Sorry for the delay - sometimes life just gets in the way. Here's my circuit diagram I have solved the problem. In writing my program I accidently assigned two separate Symbols to the same pin 2, first to "STOP_BUTTON" which was to be a button which would stop the loop in "morse_SPMBC:" when...

Hello All. Apologies if this has been asked before but I have a issue with a piezo speaker. I am testing a simple morse code beeper connected to a Picaxe 08. The program uses the command: sound 2,(90,12) and works fine if the piezo is connected, but if I disconnect the piezo the program...

Hello, I have a problem with a Seven segment display not showing the numbers 1,2,3 and 7 in a simple looping count. First some specs: PICAXE 28A 74HC595 Shift register driving a common cathode display. I have tried two different shift register chips so it's not the chip that's the problem. All...

Hello all, I am using an old PICAXE 28A chip that I bought about in about 2003! (which I want to keep using). My question is regarding the 'if then' command. In the current manual this is the command example: if pinC.0 = 1 then goto flash but I have seen people using the example: if...

Success ! Thankyou for the encouragement and information guys. Using westaust55's info I successfully tested the circuit. This is a diagram of circuit driving an LED for the benefit of others. Cheers Andrew

Hello everyone, As a newbie I am trying various different circuits on a breadboard before hooking the completed circuit up to a PICAXE. I have assembled a ULN2003 with an resistor/LED on an output. The circuit is on 4.5VDC. My question is how can I switch the input without using a PICAXE - ie...
