Relay for micro:bit (micro:bit Relay board)

The MonkMakes Relay for micro:bit is a solid-state (no moving parts) relay that allows an output of a micro:bit to turn things on and off.

A micro:bit can turn an LED on and off directly, but anything more powerful requires something like a relay or a transistor. Using a transistor to switch something on and off requires a shared ground connection with the micro:bit and a knowledge electronics that you or your students may not be ready for. The MonkMakes Relay for micro:bit is much easier to use, acting like a simple micro:bit controlled switch.

This relay can be used to switch low voltage devices such as light bulbs, a motor, a small heating element or even a string of 12V LED lighting. The voltage needs to be kept under 16V, but the relay will automatically protect itself against too much current.

FEATURES

  • Solid-sate relay (up to 2 Amps)
  • Active LED indicator
  • Resettable ‘polyfuse’ to protect against over-current

Getting Started with your micro:bit

Connecting your micro:bit

The Relay requires just two connections to the micro:bit. One to GND (ground) and one to whatever pin is to be used to control the relay’s switching action.

When attaching the alligator clips to the micro:bit, make sure that the clips are perpendicular to the board so that they are not touching any of the neighbouring connectors on the micro:Bit edge connector.

Here’s an example of how you could wire up a MonkMakes Relay for micro:bit to turn an old fashioned light bulb on and off.

HEX File

The quickest way to try out your relay is to DOWNLOAD THIS HEX FILE >and then copy it onto your micro:bit. The program will turn the relay on and off once a second.

JavaScript Blocks Editor

Set the controlling pin to 1 and the relay contacts will close, set it to 0 and the contacts will open again. Its as simple as that. So, to make your relay turn on and off once a second, open the Blocks Editor, add a forever block and then the digital write blocks from the pins category and the pauses from the basic category.

MicroPython

Paste the following code into the Python window and then Download the file and copy it onto your your micro:bit.

from microbit import *

while True:
    pin0.write_digital(True)
    sleep(500)
    pin0.write_digital(False)
    sleep(500)



Analog Outputs

The latest MonkMakes Relay for micro:bit can do more than just switch things on and off. It can also be used with micro:bit analog outputs. Look closely at your Relay for micro:bit and is it has the version number v1ev (under the word ‘Board’) then it can be used with the ‘analog write’ block in the blocks editor or the ‘write_analog’ function in MicroPython. If your board has the version number v1e then it is not suitable for use with analog outputs – sorry you were unlucky to get one of the small batch of first boards to be sold.

The output of the Relay for micro:bit is not linear at low PWM and high PWM values as the following chart illustrates.

The y-axis shows the current in mA for a test load resistor supplied from a constant voltage source. The x-axis is the analog write value (0 to 1023). As you can see, there is a dead zone up to a analog output value of about 100, followed by a relatively good linear region right up to about 1000, after which the output effectively becomes ‘on’.

The tests were carried out at the default PWM frequency of 50Hz for the micro:bit. Lower frequency PWM is expected to produce more linear results.

The MonkMakes Relay for micro:bit is a solid-state (no moving parts) relay that allows an output of a micro:bit to turn things on and off.

Depending on how hard your relay works, you might want to add a heat sink to it.

Q:During continuity testing with my multimeter why does my relay on the AC side not switch on?
A: The below info was found at http://www.crydom.com/en/tech/newsletters/solid statements - bench test an ssr.pdf

A multimeter determines impedance by injecting a small amount of voltage through it's probes into the circuit being tested. It then measures the current flowing through the probes and calculates resistance. Easy enough; Resistance = Voltage / Current! However, as we just discussed above, a solid state relay’s output turns on by “stealing” a bit of voltage from the AC mains in order to supply current to the gate of the SCRs. Simply put, if the AC mains is not connected to the relay then the output cannot turn on. Since the voltage and current produced by a multimeter is not sufficient enough to turn on the SCRs, the output of a solid state relay will remain in the off state; even with the input signal applied. As a result, SSRs will sometimes fail an incoming inspection because the engineer expects to see a significant change in the output impedance when they turn on the relay.The most effective way to bench test a solid state relay is to construct a simple test circuit consisting of a DC power supply or battery (a 9Vdc battery will work fine in most cases ) and a 60W or 100W light bulb.

CH4: 2 relay module signal trigger terminal (low level trigger active)

High and low meaning

High-level trigger refers to the signal trigger side (IN) and the negative power supply has a positive voltage between the positive and the power supply is usually connected to the trigger side of a trigger, when the trigger side voltage or trigger to reach the trigger Voltage, the relay is pull.

Low-level trigger refers to the voltage between the signal trigger terminal and the negative terminal of the power supply is OV, or the voltage of the trigger terminal is lower than the voltage of the positive terminal of the power supply. When the voltage is low enough to trigger, the relay is pulled in, The negative side of the power supply is connected to the trigger side of a trigger, so that the relay is pull.

Instructions

1. Module power supply: the power must be DC, the voltage and the relay voltage to match
2. Wiring method:
When the trigger side of the signal trigger level, the relay will be connected, the device has electricity and work

Notes
 
1. Module power supply: power must be DC, 5V power supply
2. Module control terminal voltage: This module can only be used to control AC current, can not control DC current.

1CH Active H/L 3V OptoCoupler Relay Module (1ch 3V Relay)

Relays are always good to have especially for electronics projects. The relay itself offers two main benefits:

  • Isolation of low voltage system against high voltage system, example 5VDC and 240VAC
  • Allow electronics with low voltage to control high power load, for example from Arduino to AC light bulb.

This is not an ordinary Relay breakout. It comes with 1 (single) channel 3.3V activation relay, ready to control 250VAC at 10A. Extra isolation with optocoupler at the front of control and the activation logic for the relay is configurable via a mini jumper. In simple words, the relay can be configured as 3.3V(High) activation or 0V(Low) activation. This is the universal Relay breakout board and we like it.

It comes with three (3) screw terminals for the relay output:

NO (Normally Opened),
NC (Normally Closed),
COM (Common),

and screw terminals for the control signal from a microcontroller such as Arduino or micro:bit. The control signal is optoisolated, protected. It even comes with power and activation indicator LEDs for the relay. Easy to use and suitable for beginners, and of course students too.

Input power and signal:

  • DC+ = +3.3VDC
  • DC- = GND (Ground or 0V)
  • In1 = Control signal, 3.3V as logic High; 0V as logic Low

If you need to control AC or high current, high voltage load, this will be the perfect board.



Note: We notice the DC+ and DC- need to be 3.3V and the In1 (control signal) needs to be 3.3V or Ground to make it works properly.

Features

  • 3.3V One (single) channel relay module
  • Configurable Activation Logic, High or Low, via mini jumper
  • Maximum Current Rating: 10A
  • Maximum Voltage Rating: AC 250V
  • Can control various appliances with large current and high voltage
  • Can be controlled directly by 3.3V microcontrollers such as Arduino, micro:bit.
  • Build-in an Opto-Isolator for extra isolation and protection to the controller.
  • A power indicator LED, and another relay activation indicator LED
