I ran across this little bot while searching Picaxe projects. I found it quite interesting how he uses the 08M to control a SN754410 motor driver chip and a Sharp IR sensor. Not sure if anyone has seen this bot before but I liked how it worked. The OP includes a schematic, code and video...

Just finished building this bot yesterday. It looks a lot like one I made 2-yars ago but with some improvements. New robot is more compact, has ultrasonic sensor instead of a Sharp IR. Motor is from an old floppy drive and the gearbox is aluminum bar stock with gears and tires from slotcars...

A few years ago I made this solenoid engine. The operation uses a Hall effect sensor to fire a transistor (TIP 105) to switch on the solenoid current. It stays on for about 30 degrees of flywheel rotation and shuts off the transistor. Max speed @ 9vdc is about 180-200 rpm. Here is a link to the...

Hello All, I built a robot using the 08M2 chip. I have a write up on it on this website: [URL="http://letsmakerobots.com/node/8408"/URL] It ran ok with the original code but I wanted to update it. Here is the updated code: '**************************** 'Robot#2_R1.bas 'Picaxe 08M2...

Greetings All, I have built my BeerBot and have it in the Blogs. The final bit of wiring I need has not shown up in many searches. I use 2-protoytpe boards. The AXE118 with a 20M2 and the 08 Protoboard with the 08M chip. 08 runs the Tenda Speech board and the Adafruit Audio amp great. 08...

Here are a couple more photos of my Robot. Am still looking for the way to wire up my 20M2 and 08M protoboards so I can send a signal to play a certain phrase based on the program.

I started working on this robot about 3 months ago. It uses a RevEd Axe118 20M2 Project Board as the main controller. Another board, L293D handles the drive motor. Steering is done with a standard size servo and a smaller SG90 size rotates the Sharp IR Sensor. I made the sensor plug-in board...

Greetings, I have finished the build of my project and now for the controller. Reading the manual and searching the Forum it looks like the 08M2 will work with 6 I/O available. Here is the list of what I need to control with what I think will work : 1. Single Motor control thru an L293D...

Greetings! I am building a line follower robot and want to use the -08M chip with the Proto-Board. The mechanical is done with (1) motor for the power and a servo to steer. A IRF510 controls the motor on-off and the servo does its job. MOSFET gate is on Pin0, Servo signal is on Pin1. I want to...

I recently bought the CHI035 Hi-Power board with a Picaxe 18X chip to build my robot. Motor outputs work fine (Out 4 thru 7) with the L293D chip. I see the Out 0-3 are FET controlled. Don't believe I can use them with a servo. Is there a way to run my servo with this board? Thanks.

Good Evening! Thought I would share with you my first post and PicAxe project. I was looking for an interesting project to tie my PicAxe and my other hobby of slotcar racing together. Thought about building a motor dyno and here are the results. The controls are not completely done yet...
