Gammon Forum: Electronics: Microprocessors: How to make an Arduino-compatible minimal board. The bootloader simplifies subsequent programming, as it accepts programming commands from the serial port. This is because with serial comms one side transmits and the other side receives. Trader & Service Provider of Arduino Freeduino offered by Ventor Technologies, Kolkata, West Bengal. Atmega328 With UNO Bootloader (Optiboot). Atmega328 With UNO Bootloader. This is the third revision of the board: the Arduino Single-Sided Serial version 3, or s3v3, or Arduino Severino. Ask For Price. Elektroinstallation symbols pdf download. I designed a PC Board with the free version of Eagle, and the shield fits directly onto the Arduino UNO. After designing the layout of the board, I noticed that the. Single sided PCB (easy to manufacture); Arduino compatible form factor; LED's for power and pin 13; Easy to access reset switch; Prototype area; FTDI Connector for serial communication; On board crystal with decoupling caps; Minimal cost (due to PCB and component count). In this, my first Instructable I'm going to show you how to make a stripped down Arduino for a fraction of the price, using Stripboard/Veroboard. Material List: 1x Atmel ATMega168 = �2.65 1x Stipboard = 72p 1x 7805 Voltage regulator = 26p 2x LEDs = 16p 2x 220 Ohm resistors = 8p 1x 10k Ohm resistor = 4p 2x 10 uF capacitors = 12p 1x 16 MHz clock crystal = 45p 2x 22 pF capacitors = 10p 2x.1 mfd capacitors = 10p 1x small momentary button = 18p # small amount of wire for jumpers Total = �5.94 (All prices based on single component prices from ) Step 1: Cutting the Tracks. Thanks for a fantastic Instructable. I'm new to all this arduino and instructables stuff and needed to re-teach myself soldering after a 15 year break but you can imagine my excitement and sense of satisfaction to follow this all step by step and witness the blink sketch flashing my LED on my very own arduino clone. Ac212 migration to the new general ledger pdf. I did get a little confused at first with the voltage regulator capacitors but good old google managed to sort me out. My mind is running away with me as to the next things I need to do, but THANKS AGAIN for your help with this step up the ladder. Onwards and upwards! PS How did you create the pictures of the strip board showing the component layout and tracking cutting plan. I want to create some similar images for my next project which may well turn into an instructable too. If you don't cut the tracks the energy will just flow by the components on the board, because electricity will always go the way with the lowest resistance, the tracks have nearly no resistance the components on the board have a higher resistance. With the stripboard you just replacing the copper tracks (low resistance) with air (high resistance). Just imagine a river (low resistance) that splits in 2 directions, if you want more water in one direction you just have to block some water on the other direction with a dam (high resistance). I hope my english didn't hurt to much ^^. ![]() ![]() Hi Scytheon3, No need to be apologetic, they are all very good questions! 1) what voltage is the 10uF capacitor The ones i used are 16V, but you can use 25V too.as your not going to be using more then 9V as a power supply. 2) I cant find a.1mfd capacitor.1mfd is also called 100nF (try a search for 100nF) 3) Is the momentary switch like the one in the picture with 4 pins (below) Yep that's the right type, the main thing to look out for is that it is a 'momentary switch' so only on when your holding down the button 4) How do you connect it to a computer and program it This bit is a little more tricky, you have two options 1: buy a AVR programmer like the 2: build your own Ghetto-Programmer like one. Then follow he guide on adding a ISP to the Stripduino.I think iv done one. Its also worth getting your Chip with the Arduino bootloader already loaded.most places off that for only a fraction more, and will save you lots of time and stress. Sure you will have more questions, so feel free to PM me any time.
