1. Priciple Photocells are sensors that allow you to detect light. They are small, inexpensive, low-power, easy to use and don't wear out. For that reason they often appear in toys, gadgets and appliances. They are often referred to as CdS cells (they are made of Cadmium-Sulfide), light-dependent resistors (LDR), and...

We have a lot of NTC 10D-9 sensors and another similar sensors in stock, now we have a simple tutorial about how to use this one. You can get the NTC serials sensor here. First according to the datasheet, temperature and resistance is a function of the relationship. Rt = R *EXP(B*(1/T1-1/T2)) Of the above...
We have the TCRT 5000 sensors in stock, it's a pretty cheap $0.35 for 2 pcs, and easy to use sensors, you can find the product here. Now we found a detailed tutorial about how to set it up and use it from Bajdi blog, see the wiring and sketch below....
When you get our OLED, they are followings so may have to do before you start to use it. It's a quite cheap and easy to use OLED, offering a few communication protocol 68XX, 8080, 4 wires, 3 wires and I2C, we are now going to try the 4 wires. It's...
Why design your own arduino shield? It's cheap, our stuffs you need only cost 1-2 USD, and it's also easy and fast to build. We are going to a bluetooth adapter, an official one need $19. Wiring is annoying, how many times you made wrong wiring.. (more…)
When we are doing PID test or Kallman filtering via collecting data from arduino monitor, if any tool can send data bck to computer in real time, analyse, and then generate chart, that will very helpful. now this is a tool can do it. The SNV address of the software are http://code.google.com/p/serialchart/ How...
Posture recognition are widely used in many field, such us self balanced car, helicopter, two-feed robot, etc. Now we use arduino + ITG3205+ADXL345 to fulfill the posture recognition, and using processing as output to display posture in real time. ITG3205 and ADXL345 module are the final built version, you can use directly...
