Hi, I am only using one voltage at a time. like plugging in a 12v bulb or a 24v bulb. but use picaxe command to switch between 12/24v
only 1 circuit for 12 and 1 for 24
current is less than 500ma ( Car type relay, prox sensor,)
as in previous posts for my project I have 12 volt (regulator) and 24 volt (battery) output on different pins on a plug 24v is then switched with the IRL 520 from picaxe command. to drive external buzzer/sensor/relay/lamp etc
I would like to have the negative as common and one pin as 12/24v...
Hi, thanks for drawing :) I had drawing wrong for reverse protection. (what do people use for drawings, cant find decent and cheap with most components)
Ive not used LM2594, so clueless.. will need to look for circuit diagram... learning. for now there is very low current 24v just used for...
just for info anyone bored and find faults?
Here i have the schematic for my project.
24v battery supplying 12v to 5v, for project and outputs for all
numerous 5v inputs, for switches
triggering 24v out, detecting and measuring a external 24v input
Hi looking to operate a manual toggle or push button switch wired to a box to then wireless send signal to a Picaxe input a few metres away. Any wireless type addons? ones in Picaxe shop never in stock other web sites seem to always be discontinued. Infra red not possible.
I designed board but professional check/made/ they check for broken links etc. it seems strange as getting 1.5 v to pin c3...
seems i get no change on adc reading. but get a change on 1.5 to 0volt on pin... maybe 20m2 is toast?
well here we are again. board was printed and built. 2 of my volt readings are very stable, great thanks everyone... but now one reading is wandering from 150 to 700+ on Word variable W0. this value is greatly changing even if nothing connected
when 24v conected i have stable 1.49v at pin c.3?
Ive been using this for 2 years now.
just wanted something with a stand so i dont keep melting the carpet...
