Intro

Intro: Arduino R/C Lawnmower (painted)

What this is: This instructable will show you how to make your Arduino into an R/C interface that you can use for just about anything requiring remot...

Step 1: Setting up

1. Get R/C transmitter and receiver (I have tested FM and AM systems and they both work) 2. Upload code to Arduino (it is on the last page) 3. Make su...

Step 2: The Motor Driver

I built several motor drivers before finding a design that worked for my needs. For what it's worth, there are several nice products already out there...

Step 3: The Wheels

First you need to mount the drive sprockets to the wheels. The EASY way:If you are smart and have more money, you can find a set of wheelchair motors ...

Step 4: The Frame part A

This is the difficult part to explain. You will likely have to have some mechanical ability and a good set of tools to build a large metal frame from ...

Step 5: The Frame part B

We now need to see how far down to mount the drive axle to make the frame level. So raise the rear of the frame up until the top of the frame is level...

6

Step 6: Mounting the motors

This was the most difficult part to plan out on the frame. We need the motors to be adjustable so we can adjust the tension of the chain, however they...

Step 7: Mounting the mower deck

Next we need to mount the mower deck to the frame. Remember we made the frame wide enough that the edges of the frame would be centered on the lawnmow...

Step 8: Select and Install the batteries

This is the simple part. Go BIG. I only bought 1.. which I got at Walmart for $62.I got 2 car batteries (actually 1 marine deep cycle and 1 gel-cell c...

Step 9: Mount the electronics

Connect the electronics to the motors and batteries. The motor drive board has 1 connector for the main battery power and 1 power connector for the 80...

Step 10: The Code

I changed the code so that the Interrupt Service Routines (ISR) would run more quickly and the sketch would spend less time in the ISR. This means les...
