In this project we will control a DC motor with a smartphone via bluetooth. This project is great to learn more about:.
Jul 8, 2018 - Temperature controlled room cooler, ceiling Fan and Exhaust fan. NOTE: If using a board with 3.3V logic like an Arduino Due connect pin 1.
DC motors. Interfacing Arduino with your smartphone. Bluetooth. L293D IC If you don’t have the L293 IC you can make the same circuit using the H bridge, anyway I really recommend you to read more about that and the IC datasheet.
There’s plenty of tutorials about that. Also If you don’t have a bluetooth module yet So Let’s start Parts required. – read. 1x Smartphone (any Android will work).
BlueTerm application. 1x L293D IC.
You can use the preceding links or go directly to to find all the parts for your projects at the best price! ENROLL IN: I can only TX and RX cables after you upload the Arduino code. Two common mistakes. You need to remove the RX and TX cables when you’re uploading the sketch to your Arduino. Sometimes people connect the TX from the bluetooth module to the TX of the Arduino that’s wrong and it won’t work. Make sure you connect it properly, the TX into RX and the RX into the TX. Note: If the HC-05 Bluetooth Module asks for a password, It’s ‘1234’.
Upload this code below Make sure you remove the wires from RX and TX otherwise the code won’t upload properly! For the android communication with our bluetooth module I’ve used the BlueTerm app, It’s completely free, so you just need to go to “Play store” and download it. Then you just need to connect your smarthphone with the bluetooth module. Remember to remove the TX and RX cables.
(you can see in youtube video below how that’s done). I’ve only set 3 commands to control the DC motor:. ‘0’ – Turns off the DC motor. ‘1’ – DC motor rotates to right. ‘2’ – DC motor rotates to left Watch the video demonstration.
Hello friends, hope you all are fine and having fun. In the previous posts, we have discussed and after that we have discussed the and finally we had a look at. Now when you talk about motors control then first thing came in mind is Relay, because relay is the best way of controlling any motor. In today’s post, we are gonna have a look at How to Control Relay in Proteus ISIS. Relay is a key components of any electronics or electrical circuit and is usually a problem for the engineers and students. Although, its not as difficult as it seems so I thought to post about it. In today’s post, we will first simulate the Relay in a simple circuit in which when you run the simulation, the relay will automatically got activated and after that we will go in a bit detail and will control relay using a logic, i.e.
When you provide +5V to it then the relay will go activated and when you give GNd then it will de-energize. I will explain it below in detail how to use it with Microcontroller. Moreover, if you are planning to work on Relay then you should also check and should also have a look at and finally must check this one as well.If you have any questions. Related to it then ask in comments and I will try my best to reply your queries. Let’s get started with designing of control relay in Proteus ISIS.
Simple Control Relay Circuit in Proteus ISIS. First of all, we are gonna simulate a simple control relay circuit in which we will manually turn on or off the relay. Open Proteus ISIS and select the below components, as shown in below figure, from the components library of Proteus, if you don’t know how to do it then check our earlier posts on Proteus. Now, design a circuit as shown in below figure:. The circuit is self explanatory, first we have used a simple 12V battery to power up the simulation, after that there’s a small led attached, which will indicate that whether proper power is supplied to the system or not. Next is our relay, which is named as RL1 in the above figure. After the relay, we have placed a simple 12V lamp, so now when the relay will be energized, this lamp will glow up and when the relay is de-energized, the lamp will remain off.
As in the above figure, the simulation is off, that’s why the lamp isn’t glowing. After designing the circuit, now click on the run button and if everything goes fine, then the lamp will glow as shown in below figure:. So, now you can see the small led is also ON, I have used green that’s why its showing green color indicating that power supply is working.
If you compare the off state and on state simulation then you will see that the Relay is now connected with second terminal and thus completing the circuit for lamp and lamp is also now glowing.
