3*3*3 LED cube using arduino uno

Hello Friends,

In this post, we are going to make 3d led cube using arduino. It's 3*3*3 led cube, so require a total of 27 leds. For driving 27 leds we require driver IC like ULN2003.

List of components:

• Arduino uno
• 27 LEDs
• ULN2003
• Perfboard
• 8 220 ohms resistor
• Jumper wires

Line follower robot using Atmega8

In this post, we are going to make a line follower robot using atmega8. Line follower robot is based on tracking a line of particular colour. This is done by infrared (IR) sensor. IR sensor gives us a digital output.

Things required:

1. Atmega8a 
2. L293d (H-bridge ic)
3. DC geared motor
4. chasis
5. 2 Ir sensor
6. Power supply (9 volt battery)

Sending SMS using Atmega16

Hello Friends, in this post we are going to send text sms using atmega16a and Gsm module.

First of all, GSM module is communicated using atmega16a using serial communication.

Stuffs required:

1. Atmega16a 
2. GSM module
3. 12V, 2A dc adapter
4. Sim card having sms pack
5. Some jumper wires

Connection:

Make connection like this.
