PIR sensors are widely applied in wireless residential security systems, home alarms systems and many more security circuits as motion detector sensors. A typical PIR sensor detects the infrared red (IR) waves from human body and so it is also known as ‘human sensor’. It would be wonderful if we interface PIR sensor to Arduino […]

As part of the CanSat Primary Mission, we need to measure temperature.  For this our starter kit has given us an Arduino Uno R3 micro-controller, as well as some resistors and an NTCLE101E3 NTC Thermistor. The thermistor is a special kind of resistor that changes its resistance with temperature.  In our case we have an […]

Arduino Uno’s microcontroller board is great, but the one thing it’s not overly generous with is storage. Having 32KB of program flash storage, 2KB of RAM and 1KB of programmable EEPROM space at your disposal is fine for many Arduino projects, but it’s not enough when you need to record data. But with a $2 […]

ABSTRACT: There are several places which require vital notice to be displayed like colleges, railway stations, share-market, restaurants, hospitals etc. Looking into the present trend of information transfer, it is seen that vital notice take time to be displayed on the displaying boards. This latency is not anticipated in most of the cases and must […]

One can use a cell phone with any cellular networks around the globe if the proper SIM card is inserted in it. This is possible because there is some device inside the cell phone which follows a global standard enabling them to connect with different cellular networks. This standard is called Global System for Mobile […]

Here is a useful circuit for Arduino lovers and experimenters. It is a simple digital voltmeter, which can safely measure input dc voltages in 0 to 30V range. The Arduino board can be powered from a standard 9V battery pack, as usual. As you may well know, Arduino’s analog inputs can be used to measure […]

All parts were developed separately. This allowed adjustments in the assembly as well as smaller changes in case the design of one or other part become required. Focus on low cost and use of materials easily accessible in the local market.   For more detail: Homemade Plotter (CNC Machine)

So far in this series we’ve had a diverse look at how Arduino can interact with a range of real-world devices from servo motors to ultrasonic range finders TVs to humidity sensors. Now we’ll see if we could get the Arduino to make a few sounds. We’ll actually do a bit better than that – […]

You’ll need these: HC-SR04 – Get this ultrasonic sensor from eBay.com.au for $2. SG90 Servo Motor – We’ve seen this servo selling for around $4 on ebay. Motor drive shield – You can get this expansion board for $5 online. If you’re new to APC we’ve been spending the last few months of this Masterclass […]

If you ever wanted to integrate touch sensitivity into your project, this board could just do the trick. It’s a capacitive touch sensor. These sensors are used in our everyday consumer electronics like notebook trackpads, video game consoles, touchscreens…just to name a few. They work on the principle of alteration of the electrostatic field. The […]
