It is just another ‘build your own Arduino’ project. BuildCircuit has worked on similar projects before. The most popular project is a DIY Arduino kit. The DIY Arduino looks similar to the real Arduino boards and uses an FTDI basic programmer to program the chips.
The kit that we are going to work on this article is also a DIY Arduino. It comes with a zero insertion force (ZIF) IC socket. You can simply insert an Arduino chip and program it. The board has a header to connect an FTDI basic module that can be used to program the Arduino chip.
Amarino lamp is fully programmable. The kit package consists of FTDI basic breakout board, you can use it to program the lamp. The lamp is based on Arduino.
Connect the FTDI basic breakout board to the lamp, open the Arduino programming interface and upload your sketch.
REMEMBER: Turn off the red colored 1P DIP switch while uploading sketch(if the Bluetooth module has been stacked over the 4 pin female header)
Description: Here’s a simple DIY clap switch circuit. The circuit is mainly composed of an audio frequency and a bistable trigger circuit.
Q1 and Q2 together form an amplifier circuit. MK1 (electret microphone) accepts Clap/Audio signal and that enters to transistor Q1 through the coupling capacitor C1 and enters to Q2 base through collector directly after getting amplified. And it obtains a negative square-wave which used to trigger the bistable circuit from Q2’s collector. (more…)
We are now selling the BLUE COLORED DIY Arduino kit
This post shows you how to assemble the DIY Arduino board.
The assembly process is straight forward. It can be easily assembled if you follow the silkscreen indicators(labels) and have beginning experience with a soldering iron. You will need to read the resistor bands or use a multimeter to determine the resistor sizes.
Note: You will need either an FTDI Basic or FTDI cable to load code using the Arduino IDE.

1 x Arduino-Compatible plated through holes (PTH) Kit PCB
1 x ATMega328 with Optiboot bootloader

Description of this DIY Arduino board is available on this page.
You will get the following components with the kit package. You can purchase this kit at buildcircuit.com.au. The web store is operated by BuildCircuit team.
Look at the PCB below.You can see the silkscreen indicators/labels of the components. If you follow the labels correctly, you can easily assemble all the components on to the circuit board.
PCB dimension: 31.75mm x 31.75mm
Step 1: Start with resistors. Solder the three resistors- 330R, 390R and 240R. Click on the resistors to get the color code.
Step 2: Then, fix the diode 1N4001. You can also use 1N4004 or 1N4007. All work the same way.
Step 3: Fix 0.1uF (code-104) capacitor.
Step 4: Fix the 2pcs of SPDT switch. One switch is for ON/OFF function and the other is for switching 3.3V and 5V.
Step 5: Fix the 5mm red LED. It works as a power indicator.
Step 6: Fix the PTC resettable fuse (500mA). This is a handy little device that can save your system from burning. A resettable fuse (also known as a PTC) is a resistor that has very unique properties.
For this kit, if your circuit tries to draw more than 500mA of current (if you have a bad short for instance) the PTC would ‘trip’ (by heating up). The increased resistance (trip state) would break the circuit and allow only a small leakage current.
Step 7: Solder the 330R resistor. It works as current limiting resistor for the 5mm LED.
Step 8: Solder 100uF and 10uF capacitors. Please be careful with the polarity. Wrong polarity will burn the components. The silkscreen indicators should help.
Step 9: Solder the LM317 chip and DC barrel.
Step 10: There are 2pcs of 2-pin male header for fixing the circuit board into the breadboard holes. You need to solder them as shown on the image below.
Give a close look.
Step 12: Fix the power supply into your breadboard using the male headers. Power up the circuit with any DC supply (6-37V), it will give two outputs- 3.3V and 5V(one at a time).
The kit is ready to use for your projects. Fix your project components on the remaining part of the breadboard.
Description: Here’s a simple do-it-yourself (DIY) remote operated switch. You can use this simple kit to switch ON/OFF any appliances working on 220V AC. This DIY kit has been designed basically as a learning kit rather than as a household device. With this kit, you may learn about relay and infrared sensor. It can used for fun at home for switching appliances operating on 220V AC. (more…)
This is a simple 4-in-1 do-it-yourself (DIY) kit from BuildCircuit. The kit has four different circuits that can be switched on separately or together at a time using a DIP switch.
