Away to go then :smile: Thanks again

Thanks for the response; soldered the resistors and readiinng was perfect; comments about breadboards noted with gratitude. Martyn

Seriously its a whole section of a course in one. Thank you; this closes it for me! Martyn

just pcb board connections of 3 series resistors and probes inserted adjacently Martyn

Ok I can live with that; thanks or your help; I will try it with a clean pcb. Thanks Martyn

Thanks I tried every option i could think of before reaching out to you; changed the resistors changed the breadboard and changed the monitor???? just don't know what else to try. Martyn

Its a bare circuit and has been tested at different points. Martyn

Thnks;but when I link the 3 they read 3.7 ohms? Martyn

i have 1.6 ohm 2w resisors 3 samples all of which test 1.6 ohms when linked to meter. when tested through a breadboard they read 2 ohms; an explanation would so much be appreciated please? Thanks Martyn

Ah got the wiring messed up, ok now; apologies for having wasted your time; thanks for your patience! Martyn

i don't know of anything untoward. Originally just the screen functioned with no characters then it just gave up. Am I correct in believing that the wiring previously described is such that the screen should illuminate? Thanks Martyn

Hellol I have pins for this; apologies for subseqquent bold; bold option is not responsive. Compatible with HD44780 1602 16x2 Serial LCD White Character Blue Backlight Display Board 3.3V 5V , Using Arduino Uno. 15 and 16 connected; 16 to gnd via a 220ohm resistor and 16 to 5v. Mtest meter...

thanks, it is viewing the CH340; I've pretty much tried everything; giving up now; have acquired original - v - clone Thanks Martyn

hi; i purchased 3 of these, AZDelivery 3 x AZ-MEGA2560-Board Bundle with Prototype Shield and each is reporting the error message below. I have triple checked every aspect of the set up and all seems in order, cable devices port, board reburn bootloader et al . I have substituted an arduino...

Great thanks; I ave worked out the workbook installation; and I guess when I an up and running writing the code will be a process to learn. I am stuck wit the 'simple' basics of understanding the system; textbooks seem lean on this; any suggestions please? Thanks Martyn
