input voltage is 4.2~40V and output voltage is1.25V~37V ,which are continuously adjustable.(The input voltage must 1V higher than output voltage)
4.Maximum output current can be as high as 3A,but normal and stable working current is2A.
5.Use 150KHZ internal oscillation frequency,which is belong to the second generation of switch voltage regulator with low consumption and high efficiency.
Where to use:1.experiment teaching 2.temporarily set up power supply in the outdoor 3.car(audio, electric fan)power supply
What is special:LM2596 Step Down Power Module design based on XL2596 as main control chip,attached digital tube to display voltage at that time to highlight smart function. What’more, schottky diode provides protection of reverse connection.
