Hi Could someone possibly offer any advice. I have the circuit shown in the diagram using an 08M2. I need to work a 12v relay so when C.1 is high C.0 goes high but I'm not sure how to organise the 12v and 5v circuits. With this circuit the relay coil energises all the time so I have obviously...

I'm new to the Picaxe so would appreciate any help. I have a switched 5v output from a device I want to connect to an input pin on an 18m2 project board to give a high or low. There are two sets of holes on the input side (outer holes C.0, C.1 etc) the outer holes are connected to V1+ and the...

Sorry about this but I am at a loss with the stepper motor 28BYJ 48 control and wiring. I have an 18m2 project board which I have successfully controlled dc motors with but I am needing some help with this stepper motor. I want it to turn 2/3 of a turn in approx 5 seconds (time not critical)...

Hi can anyone help. I'm using a picaxe 18m2 with darlington driving a 12v dc motor in turn driving a wheel. As the wheel passes certain pinch points in each revolution the motor draws more current as more torque is required. Is there a way to detect when the current increases over the normal...

Could you please advise whether the Picaxe - 18 project board CH1030A comes assembled or in bits. Thanks

My programme works in simulation but does not when downloaded onto a picaxe 18m2. The wiring connections are all checked and double checked. The programme turns a 12v motor on and off depending on number of revs determined by magnet passing reed switch. A fairly simple on of code works but once...

I'm using an 18m2. I am connecting a 5v relay to pin B1. As it only takes 30mA I assume I do not need a buffer and can connect direct to pin B1 and 5v+. Do I need the back EMF diode though? Thanks for any help you can give on this.

I want to take an analogue input from a pot to a picaxe 18m2 project board. The pot is connected to a motor speed control circuit which in turn is connected to a 12v battery. The picaxe supply voltage is connected to the same 12v battery but is a seperate circuit. The three pot terminals are...

It is an 18m2 CHI030B. I connected to the PWR V & G terminals with the correct polarity. If I have wrecked it what parts do I need to replace? Thanks

I connected my 18m2 project board to 12v. Will it have ruined the chip and also the darlington driver and anything else? Regards

Hi I have an 18m2 project board with a darlington driver ic. The manual shows items connected directly to inputs without the 1k resistor. The manual says the board is fitted with the 10k resistors but do I need to insert the 1k before digital inputs. Thanks for any help.

I'm pretty new to the Picaxe so I would appreciate any help anyone can give. This is a programme I have basically copied from the Picaxe manual. It is to count the revolutions of a shaft via a reed switch and then switch on an LED after 5 revs. There is a rotary switch in the circuit which...

Hi I want to reset a latched switch operated by a Picaxe 18 pin by pressing a button connected to the reset input. I do not want the switch to reset if a pot in the same circuit is turned on. It is not a switched pot so can I input the resistance from the pot into the picaxe to prevent a reset...
