Atmel Car V0.1
As promised, I will continue today. Yesterday I mentioned about the projects that I would be doing. Today I will describe what was already done and what are the next steps.
So far, I’ve bought a simple remote controlled car, disassembled it, removed the original circuit. Then I used two external servo motors, took their circuit, and connected it to the electro motors in the car. I screwed the Atmel research board on the “trunk” of the car and mounted a bluetooth module on roof. I also connected the modules between each other.
- Front wheels on the PIN PD7
- Back wheels on the PIN PB3
- Bluetooth module BT0417C works over UART standard so I plugged it to PD0 (Tx) and and PD1 (Rx) on Atmel MCU.
Assembled everything again. I am really sorry for the bad pictures but I have a supplementary phone which is not the best machine in the world :).
I also wrote a short “dummy” projects which steers the car in a random way. So every 2 seconds the speed and direction of the car changes. Everything so far easy and simple, but it still takes some time.
And the most important thing, start programming the Android. I do not know why, but I never managed to come further as “hello world” with the template that is already made for you in the Android SDK.
