In this DIY session we are going to use a 32×16 LED dot Matrix display module which is also known as P10 LED Display Module to display a scrolling text by using Arduino UNO. P10 modules can be cascaded to build any size of the advertising board.

Here we are going to design a prototype for Automatic Bottle Filling Machine using Arduino Uno, conveyor belt, solenoid valve, IR sensor, and Stepper motor. Belt conveyor is driven by a stepper motor at a constant preset speed. The stepper motor will keep driving the belt until an IR sensor detects the presence of a bottle on the belt. We used the IR sensor as an external trigger. So whenever the IR sensor goes high it sends a trigger to Arduino to stop the motor and turn on the solenoid valve.

The basic idea of this Arduino Water Fountain is to take an input from any external sound source like mobile, iPod, PC etc., sample the sound and break it down to different voltage ranges, then use the output to turn on various Relay. We first used a condenser mic based sound sensor module to perform on the sound source to split the sounds into different voltage ranges. Then the voltage will be fed to op-amp to compare sound level with a particular limit. The higher voltage range will correspond to a relay switch ON which comprises a musical water fountain operating to the beats and rhythms of the song. So here we are building this Musical Fountain using Arduino and sound sensor.

VL6180 differs from other distance sensors as it uses a precise clock to measure the time taken by the light to reflect back from any surface. This gives VL6180 a benefit over other sensors because it’s more accurate and immune to noise.
The HM10 has become a very popular Bluetooth 4.0 BLE module. The HM10 is a Bluetooth 4.0 based module only, so it will not connect with Bluetooth 2/2.1 module such as HC-05, HC-06 and other Bluetooth modules. The HM10 is controlled via AT commands sent over the serial UART connection. HM-10 is a Bluetooth Low Energy (BLE) module, to know more about this module, check out the HM-10 BLE datasheet.

In previous tutorial we have discussed about MQTT Protocol and installed local MQTT server on our Raspberry Pi for controlling the GPIO locally. But the drawback of local MQTT server is that we cannot control the GPIOs from anywhere in the world, it only provides services locally. But if this MQTT server is hosted on some cloud then any appliances connected to Raspberry Pi can be controlled globally.

DIY Arduino Based Color Sorter Machine using TCS3200 Color Sensor
Here in this tutorial we will make a color sorting machine using a color sensor TCS3200, some servo motors and Arduino board. This tutorial will include the sorting of colored balls and keeping them in the relevant color box. The box will be in the fixed position and the servo motor will be used to move the sorter hand to keep the ball in the relevant box.
