Hi guys,
I'm currently working on a vacuum cleaner project. (Arduino based)
One of the specification proposed is that the robot is able to return to the base, after the cleaning process is done.
Is there any recommended approach or algorithm for doing this ? (For eg, IR ?)
It will be great...
Yup, I'm currently using a power bank & USB cable to supply my robot.
Is it not appropriate to do so ?
Another ques : Is there any significant difference by using LiPo battery & power bank ? :)
Hi guys,
I'm currently working on a vacuum cleaner project, which can be triggered wireless through GSM shield module.
Main components that I'm using are:
- Arduino UNO
- Two DC geared motors. (draws 0.1A each)
- One micro Servo. (draws approx. 0.2A)
- One turbine fan. (draws 0.1A)
- One GSM...
Hi guys, I'm currently working on a humidity project.
I'd bought the "SN HMD MOD" (HR202) sensor , https://img.dxcdn.com/productimages/sku_152031_1.jpg
The sensor is basically consists of 4 pins (Vcc, GND, AO & DO). May I know what is the formula or equations to calculate humidity ?
Full PIC...
Hey guys, I had just received my assignment , and seriously, I need help to understand it :???:
1.) What is Curve Tracer ?
2.) What is Voltage Controlled Current Source ?
3.) What is Device Under Test ( DUT ) ?
4.) What is current sensing resistor ?
5.) How these things work together to become...
Hey guys, I just got my assignment ... the task is to design a harmonic oscillator with :
Frequency of oscillation = 1 kHz
Amplitude of oscillation = 5 Vp
any idea to do it ??? thanks :grin:
ok guys, I had spent almost 1 day to do the nodal analysis with my coursemate...here's the link, 1st and 2nd Circuit Block Analysis.pdf ...
tell me if we had made any mistake , thanks alot...
sorry for the late reply, I had made a discussion with my coursemate today, and we seperate the circuit into 2 circuit ... here's the link , Circuit Analysis.zip ... we think that the 1st part is high-pass filter, and the 2nd part is low- pass filter ... is that correct ? and how do u think...
yup I think it needs power supply ...
well, my lecturer gave us 1 week to do this assignment , I haven't learn anything about Op-amp yet, so now still in researching stage ... :-?
or you can try download the image, here's the link ... **broken link removed** ... 69.24kb
sorry that I don't know which site allow us to upload photos, except blogspot >.<
maybe I send you the image link ?... https://2.bp.blogspot.com/-ko3uqq0pn7Y/Td0zz2LrbDI/AAAAAAAAAAM/m7fEcDitS2c/s1600/Assignment1opamp.jpg ... hope you can view it ...
My lecturer just gave me a new assignment ... it's about operational amplifier, although he haven't teach us anything about Op-amp, but i wanna ask , what do you understand for the circuit below ??? Just want to know some suggestion, really appreciate your help ~~~ :smile:
