Arduino Led Projects app for Android

Another arduino related app for people with Android devices. This one focuses on LED related projects

The Arduino Led Projects app consists of

1.Blink an LED
2.Fade LED
3.Fade LED using pot
4.LED control by button
5.LED by serial monitor
6.LED using photocell
7.Led using Relay switch
8.Led using Bluetooth Module
9.Led using IR sensor
10.Coin Flipper
11.Led temperature indicator
12.Knight rider
13.Traffic Light
14.Led pendulum
15.Police Light
16.Back and forth scanner

This app contains various LED related projects for your Arduino, schematics look clear enough , a parts list is supplied and the code is clear enough to read.

The app is a bit heavy on the interstitial ads which can be annoying, that is the trade off for it being free I’m afraid








Arduino Sensors Tutorial app on Android

This app is a guide to Arduino Sensors

the app consists details of basic sensors used in arduino programming it consists of the sensor details ,circuit diagram and code for each sensor

The sensors covered in this app are
1.Ultrasonic sensor
2.IR obstracle avoiding sensor
3.Soil moisture sensor
4.Microphone sensor
5.Barametric Pressure sensor
6.Photoresistor sensor
7.Temperature sensor
9.Gas sensor
10.Vibration sensor
11.Rain detection sensor
12.Passive buzzer sensor
13.Speed sensor
14.IR flame sensor
15.Relay module
16.PIR sensor
17.Accelerometer Sensor
18.Temperature and humidity sensor
19.Rf transmitter and receiver
20.Joystick Shield

This app has 20 sensor type examples for the Arduino, I would have liked the code to have been spaced out a bit better and also on the same page as the layout but as this is a free app you cant really complain I suppose, it does contain ads as well








Ardu Companion iPad app

Ardu Companion is a companion t0 use in your daily projects and experiments with electronics prototyping.

The tools include: calculators for Timers, PWMs, ADCs (these three tools are for free and 100% functioning), other tools include: sample codes for timers, PWMs, ADCs, watchdog, debouncing and serial-data management, tools to obtain the values of resistors and inductors from the color codes on the components, the Ohm’s law, calculators for RC/RL/LC/RLC filters, voltage dividers, the series/parallel resistor circuits, the time for charging capacitors, the usage of op-amps, how to calculate the resistor for LEDs, how to configure an LM317 voltage regulator, how to use an NE555, and how to calculate the heat of a silicon junction (these tools are offered with in-app purchase of $1.99).

When using the calculators for timers, PWM, and ADC, if you tap on the “?” button you’ll get a brief explanation on how that peripheral works and what are the registers to configure it (tap on the floating info window to close it). Fill the required fields and tap on the Compute button to calculate the values you need. Tap on Clear all to clear all the fields.

I would have liked there to have been another couple of tools for free to entice you in personally, I will admit the price of $1.99 to upgrade is reasonable though and won’t put a dent in the wallet. One thing I commend the developers for is not simply rehashing the Arduino online pages in an app, the amount of those I have looked at is not funny – admittedly mainly on Android devices.

I have a video of the app and I navigate through the freely available tools



Here is the app on my iPad

Arduino Pocket reference on the iPad

I’m always interested in apps onthe iPad or android devices that are related to the Arduino or electronics in general, in this case I took a look at Arduino pocket reference which fitted the bill as it was free.

The first thing that is obvious with a lot of the arduino apps is that they seem to have basicallt borrowed all of the creative commons content from the arduino website. With regards the content I had a quick flick through and found a couple of bugs or things that I think could have been better.

An LED example with no resistor connected to the output pin of the arduino – bad practice
Another LED example with 5 LEDs on the layout and 6 on the schematic
Inconsistent code fromatting – would prefer all code snipptes to be highlighted
Some of the layout images were incorrectly sized

I have linked to  my video so you can have a quick look yourselves
